ZTD Series Smart Displacer Level (Interface) Transmitter

Summary

ZTD series smart displacer level (interface) transmitter is

produced by Dandong Top Electric Instrument Co. Ltd,

cooperating with Fisher Controls Company. We import

the original DLC3000 series smart level controller, other

parts are designed and manufactured by ourselves. ZTD

is suitable for level, interface or density measurement

with standard output signal 4~20mA DC + HART. By

using HART Communicator which is compatible with

DLC3000 series smart level controllers, not only can you

check, configure, calibrate, or test the smart level

transmitter, but also you can receive the messages from a

single controlling loop and download the information

from site into control system.

Operation principle

ZTD series smart displacer level (interface) transmitter

consists of imported original DLC3000 series smart level

controller and measuring chamber, measuring mechanism,

displacer and torque tube, etc. The liquid level changing

triggers the change of the buoyancy of displacer, then it will

be transferred into the torque tube unit. This makes the torque

tube and core axle rotate synchronously.

At the same time, the magnetic steel parts that fixed at the

core axle of the torque tube turn rotary displacement. The

Hall-effect sensor senses the magnetic field change and

converts the magnetic signals into current signals. DLC3000

series smart level controller measures process variables with

a controller and relative electronic circuit, supplies current

output to drive LCD and support HART communication.

Controller receives the electric signals that have been

temperature-compensated and linearised. Meanwhile,

compensates the liquid density change caused by the change

of the process temperature, then supplies 4~20mA current

output signals. LCD can indicate analog output, process

variables, process temperature (if RTD is installed), degrees

of the torque tube rotation and percent range of variable, etc.

244LD Intelligent Displacer Level (Interface) Transmitter Summary

244LD intelligent displacer level (interface) level transmitter is designed based on Archimedes Buoyancy Principle. It can be used for measuring liquid level, interface and density. The latest model of FDT/DTM technology can provide online calibration and diagnosis, durable in use. A wide range of material selection is suitable for different medium environment. 244LD intelligent displacer level (interface) transmitter in extreme temperature and pressure conditions can be reliable work. This Transmitter is available for any dangerous application. 244LD intelligent displacer level (interface) transmitter is manufactured by Dandong Top Electronics Instrument (Group) Co. Ltd and FOXBORO, The transmitting head and other important parts are original products supplied by FOXBORO, the finished products are as per the original factory standard (FOXBORO).

Operating Principle

The buoyancy of displacer 4 is transmitted to the sensor 3 via lever 1 and the torque tube 2. In measuring range, the voltage is proportional to the buoyancy, and as the input signal is transmitted to the electronic amplifier. Through the electronic amplifier, voltage is converted to 4-20 mA two-wires output signal. In the two-wires system mode, amplifier is powered by the signal current circuit. Any part of the displacer immersed in liquid is adhering to the principle of Archimedes. By measuring buoyancy change of cylindrical displacer suspended in liquid, you can measure the liquid level, interface level or density. When measuring the density and interface level, the displacer should be completely immersed in liquid. The change of the liquid level must be in range area. The calculation of buoyancy: FA= VX·ρ1·g+( V -VX) ·ρ2·g

In the formula：FA：Buoyancy

V：The volume of the displacer

VX：In the liquid density of ρ1, the medium volume displacer swaps out

ρ1：The average of the heavy medium density

ρ2：The average of the lighter medium density

g：The local acceleration of gravity

FG： Buoy its own gravity

UQD Ball Float Level Transmitter

Summary

UQD Ball Float Level Transmitter consists of measurement part and signal controller part.

According to structural features, the measurement part can be divided into 90 type with small

angle, 91type with big angle, 92 type with external float. The signal controller part can be

divided into analog type (UQD.A) and intelligent type (UQD.Z).They are perfect instruments

for liquid level measurement in production process in petroleum, chemical, metallurgy, power

industry and so on.

Operation principle

The measuring unit of UQD ball float

level transmitter includes floating ball,

balance lever, balance weights, these

three elements comprise a torque

balance device. The floating ball can

float up and down freely by level

changing. When the level changes, the

floating ball position changes

correspondingly and drive the shaft to

rotate through connecting rod of the

floating ball. The angular

displacement sensor in the controller couples with the shaft via a pair of gears. In this way, the

changes of level can be converted into electric signal that will be turned into standard current

signal in direct proportion by the electronic circuit in the case.

1. The structure and size 1.1 UQD90 ordinary type ball float level transmitter They have simple structure with easy and convenient installation. They are suitable for

working environment (or container) in which the rod is needed to be long and the range is

small. The angular rotating range (angular home range ) ≤35。

.

(When operating angle range is ≥8。, signal 4-20mA can be output.)

UQD.A-90,UQD.Z-90 Ordinary Type Outline

WWW.DDTOP.COM 19

UQD Ball Float Level Transmitter 1.2 UQD91 big angle level transmitter In order to solve the problem that there is no way for the transmitter working in volume limited

container to increase the measuring range by being extended the length of the ball connecting

rod, our company develops and manufactures 91 type big angle ball float level transmitter

which maximum operating angle can reach 80。. So we resolve the problem that using short rod

to accomplish big range. This technology has been granted a national patent. The patent

number is ZL96 225811.3

Note: The max length of ball connecting rod is not longer than 1130mm.

This type is for large inside diameter container, the max length of connecting rod must

shorter than 1130mm. It is forbidden to extend the rod length at will to increase the

measuring range.

The min inside diameter of container should not less than 400mm.

Here we remind our customer that the limit length of the ball connecting rod is 400mm.

The reason of setting the container inside diameter is to note customer whose container

inside diameter is small.

WWW.DDTOP.COM 20


1.3 UQD92 external float level transmitter 92 external float level transmitter has the same measuring unit and transmission unit as 90

ordinary float level transmitter. The difference is: for external float level transmitter, adding an

external measuring chamber that connects the fluid container through pipeline. So the fluid can

flow into the external measuring chamber with same liquid level as the level inside the

container so that the level can be measured. This type transmitter is suitable to the

measurement that the level is not convenient or difficult to be measured inside the container.

Valve can be assembled between external measuring chamber and container, so it will be

convenient for checking and maintaining.

Note: Flange A is to connect with equipment, DN 40, PN4.0 or DN6.3MPa JB/TB82.2-94

raised face flange or as request. The support for the measuring chamber should be equipped by

users themselves.

generation level indicator according to magnetic coupling

principle. They present the level indication directly and

clearly with advanced technology and the proper structure

and are suitable for petroleum, chemical, power, light

industry and pharmaceutical industrial field, etc. UHC series

magnetic float level transmitter is mounted on side of vessels,

while UQC series magnetic ball float level transmitter is

mounted on the top of vessels, especially for the

measurement of the underground storage tanks.

Operation principle

UHC series magnetic float level transmitter and UQC series

magnetic ball float level transmitter are composed of body part

and local indicator. UHC series magnetic float level transmitter

is mounted and connected on the side of vessels. When the float

moves up and down with the level (interface) changing, the

magnet steel inside float drives the magnetic flakes inside of the

indicator to roll over. All the magnetic flakes are coated with

red one side and white another side (liquid is red, air is white).

The continuous red or white zone can clearly indicate actual

level or interface inside of vessels. While UQC series magnetic

ball float level transmitter is mounted on the top of vessels.

With the level or interface changing, the ball float will move up

and down and drive the magnetic connecting rod going up and

down. The magnet steel inside of the connecting rod drives the

magnetic flakes inside of the indicator to roll over. All the

magnetic flakes are coated with red one side and white another

side (liquid is red, air is white). The continuous red or white

zone can clearly indicate actual level or interface inside of

vessels. If equip with remote transducer and upper/lower alarms,

the UHC, UQC series transmitters can realize remotely

transmitting the level signal and automatically controlling.

UQZ Magnetic Ball Float Level Transmitter

Summary

UQZ series magnetic ball float level transmitter has the

magnetic ball float as its measuring element. Through

magnetic coupling principle, the ball makes the resistance

inside the transducer changes lineally. Then the transducer

converts the resistance changes into 4-20mA standard

current output signal. In this way, the transmitter can fulfill

automatically level checking, controlling and recording. It

is suitable for level measurement for different kinds of

atmospheric vessels and pressurized containers in

petroleum, chemical, power, light industry and

pharmaceutical industrial field. It is ideal level instrument

for underground storage tanks. It can be classified into side

mounted type and top mounted type.

Operation principle

UQZ series magnetic ball float level transmitter is

composed of two parts: liquid level sensor and current

converter. The ball float moves with level synchronously to

control the reed switch to be on or off so as to make the

inner resistance change linearly. Then the current converter

transforms the resistance value change into 4-20mA

standard current signals and transmits them out.

MLT series Magnetostrictive Level Transmitter Summary

MLT magnetostrictive level transmitters is designed according to the magnetostrictive principle, which is a highly accurate, respond fast, good reliability, long life, smart structure level measuring instrument. Magnetostrictive level transmitter adopts two-wire system 4-20mA with HART for level measuring, which is widely used in the applications of petroleum, chemical, food , metallurgy and so on.

Operation principle

Magnetostrictive sensor is the heart of magnetostrictive level transmitter, while the core component of the sensor ( magnetostrictive line) is rare earth giant magnetostrictive material which enjoys the reputation of " black gold" in the modern industrial world. It has a high strain, electric (magnetic) mechanical wave conversion ability, etc., and can convert the small change of magnetic vector into a mechanical wave. The operating principle is as follows: Within the sensing tube there is a taut magnetostrictive line (1), along which the sensor circuit emits current pulse (2), resulting in a ring of magnetic field around the magnetostrictive line (3). There is a couple of permanent magnet steel in the level float (4), which magnetizes the magnetostrictive line in axial. The superposition of two magnetic fields produces a torsion pulse in the position of the float (5), which reaches both ends along the magnetostrictive line, one end to the sensing tube top accepted by the sensor and the other end to the bottom of the sensing tube. The time difference between emitting and receiving can be calculated to determine the position of the float.

GWLF Guided Wave Radar Level (Interface) Transmitter

Summary

GWLF can be used for measuring level or interface with

4-20mA standard current signal output. The measuring

accuracy is not affected by change of density or dielectric

constant of medium (in the setting range). It is easy operating

and maintenance. It only needs to be entered configuration

data into the instrument and no need to change the liquid

level at field. So, GWLF is a new type of level (interface)

measuring instrument.

Operation principle

GWLF consists of the controller (In Figure1), the probe and

the measuring chamber (this part only for side mounted). Its

operation principle is time domain reflectometry that

electromagnetic wave propagating along the wave guide rod

down, when the wave meets the mutation of a dielectric

constant of medium, it will be reflected back. High-speed

time acquisition circuit will measure liquid level accurately.

The dielectric of the measured medium should be 1.4 at least

(such as Butane).Boiling, fluctuations, overfall and even the

mixing blade have less affection when measuring liquid level.

Measurement data have nothing to do with working condition (process temperature, process

pressure, medium density). As shown in figure 2.

When need to meausre level, below requirements are requested:①.Upper medium thickness

can’t be less than 60mm; ②. The dielectric constant of upper medium should between 1.4

and 2.3; ③. Lower medium dielectric constant should be 10 times of upper medium dielectric

constant. As shown in figure 3.

UQK(S)-100 Float Level Controller

Summary UQK(S)-100 float level controller is suitable for fluid level or interface controlling and alarm for different kinds of open or pressurized vessels in production process in petroleum, chemical, power, paper-making and food industries, etc.

Structure principle UQK(S)-100 float level controller belongs to two position level instrument. It consists of float and contact part. When the level changes, the float position changes correspondingly and makes the magnetic steel at the end of the ball rod of float up and down. According to magnetic repulsion principle, the magnetic steel mounted in contact part goes up and down at reverse direction. Moving contact switches on or off with the fixed contacts 1-1 and 2-2 to make alarm system alarm or pump start and stop. The controllers can be classified into common type and self-checking type by structure. For the self-checking float level controller, it can be checked by pressing outside handle to test the float acting or not during the operation. So, it is very convenient for adjustment and service. UQK(S)-105 float level controller can operate in draw off pipe of tank, is suitable for inner floating roof tank.

UTK Displacer Level Controller

Summary

Measuring element of UTK displacer level controller is ball float or displacer, measuring element is connected with magnet tube. When level raised, magnet tube moves up and enters external magnetic field. Through magnet induction effect or magnet coupling effect, the magnet controlling switch or offset magnet steel is pulled and makes switch contact on or off. When level goes down, the magnet tube moves down and goes out off the external magnet field. Then the magnetic controlling switch backs to the original state or the offset magnet steel goes down back to new balance position under the action of self-weight, then makes switch contact on or off. In this way, it realizes level controlling and alarming.

LBTC Positive Displacement Rotary Vane Flow Meter

Summary

LBTC positive displacement rotary vane flow meter belongs to positive displacement meter and is one of

the most accurate measuring meters for measuring liquid of modern industry. The flow meter has stable

performance and is insensitive to flow state change of upstream medium and change of medium viscosity.

It has high measuring accuracy，good applicability and long life. Now it has widely used for every field

such as process control of modern industry and trade settlement, etc.

Operation Principle

There are two or three couples of rotary vanes, they

slide radially along grooves in the barrel-type rotor. With

the action of flowing pressurized fluid, pushing the rotary

vanes and the rotor rotates around its axis. Rotary vanes

continuously divide the flowing fluid into an individual

volume, using drive gear and counting mechanism

calculate and indicate the total delivery of the fluid. The

process as follows: when the rotary vanes are at the state

as figure 1.1,vane A and D stretch out from the rotor and

contact the inwall of measuring chamber while vane B

and C retract back completely into rotor. With the fluid

entering into the meter, it pushes the vanes and the rotor

rotating clockwise. When the rotor and vanes run 1/8

circle, the vanes stop at the position as shown in figure 1.2, vane A stretches completely, vane D begins to retract

back, vane C is still in completely contraction state, while vane B begins to stretch out. When the rotor and the

vanes run a 1/4 circle, the vanes are in the positions as shown in figure 1.3. The vane A and B both completely

stretch out, the space which is composed of the two vanes, rotor, the meter case bore, the upper cover and lower

cover is full of measuring fluid. When the rotor and the vanes are in the position as shown in figure 1.4, the fluid

in the space begins to be released with the vane A withdrawing gradually. Meanwhile, the vane C begins to stretch

out, another new exactly measuring fluid volume between the vane B and C begins to form gradually. So when

four vanes rotate around the whole circle is 4 times of volume. ( the meter has three pairs vanes, 6 space volumes

will be drained) it realizes fluid measurement.

2. Installation requirements We suggest LBTC positive displacement rotary vane flow meter should install according to installation instruction

as shown in figure 5.

2.1 Connection pipe of LBTC positive displacement rotary vane flow meter should be the same diameter and axis

as inlet and exit of flow meter, can not have projections on pipe wall. Connection pipe near flow meter can’t

have obvious transformation, and minimizing the impact on flow meter due to expansion and contraction of

pipeline.

2.2 Installing flow meter on new pipe, to avoid sundries in pipe along with the fluid entering into flow meter that

will cause damage, you can use short pipe instead of flow meter. After cleaning or purging the pipe, install the

flow meter. Don’t let scavenging air pass bulk.

2.3 You should take off the sealing-capping of connecting flange on flow meter before installation, if impurity and

gas content in fluid is high, we suggest installing filter、gas eliminator or LPXG before flow meter, filter mesh

should be used as following ranges: flow meter of DN20-50 should use 20mesh, DN80-150 should use

15mesh, DN200-300 should use 10mesh.

2.4 The flow meter should be installed horizontally on main pipe ,generally the slant angle should be no more than

15°,to make sure clearance of rotary vane of flow meter is equalizing and measurement is accurate.

2.5 Direction of arrow on flow meter should be the same as flow direction of fluid when installing, flow meter and

straight pipe of both sides should be on coaxial line.

2.6 Flow throttle valve and switch valve installed on pipe work reliably. For observation and inspection

conveniently, abscission of bypass pipe can use closing device which is composed of two switch valves in

series, there is a small-bore leak valve on the short connecting pipe between two valves, you can inspect the

cutting capacity conveniently.

2.7 Use strictly according to range on the nameplate of flow meter: all of max. flow, operating pressure, operating

temperature, fluid viscosity can’t exceed specialized range on the nameplate of flow meter.

2.8 When using the flow meter, you should open the valve slowly and increase the flow gradually until reaching

needed flow, but can’t exceed the max. flow limited by nameplate on flow meter.

2.9 The flow meter should be maintained periodically, main content of maintenance as follows:

a) Inspecting whether the flow range exceeds max. flow on the nameplate;

b) Observing whether there is regular noise in the housing of operating flow meter, and whether there is bigger

impurity and foreign matter entering flow meter.

c) After the parts replacement, you need to re-calibrate.

d) The flow meter in normally using should be calibrated regularly according to industry stipulation.

e) When using mechanical integrating instrument, you should inject lubricant regularly.

The flowmeter is suitable for petrochemical, chemical, chemical fiber, traffic, commerce, food, medicine, health care and other industrial departments of commerce measurement control and engineering management.

Principle of Operating

LZZ -S double rotor flowmeter consists of flow transmitter and counter. The main part of the transmitter is composed of measuring room equipped with a pair of special tooth profile of helical rotor and seal coupling. Counting mechanism contains retarding mechanism, precision adjusting mechanism, counter for print wheel accumulation and electrical transmitter, etc.

Measuring room mainly composed of a pair of special rotor and cover seal cavity as flow measurement units. Rotor powered by the differential pressure of import and export of flowmeter so that send the inlet liquid to the exit after passing the sealing cavity measurement. The amount of liquid through seal chamber every turn is eight times of the picture, sealing coupling transfers the total rotation of the rotor and rotating speed to the counting mechanism, and a pointer to display and print wheel accumulation, then you can know the total amount of liquid passing by the pipe. You can also install transmitter in counting mechanism, namely become the flowmeter which can output signal, the transmitter matches with our company’s electric display instrument, can also realize remote transmission (quantitative, accumulated, moments, etc) automatic measurement and control. You can see the instruction in the display instrument classification.

3 Double rotor flowmeter with warm jacket In order to facilitate transporting and measuring flow for the medium that is easy to freeze under normal temperature or condense, crystallize, usually need to heat medium in the system pipe, and melt the medium and hold its temperature. But due to the double rotor flowmeter installation does not allow directly access to the steam (purpose is to prevent damage meter), therefore we design the flowmeter with warm jacket. The flowmeter housing add warm jacket outside, to melt solidified medium in the flowmeter, you can use hot water, hot oil or below 200 steam flux into the warm jacket and keep certain temperature so that make sure the flowmeter keep moving. The filter installed on double rotor flowmeter can also be adopted with the structure of warm jacket. The inlet and outlet of warm jacket usually is designed by DN15 diameter flange, or on special request. The warm jacket nominal pressure is 0.5Mpa, or on special request.

2 Installation and application

2.1 The filter should be installed in front of the flowmeter, their housing’s arrow directions are

the same.

2.2 When the measured liquid containing gas, the gas separator should be installed in front of

WWW.DDTOP.COM

113

flowmeter.

2.3 Under the condition of correct installation of the flow meter, if it is not easy to see reading,

counter can be turned to 180 ° or 90 °.

2.4 Push the rotor a few times with a wooden stick from the exit before installing a new

flowmeter, if the rotor does not move, you can soak with gasoline (to avoid deposits after factory

check).

2.5 Throttle valve should be installed in the inlet of the flow meter, on-off valve installed in the

exit, When using on-off valve needs a slow start, don't suddenly open valve.

2.6 It is forbidden to use steam sweep line through the flowmeter.

2.7 In continuous occasion, flowmeter must add by-pass pipe.

2.8 The pipe shall be flush before flowmeter installation, when flushing straight pipe (replace

flow meter location) to prevent welding slag, debris into the meter.

2.9 It is forbidden to check meter composed of carbon steel material by water.

2.10 When flow meter measuring flow, the value of flow shall not exceed the range of flow

range. Flow meter working in 40-80% of maximum flow is suitable.

3 Error calculation and adjustment

3.1 The basic error of flowmeter is calculated by the verification flow point of all measured

values according to the following formula: (volume)

E=(Vm－V)/V×100%

E－－The error of flowmeter(generally refers to accumulative error) take two significant figures.

WWW.DDTOP.COM

114

Vm－－Flowmeter measuring values(indicating value)

V－－After meter is corrected, flow standard device measuring value ( the actual value)

From the basic formula of error, when Vm is greater than V, The basic error of flowmeter

is“+”, it indicates flowmeter going fast.

From the basic formula of error, when Vm is less than V, The basic error of flowmeter is“-”, it

indicates flowmeter going slow.

In order to make the flowmeter errors within a basic error limits, often need to adjust the error.

By replacing a pair of adjusting gear (tooth) in counter changes the mechanical transmission

speed ratio, so that the flow meter’s indicating value gets adjusted.

Error adjustment can't change features of the flowmeter, only make its features curve

artificially in a new coordinate. In general, in the prescribed (or actual use) flow range, the basic

error range of the maximum and minimum flow check point is not more than the precision of the

basic error limits, all can realize flowmeter basic error qualified by adjusting error.

For flow meter has been used, usually use the original adjusting gear checking error, and then

adjusting error according to the error of the specific situation.

3.2 Double rotor flowmeter error adjusting method (error adjustment instructions)

3.2.1 Common error adjusting method:

3.2.1.1 In designing the standard of the double gear is 38/35, During inspection, if you find the

meter is going faster, namely appear error (+),such as +1.02-+0.3,the gear should be changed

38/35 into 41/38, at this time original point of the error curve moves up from 38/35 gear

corresponding to zero to 41/38 gear to the location of + 0.63 (see table), so error curve in a new

coordinate, and the error of flowmeter has been adjusted in the range of + 0.39 ~ ﹣0.33,and

satisfy the qualified requirements(see figure 1).

3.2.1.2When the flowmeter is working, due to the

different working conditions and changes, the error

usually changes and it may exceed the maximium error,

if only the error range is less than 1%, generally can be

transferred to qualified, for example, instrument error

drops to 0.7 ~ + 0.2, and need to change the double

gear, at first you should know that how many gear

teeth the double gear has. If the double gear is38/35,

adjust according to the above of the first method. If the

double gear is38/35, then take the error+ 0.63

corresponding to gear as zero(the origin of

coordinates).Now the 41/38 gear should be changed

into the double gear of 41/37, error can be adjusted to

the range of﹣0.5-﹢0.4 that make sure qualified (see figure 2).

3.2.1.3 The specific method of calibrating and adjusting double rotor flowmeter of class 0.2

should be according to the national metrological verification procedures JJG667-1997 "liquid

volumetric flowmeter verification regulation".

3.2.2 The error adjustment method of GF3 external precision regulator

GF3 is a kind of external precision regulator, when error adjusting, do not need to remove the

governor and can be directly adjusted in the external, the operation is convenient, easy and

WWW.DDTOP.COM

115

WWW.DDTOP.COM

116

accurate.

Example for adjustment method:

When there is + 0.63 ~ 0.67% error in calibration flowmeter, after unscrewing the lid of the

external regulator, you can see the left and right knobs, adjust error according to the surface of

the scale of the external precision regulator. Coarse adjustment specification is 0.45% per cell,

adjusting the coarse gear one cell in the direction of negative, that is﹣0.45%,it can make the

original error theory adjusted + 0.63 ~ + 0.67% to + 0.18 ~ + 0.22%, then you can adjust fine

tuning gear two cell in the direction of negative. The value of adjustment is 0.05×2=0.10%, then

the adjustment is from + 0.18 ~ + 0.22% to + 0.08 ~ + 0.12, achieved the best error value.

Suggest high accuracy (class 0.2) flowmeter configuring GF3 is preferred.

LG Series Orifice Flow Measurement Throttle Device

Summary

Throttle device is the most historic and most extensively

used flow measurement instrument. Its features are simple

structure, easy installation, stable performance and high

accuracy, etc merits. It can be used for flow measurement

for liquid, steam and gas in modern industries. There are

many kinds of throttle devices with a whole variety (being

conformability with Standard GB/T2624-2006, Standard

ISO5167-1-20031, Standard BS1042-1989 and Standard

ASME) that are manufactured with advanced calculation

methods and precise manufacturing means. They are

applied extensively in petroleum, chemical, power, light

industry, water supply field, gas transmission field etc. Orifice Throttling Device

Principle of operation

WWW.DDTOP.COM 131

A throttle element (like throttle orifice, throttle nozzle, etc)

is installed in a pipe that is full of one way flowing

continuous fluid. When the fluid passes the throttling

orifice of the throttling element, the fluid stream forms

local shrink. Then the velocity increases, so does the kinetic

energy, the static pressure decreases. So, there is a

differential static pressure from the fore and the rear of the

throttle element, i.e. P=P1-P2. If the area of the throttle

orifice is F, the mass flow of the fluid is qm, the volume flow

is qv the density is ρ, then according to the flow continuity

law and Bernoulli equation, the following mathematical

relations between differential pressure and fluid flow can be

derived:

Wenturi Tube Throttling Device

qm = αF or qv = αF

“α” is flow coefficient. According to the above equation, if

the area of the throttle orifice and fluid density are constant,

flow has direct ratio with square root of differential pressure.

That is to say, if you have the differential pressure value, then

you can calculate the flow value. Throttle device can

measuring fluid flow just according to this principle.

LGXL Throttling Orifice Device

Summary

Throttling orifice is suitable for automatic control, piping and other professional situations in the

engineering design, here are several occasions which are frequently used ：

a. It required that fluid with small flow continuously passing it, such as analysis on the sampling

pipeline, pump flush pipeline, hot standby pump bypass line and so on, can set the current

limit orifice to implement;

b. It required fluid step-down occasions, such as setting limit flow orifice after the control valve

to minimize the pressure drop on the valve, reduce the noise of the valve, reduce the wear of

valve seat and valve element, avoid liquid flash vaporization and cavitation phenomenon

behind the valve, prolong the service life of the valve; Fluid requires step-down, you can use

the current limit orifice plate to step-down for the application that step-down precision is not

high;

c. Application required fluid step-down and current limiting, such as setting the current limit

orifice plate on bypass control valve, in order to prevent the operation of the bypass, liquid

pressure drops too fast or causes danger such as liquid evacuated. For piping emptying

system, when big pressure drops and produces a lot of noise, you can use current-limiting

orifice plate to reduce the noise, to improve the production environment.

LGV V Internal Cone Flow Meter

Summary LGV V type internal cone flowmeter is the second generation of inner cone flowmeter, is a kind of

high performance differential pressure type flow measuring instrument and it’s Dandong Top

Electronics Instrument (Group) Co.,Ltd. and Tianjin University cooperative development. The

unique support body and variable angle designed, can make it under the conditions of short straight

pipe, the metallurgy, chemical industry, chemical fertilizer, chemical fiber, oil, natural gas, electric,

hydraulic, and other industrial enterprises in various mediums such as gas, liquid and steam flow

measurement. It has strong cone, short straight pipe, high measurement precision, wide range ratio,

small pressure loss and low cost of installation and other characteristics, is a breakthrough in the

field of flow sensor technology in recent years, it makes up for the orifice, nozzle, venturi tube and

cone to correct and rectify all kinds of the irregular flow distortion of upstream, which realize forming

regular flow of flow measurement area. So it takes only a short straight pipe can obtain accurate

measurements. Greatly facilitate the users.

3.6. Low pressure loss, good for energy saving

V type internal cone flow meter’s structure feature is streamline throttle device, it is low pressure loss

(about 1/3 of the orifice plate), huge advantage in measuring low pressure & high flow rate fluid.

Meanwhile, low pressure loss means low energy cost, so it can satisfy the energy saving request of

enterprise.

3.7. Long life and stable performance:

The boundary layer effect of V type internal cone flow meter is its specific structure which will protect

3 Installation Requirements

3.1 V type internal cone flow meter in a certain applicable range, make sure it is in line with the

process working conditions before installation (Flow, pressure, temperature, etc)

3.2 V type internal cone flow meter is installed in the pipeline, the flange end face is perpendicular

to the pipe axis, to allow maximum not vertical degree ±1°.

3.3 The gasket installation shall not highlight the internal pipe wall, otherwise it will cause very big

measurement error.

3.4 All flow adjusting valve, it is better to install behind the throttling component and outside a

minimum length of straight pipe.

3.5 V type internal cone flow meter installation must be in pipeline cleaning after scavenging.

3.6 V type internal cone flow meter need to meet the specified requirements about the installation

of the straight pipe, otherwise it will affect measurement accuracy.

3.7 If installed in a vertical line, measured medium is liquid, it must flow from bottom to top.

3.8 Requirement about the ahead and behind straight pipe:

Flow resistance upstream downstream

One elbow 3D 2D

Two elbow 3D 2D

Tee section head 3D 2D

Butterfly Valve 5D 3D

ball valve 3D 2D

reducing pipe 3D 2D

expanding pipe 4D 3D
