Float fl ow meters DFM 165 - DFM 350

ASV fl oat fl ow meters are available for many

fl ow ranges from 3 to 50.000 l/h. The tried

and tested design is being used in many

applications from water treatment to heavy

chemical industry. Based on a special confi -

guration software special scales for almost

every liquid or gaseous fl uid can be supplied.

All ASV fl oat fl ow meters come with an integ-

rated assembly mounting rail for the fi tting of

position indicators and can be supplied with

corresponding magnetic fl oats. Next to the

optical display the DFM can be used as part of

more complex control systems.

Flow data sensors ZE 3075

The ZE3075 consists of a reed switch chain

which is activated by a magnet in the fl oat.

Any movement of the fl oat is detected by

the switches and being transferred into a

continuous 0/4..20mA signal. The unit is

calibrated during commissioning and requires

no further maintenance after that.

Flow data sensors ZE 3000

The ZE 3000 delivers a continuous 0/4..20 mA

signal. This relates to the actual position of

the fl oat inside the meter. The working princi-

pal of the ZE 3000 is based on tri-angulation

between the sensor and the magnet. Because

of this, the ZE 3000 can also read fl oat

positions exceeding the length of the sensor

housing.

Limit switches ZE 950/ZE951

The ZE 950 is a mono-stable limit switch,

which is actuated when the float is directly

in front of the switch. The bistable ZE 951 is

switching between two positions. These are

only changing each time the float passes

the switch, either on the way up or down.

The ZE 951 for that reason is available in

NO (normally open) or NC (normally closed)

version.

For use with fl ow data sensors the fl ow

meters are equipped with magnetic fl oats.

Ultrasonic Sensor UFM

Ultrasonic Sensor UFM

The UFM is able to realise touchless fi lling

level detection. The compact device is able

to monitor a 6 meter range by means of a

continuously sensing, integrated ultrasonic

sensor.

The programming and optical output is done

by means of an optional, plug-in display. As

all ASV display-programmable sensors the

UFM can come with various signal output

options. The connection to a PLC or as direct

controller for other system components can

be done by different current based interfaces

0/4..20mA or as relay-versions. The program-

ming of the device can be comfortably done

be means of many parameters.

Hydrostatic fi lling level

sensor HFT

PPPPPP PVDFPVDFPVDF

Hydrostatic fi lling level sensor HFT

The HFT is detecting the hydrostatic pressure

of a liquid inside a tank with a known geometry

and calculates the corresponding fi lling level.

The sensor is lowered to the bottom of the

tank by a 6 meter FEP-cable and needs to be

calibrated for the fl uid and tank size once.

The special plastic encapsulation of the

sensor allows very precise control even in

aggressive fl uids. Because of the hydrostatic

working principle also foaming liquids can be

safely monitored.

Conductive Limit switch CFP

1.45711.45711.4571

Conductive Limit switch CFP

The conductive sensor CFP has been designed

for use in electrically conductive liquids.

It is available with two or three stainless steel

probes. If the fl uid closes the circuit between

the up to 1 meter long probes the two 24V

relays on the internal output interface are

activated. This simple device is capable of

detecting up to two fi lling levels and therefore

very suitable for min/max actuation.

Level switch NIS

The NIS is capable to detect up to 4 fi lling

levels. The devices operates by means of

diaphragm pressure switches, which reach

into the not pressurised tank via submerging

tubes.

When the fl uid rises in the tube the hydrostatic

pressure of the compressed air in the tube is

actuating the switch. The switching points are

determined by drilling 8 mm vent holes into

the tube 100 mm below the desired switching

point.

BSS

Bistable switch BSS

The BSS is a bistable switch, which gets

actuated by means of a passing magnet.

The system is being used for min/max reading

on tanks and containers. Counterweights or

magnetic fl oats are used for the actuation.

Next to the clear optical indication electric

voltages of 250VAC (30VDC) and currents of

up to 3A can be directly activated. For the BSS

a selection of fl oats, encapsulated magnets

and defl ector rollers are available as accessories.

Leakage and overfi ll prevention

PEPEPEThe operation of containers for water polluting

substances in accordance with the German law

WHG §19 requires the use of approved sensors

to prevent overfi lling and detect leakage.

ASV Stübbe offers an DIBt approved complete

system for electrically conductive liquids. The

system consists of the limit switch SGS and

the leakage probe LS. The processing of the

signals can happen via a PLC or the optional

signalling device SE.

Signalling device SE

The signalling device SE is a controller for

stand-alone systems on individual tanks.

It combines the power supply and signal

processing for the limit switch SGS and the

leakage probe LS and is fi tted with several

230 V relay outputs as well as an optical and

an acoustical warning signal.

Leakage probe LS

The leakage probe LS is a variation of the

limit switch SGS. The purpose of this unit is to

detect leaking liquids in the gap between the

tank and an outer protective container. It is

equipped with a seven meter cable by means

of which the probe can be positioned at the

lowest point of the double walled tank or in

a drip tray. If the capacitive sensor gets in

contact with leaked fl uid a signal is send via

a potential free relay in the same way as from

the SGS sensor.

Limit switch SGS

The limit switch SGS is used to secure that

the maximum fi lling level of a tank can not be

exceeded. Assembly and height adjustment

happen by means of a G2“ threaded fi tting.

When liquid gets in contact with the sensor a

signal is given via a potential free relay.

Pressure relief valve DHV 712-R

Pressure relief valves are used to achieve

and maintain constant operation pressures,

to prevent pressure pulsation and to protect

other pipeline components from pressure

peaks.

The patented pressure relief valve DHV 712-R

contains a high quality spring system

and can be adjusted for pressure ranges

between 0.3 - 10.0 bar. If the pressure on

the inlet side of the valves reaches the set

pressure the valve opens reliably. With

its special piston design the DHV 712-R is

100% back pressure tight and therefore

additionally acts as a non return valve. In

combination with pulsating dosing pumps

the 712-R reaches an outstanding and low-

vibration regulation result.

Pressure relief valve DHV 712

The DHV 712 is equipped with the same back

pressure tight piston design as the 712-R. It is

designed for bigger diameters and available

for different pressure ranges. Like all other

ASV pressure relief valves it can be precisely

adjusted while being pressurised. The high

quality PTFE liner on the actuation diaphragm

makes it the perfect match for a wide range

of aggressive fl uids. With its special piston

design the DHV 712 supplies a constant

operation pressure even in systems with

variable back pressure levels.

Valves from series DHV 725 are diaphragm

actuated pressure relief valves. The seat seal

is a guided piston design. With the extended

actuator bonnet very precise adjustment

over the full pressure range of 0.2 - 10 bar

can be achieved. The high reproducibility of

the actuation pressure and the reliable and

low-vibration regulation behaviour are the key

features of this valve.

Pressure relief valve DHV 715 Pressure relief valve DHV 716

The pressure relief valves DHV 715 and DHV 716

operate along the same working principles

as the DHV 725. They are fi tted with different

spring packages and designed for different

pressure ranges. Because of their different

switching points the valves of series DHV 715,

DHV 716 and DHV 725 cover a wide range of

different applications and pressure settings.

DHV 715 0,2 - 4 bar

The diaphragm operated DHV 718 is a very

reliable and straight forward design, that is

available also for very small diameters. It is

equipped with the same high- quality PTFE-

lined diaphragm as all the other ASV pressure

relief valves. But while it is a diaphragm-only

design it is also suitable for partly particle-

loaded or contaminated fl uids.

a constant output pressure. The downstream

side from the valve is therefore securely pro-

tected from being over-pressurised.

The DMV 750 is one of the biggest available

pressure reducing valves made of thermoplas-

tics. It is equipped with a high-grade PTFE lined

diaphragm. The valve features a very constant

and low vibration regulation behaviour and the

high reproducibility of the set inlet pressure.

The DMV 750 has a working range from

1.0 - 6.0 bar.
