Measuring principle

Ceramic measuring diaphragms used for PMD 70 and FMD 76

The ceramic measuring cell is based on the principle of a plate capacitor with an electrode on (1) and a movable

electrode on the interior of the diaphragm (3). Standard silicone oil or mineral oil filling oils for this measuring

cell.

A differential pressure (p1 ≠ p2) causes a corresponding deflection of both diaphragms. Both capacitance values

are converted and are fed to the microprocessor of the transmitter as a digital signal.

Advantages:

• Self-monitoring for diaphragm break or oil loss (constant comparison of the measured temperature with a

temperature calculated from the capacitance values)

• Extremely high resistance to aggressive media

• Suitable for vacuums up to 0.02 psiabs (1 mbarabs)• Metal-free versions available

• Secondary process barrier for enhanced mechanical integrity

Metallic measuring diaphragms used for PMD 75, FMD 77 and FMD 78

The separating diaphragms (3/9) are deflected on both sides by the acting pressures. A filling oil (4/8) transfers

the pressure to a resistance circuit bridge (semi-conductor technology). The change due to differential pressure

of the bridge output voltage is measured and further processed.

Advantages:

• Standard operating pressures: 2320 psi and 6100 psi (160 bar and 420 bar)

• High long-term stability

• Very high single-sided overload resistance

• Secondary process barrier for enhanced mechanical integrity

Q Flow

∆p Differential pressure, ∆p = p1 – p2

Your benefits

• Choice of four flow modes of operation: volume flow, norm volume flow (European norm conditions),

standard volume flow (American standard conditions) and mass flow.

• Choice of flow units with automatic unit conversion.

• User-specified custom measuring units.

• Low flow cut off: when activated, this function suppresses small flows which can lead to large fluctuations

in the measured value.

• Contains two totalizers as standard. One totalizer is user-resettable.

• The totalizing mode and unit can be individually set for each totalizer. This allows independent daily and

Display module (optional) A 4-line liquid crystal display (LCD) is used for display and operation. The display module shows measured

values, dialog text as well as fault and notice messages in plain text, thereby supporting the user in every stage

of operation.

Functions:

• 8-digit measured value display including sign and decimal point, bargraph for current display

• Simple and complete menu guidance due to separation of the parameters into three levels (blocks, groups

and functions)

• Each parameter is given a 3-digit ID number for easy navigation.

• Option for configuring the display according to individual requirements and desires, such as language,

alternating display, display of other measured values such as sensor temperature, contrast setting

• Comprehensive diagnostic functions (fault and warning message, peak-hold indicators, etc.)

• 4 to 20 mA HART: rapid and safe commissioning with the Quick Setup menus


Operating elements The operating buttons are located either under the protective cap on the exterior of the device or inside on the

electronic insert, depending on configuration of transmitter.

Operating conditions (installation)

General installation instructions • For FMD 77 and FMD 78: See page 50 ff, "Installation instructions, Diaphragm seal systems" section.

• The position-dependent zero shift can be corrected directly at the device via operating keys, even in

hazardous areas. Diaphragm seals also shift the zero point, depending on the installation position (→ See also

page 50 ff, "Installation instructions, Diaphragm seal systems").

• The housing of the Deltabar S can be rotated up to 380°. → See also page 22, section "Rotating the housing".

• Endress+Hauser offers a mounting bracket for installing on pipes or walls. → See also page 22, section

"Wall- and pipe-mounting".

• When measuring in media with solid proportions, such as dirty liquids, installing separators and drain valves

is useful for capturing and removing sediment.

• Using a three-valve or five-valve manifold allows for easy commissioning, installation and maintenance

without interrupting the process.

• General recommendations for the impulse piping can be found in DIN 19210 "Methods for measurement of

fluid flow; differential piping for flow measurement devices" or the corresponding national or international

standards.

• Install the impulse piping with a continuous gradient of at least 10%.

• When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is used, e.g. by using

pipe heat tracing.

Measuring arrangement Flow measurement

• The PMD 70 and PMD 75 are best suited to flow measurement.

• Measuring arrangement for gases: Mount device above the measuring point.

• Measuring arrangement for liquids and steam: Mount device below tapping point.

• For flow measurement in steam, mount the condensate traps at the same level as the tapping point and at

the same distance from Deltabar S.

Level measurement

• PMD 70, PMD 75, FMD 76 and FMD 77 are best suited to level measurement in open tanks. All Deltabar

S devices are suitable for level measurement in closed tanks.

Measuring arrangement level measurement in open tanks

• PMD 70, PMD 75: Mount device below the lower measuring connection. The negative side is open to

atmosphere pressure.

• FMD 76, FMD 77: Mount device directly on the tank or with shut-off valve. The negative side is open to

atmospheric pressure.

Measuring arrangement level measurement in closed tanks and closed tanks with static pressure

• PMD 70, PMD 75: Mount device below the lower measuring connection. Always connect the negative side

above the maximum level.

• FMD 76, FMD 77: Mount device directy on the tank. Always connect the negative side above the maximum

level.

• In the case of level measurement in closed tanks with static pressure, a condensate trap ensures pressure

which remains constant on the minus side.

Pressure measurement

• The PMD 70 and PMD 75 are best suited to differential pressure measurement.

• Measuring arrangement for gases: Mount device above the measuring point.

• Measuring arrangement for liquids and steam: Mount device below tapping point.

• For differential pressure measurement in steam, mount the condensate traps at the same level as the tapping

point and at the same distance from Deltabar S.

Oxygen applications Oxygen and other gases can react explosively to oils, grease and plastics, such that, among other things, the

following precautions must be taken:

– All components of the system, such as measuring devices, must be cleaned in accordance with standard

requirements (BAM, DIN 19247, CGA-4.1-1996, AGA G93-96).

– Dependent on the materials used, maximum temperature and a maximum pressure must not be exceeded.

The devices suitable for oxygen applications are listed in the following table with the specifications Tmax and

pmax.

Ultra pure gas applications Endress+Hauser also offers degreased devices for special applications, such as ultra pure gas.

No special restrictions regarding the process conditions apply to these devices.

→ See also page 53 ff, PMD 70 and PMD 75: feature 80 "Gasket material", FMD 76 and FMD 77: feature 70

"Process connection low-pressure side, material, seal".

Diaphragms for materials with

hydrogen build-up (Rhodium-

Gold coating)

When materials are used in which hydrogen build-up occurs, hydrogen atoms can diffuse through the metals

of the sensor. This can lead to corrupt measurement results.

Endress+Hauser offers diaphragms with Rhodium-Gold coating for this application.

→ See also page 56 "Ordering information PMD 75", page 62 "Ordering information FMD 77" or page 65

"Ordering information FMD 78", feature 60 "Material diaphragm".

Planning instructions, diaphragm seal systems

Applications Diaphragm seal systems should be used if the process media and the device should be separated. Diaphragm

seal systems offer clear advantages in the following instances:

• In the case of high process temperatures (→ See also page 24, section "Process temperature limits".)

• In the case of process media that crystallize

• In the case of corrosive process media or process media with solids content

• In the case of heterogeneous and fibrous process media

• If measuring point cleaning is necessary

• The measuring point is exposed to vibration.

• Installation sites that are difficult to access (e.g. better view of display).

Design and operation mode Diaphragm seals separate the measuring system and the process medium.

A diaphragm seal system consists of:

• A diaphragm seal in a one-sided system, e.g. FMD 77 or two diaphragm seals, in a two-sided system, e.g.

FMD 78

• Capillary tube

• Fill fluid and

• A differential pressure transmitter.

The process pressure acts via the diaphragm seal membrane on the liquid-filled system, which transfers the

process pressure via the capillary tube onto the sensor of the differential pressure transmitter.

Endress+Hauser delivers all diaphragm seal systems as welded versions. The system is hermetically sealed,

which ensures the highest reliability.

Note!

The correlations between the individual diaphragm seal components are presented in the following section.

For further information and comprehensive diaphragm seal system designs, please contact Endress+Hauser

Sales.

Diaphragm seal

The diaphragm seal determines the application range of the system by

• the diaphragm diameter

• the diaphragm: stiffness and materials of construction

• the design (oil volume).

Diaphragm diameter

The larger the diaphragm diameter (less stiffness), the smaller the temperature effect on the measurement

result.

Note: When feasible, select diaphragm seals with a nominal diameter of ≥ 3" (DN 80), to reduce temperature

effects within acceptable limits.

Diaphragm stiffness

The stiffness is dependent on the diaphragm diameter, the material, any available coating and on the diaphragm

thickness and shape. The diaphragm thickness and the shape are defined by the limits of the process connection

construction. The stiffness of a diaphragm seal membrane influences the temperature operating range and the

measuring error caused by temperature effects.

Capillary

Diaphragm seals are used with the following capillary internal diameters as standard:

• ≤ 2" (DN 50): 0.04" (1 mm)

• > 2" (DN 50): 0.08" (2 mm)

The capillary tube influences the TK zero point, the ambient temperature operating range and the response time

of a diaphragm seal system as a result of its length and internal diameter.

→ See also page 47 ff, sections "Influence of the temperature on the zero point for diaphragm seal systems", "Ambient temperature range" and "Response time".

→ Observe the installation instructions regarding capillary tubes. See page 50 ff, section "Installation instruc-tions".

Deltabar S

46 Endress+Hauser

Filling oil

When selecting the filling oil, fluid and ambient temperature as well as the operating pressure are of crucial

importance. Pay attention to the temperatures and pressures during commissioning and cleaning. A further

selection criterion is the compatibility of the filling oil with the requirements of the process medium. For this

reason, only filling oils that are non-toxic are used in the food industry, such as vegetable oil or silicone oil.

→ See also the following section "Diaphragm seal filling oils".

The filling oil used influences the TK zero point and the temperature operating range of a diaphragm seal system

and the response time. → See also page 47 ff, sections "Influence of the temperature on the zero point for diaphragm seal systems" and "Response time".

Differential pressure transmitter

The differential pressure transmitter influences the temperature operating range, the TK zero point and the

response time as a result of the volume of its side flange and as a result of its volume change. The volume

change is the volume that has to be shifted to pass through the complete measuring range.

Differential pressure transmitters from Endress+Hauser are optimized with regard to minimum volume change

and side flange.

Influence of the temperature on

the zero point for diaphragm

seal systems

A temperature change results in a volume change of the filling oil. The volume change is dependent on the

coefficient of thermal expansion of the filling oil and on the volume of the filling oil at calibration temperature

(+77°F/+25°C , range: +69.8 to 91.4°F/+21 to +33°C). → See also page 46, section "Diaphragm seal filling

oils".

For example, the filling oil expands in the event of a temperature increase. The additional volume presses

against the diaphragm seal membrane. The stiffer a diaphragm is, the greater its return force, which counteracts

a volume change and acts on the measuring cell together with the operating pressure, thus shifting the zero

point. For the "TK Process", see page 37 ff, section "Process connections FMD 78".

The following diagrams display the temperature coefficient "TK Ambient" dependent on the capillary length.

The following application is displayed: capillary temperature and transmitter temperature (ambient

temperature) change, the process temperature corresponds to the calibration temperature.

The temperature coefficients obtained from the diagrams apply to silicone oil and the membrane material AISI

316L. For other filling oils, these temperature coefficients must be multiplied by the TK correction factor of the

corresponding filling oil. For the TK correction factors, see page 46, section "Diaphragm seal filling oils".


Example for:

– Diaphragm seal versions "B5, EN/DIN Flange DN 80 PN 10-40 B1, AISI 316L"

– Capillary length: 16 ft (5 m)

– Ambient temperature, capillary/transmitter: 113°F (45°C)

– Filling oil: silicone oil

1. Select characteristic curve type for the diaphragm seal versions "B5" in accordance with the following

table.

Result: characteristic curve type 2

2. Obtain value for TK Ambient from the diagram.

Result: 1.4 mbar/10 K

3. Tambient – Tcalibration = 45°C – 25°C = 20°C ⇒ 1.4 mbar/10 K • 20 K = 2.8 mbar

Result: In this application, the zero point is shifted by 2.8 mbar.

Note!

The influence of temperature on the zero point can be corrected with position calibration.

Ambient temperature range The filling oil, capillary length, capillary internal diameter and the diaphragm diameter of the diaphragm seal

have an influence on the ambient temperature operating range of a diaphragm seal system.

Note!

For further information and comprehensive diaphragm seal system designs, please see your local

Endress+Hauser Sales Center.

Response time The viscosity of the filling oil, the capillary length and the capillary internal diameter influence the frictional

resistance. The greater the frictional resistance, the longer the response time.

Furthermore, the volume change of the measuring cell influences the response time. The lower the

volume change of the measuring cell is, the less filling oil has to be shifted in the diaphragm seal system.

The following diagram shows typical response times (T90%) for the various filling oils dependent on the

measuring cell and the capillary internal diameter. The values given are in seconds per metre of capillary length

and must be multiplied by the actual length of the capillary. The rise time of the transmitter must also be taken

into consideration.

Installation instructions Instructions for diaphragm seal systems

• The diaphragm seal together with the transmitter form a closed, calibrated system, which is filled through

ports in the diaphragm seal and in the measuring system of the transmitter. These ports are sealed and must

not be opened.

• When selecting the measuring cell, observe the zero shift resulting from the hydrostatic pressure of the filling

fluid columns in the capillaries. (→ See the following illustration).

• When using a mounting bracket, sufficient strain relief must be allowed in order to prevent the capillary from

exceeding a bending radius ≥ 4" / 100 mm.

• The temperature and length of both capillaries should be the same when using two-sided diaphragm seal

systems.

Installation instructions

In order to obtain more precise measurement results and to avoid a device failure, mount the capillaries as

follows:

• vibration-free (in order to avoid additional pressure fluctuations)

• not in the vicinity of heating or cooling lines

• insulate at colder or warmer ambient temperatures

• with a bending radius of ≥ 4" (100 mm).

Vacuum applications

For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter below the

lower diaphragm seal. A vacuum load of the diaphragm seal caused by the presence of filling oil in the capillaries

is hereby prevented.

When the pressure transmitter is mounted above the lower diaphragm seal, the maximum height difference

H1 in accordance with the following illustration on the left must not be exceeded. The maximum height

difference is dependent on the density of the filling oil and the minimum expected pressure that is permitted

to occur at the diaphragm seal on the positive side (empty tank), see the following illustration, on the right.

Pressure on the negative side of the differential pressure transmitter (p–) when the tank is empty (min. level)

Pressure on the positive side of the differential pressure transmitter (P+) when the tank is empty (min. level)

Differential pressure at the transmitter (∆pTransmitter) when the tank is empty

Result:

If the tank were full, a differential pressure of –51.80 mbar would be present at the differential pressure transmitter. When

the tank is empty, a differential pressure of –149.90 mbar is present. Therefore, a 500 mbar measuring cell is required for

this application.
