Ceramic process isolating diaphragms used for PMD70 and FMD76

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

Advantages:

• Self-monitoring for process isolating 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 1 mbar

• Metal-free versions available

• Second process barrier (Secondary Containment) for enhanced integrity

P01-xMD7xxxx-03-xx-xx-xx-003

Metallic process isolating diaphragms used for PMD75, FMD77 and FMD78

The process isolating 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 differential-pressuredependent change of the bridge output voltage is measured and further processed.

Advantages:

• Standard operating pressures: 160 bar and 420 bar

• High long-term stability

• Very high single-sided overload resistance

• Second process barrier (Secondary Containment) for enhanced integrity

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 diverse flow units with automatic unit conversion.

• A customised unit can be specified

• 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 can be reset to zero.

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

• With the product family Deltatop, Endress+Hauser is offering a universal and reliable solutions for flow measurement: – Deltatop, the compact, ready-to-use flow measuring unit including differential pressure transmitter

Operating conditions (Installation)

General installation instructions

Measuring arrangement Flow measurement

• The position-dependent zero shift can be corrected directly at the device via operating key, for devices with external operation even in hazardous areas. Diaphragm seals also shift the zero point, depending on the installation position ( ä 64 ff, "Installation instructions").

• The housing of the Deltabar S can be rotated up to 380°.  ä 26, section "Turn the housing".

• Endress+Hauser offers a mounting bracket for installing the device on pipes or walls.  ä 24, 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.

• For FMD77 and FMD78: See page 64 ff, "Installation instructions, Diaphragm seal systems" section.

• The PMD70 and PMD75 are best suited to flow measurement.

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

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

• For flow measurement in vapours, mount the condensate traps at the same level as the same the tapping point and at the same distance from Deltabar S.

Level measurement

• PMD70, PMD75, FMD76 and FMD77 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

• PMD70, PMD75: Mount device below the lower measuring connection. The negative side is open to atmosphere pressure.

• FMD76, FMD77: Mount device direct on the tank. The negative side is open to atmosphere pressure.

Measuring arrangement level measurement in closed tanks and closed tanks with superimposed vapour

• PMD70, PMD75: Mount device below the lower measuring connection. Always connect the negative side above the maximum level.

• FMD76, FMD77: Mount device direct on the tank. Always connect the negative side above the maximum level.

• In the case of level measurement in closed tanks with superimposed vapour, a condensate trap ensures pressure which remains constant on the minus side.

Pressure measurement

• The PMD70 and PMD75 are best suited to differential pressure measurement.

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

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

• For differential pressure measurement in vapour, mount the condensate traps at the same level as the same the tapping point and at the same distance from Deltabar S.

Pressure specifications • The maximum pressure for the measuring device is dependent on the lowest-rated element with regard to

pressure, see the following sections for this: –  ä 8 ff, section "Measuring range" – chapter "Mechanical construction". The MWP (maximum working pressure) is specified on the nameplate. This value refers to a reference temperature of 20°C (68°F) or 100°F for ANSI flanges and may be applied to the device for an unlimited time. Observe pressure-temperature dependency.

• The pressure values permitted at higher temperatures can be found in the following standards: – EN 1092-1: 2001 Tab. 18

– ASME B 16.5a – 1998 Tab. 2-2.2 F316 – ASME B 16.5a – 1998 Tab. 2.3.8 N10276 – JIS B 2220

• For PMD70 and PMD75, the MWP applies for the temperature ranges specified in the "Ambient temperature range" ( ä 27) and "Process temperature limits" ( ä 28) sections.

• The test pressure corresponds to the over pressure limit of the measuring instrument (Over pressure limits OPL = 1.5 x MWP) and may fit only temporally limited, so that no permanent damage develops.

• The Pressure Equipment Directive (EC Directive 97/23/EC) uses the abbreviation "PS". The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring device.

• In the case of sensor range and process connections where the OPL (Over Pressure Limit) of the pressure connection is smaller than the nominal value of the sensor, the device is set at the factory, at the very maximum, to the OPL value of the process connection. If you want to use the entire sensor range, select a process connection with a higher OPL value (1.5 x PN; PN = MWP).

• In oxygen applications, the values for "p

max

and T

for oxygen applications" as per  ä 26, "Oxygen

max

applications" may not be exceeded.

1) With regard to their stability-temperature property, the materials 1.4435 and 1.4404 are grouped together under 13EO

in EN 1092-1 Tab. 18.

The chemical composition of the two materials can be identical.

Note!

• Specifications for the "TK Process" are listed in the following tables. These are typically values. These temperature coefficients apply to silicone oil and the process isolating diaphragm material AISI 316L/

1.4435. For other filling oils, this temperature coefficient must be multiplied by the T

correction factor of

the corresponding filling oil. For the TK correction factors, see also  ä 59 ff, section "Diaphragm seal filling oils".

• The temperature coefficient "T

Ambient" is listed in relation to the capillary length on  ä 60 in the

"Influence of the temperature on the zero point" section.

• The weights of the diaphragm seals are given in the tables. See  ä 33 for the weight of the transmitter and  ä 51 for the weight of the housing.

• The following drawings are drawings that illustrate how the system works in principle. In other words, the dimensions of a diaphragm seal supplied can deviate from the dimensions given in this document.

Operating elements On-site display (optional)

A 4-line liquid crystal display (LCD) is used for display and operation. The on-site display shows measured values, dialog text as well as fault and notice messages in plain text, thereby supporting the user in every stage of operation. The liquid crystal display of the device can be turned in 90° steps. Depending on the installation position of the device, this makes it easy to operate the device and read the measured value.

Functions:

• 8-digit measured value display including sign and decimal point, bar graph for 4 to 20 mA HART as current display or for PROFIBUS PA as graphical display of the scaled value of the AI Block

• Simple and complete menu guidance thanks to seperation of the parameters into three levels

• Ech parameter is given as 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.)

• Rapid and safe commissioning with the Quick Setup menus

Planning instructions, diaphragm seal systems

With the Endress Hauser selection tool "Applicator" you will find the optimum diaphragm seal for your application. Online on "www.endress.com/applicator" or offline (on CD) For further information please contact your local Endress+Hauser Sales Center.

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 ( ä 28, section "Process temperature limits".)

• In the case of process media that crystallise

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

• In the case of heterogeneous and fibrous process media

• If good and rapid measuring point cleaning is necessary

• If the measuring point is exposed to vibrations

• For mounting locations that are difficult to access

Design and operation mode Diaphragm seals are separating equipment between the measuring system and the process medium.

A diaphragm seal system consists of:

• A diaphragm seal in a one-sided system, e.g. FMD77 or two diaphragm seals, in a two-sided system, e.g. FMD78

• One capillary tube or two capillary tubes

• Fill fluid and

• A differential pressure transmitter.

The process pressure acts via the process isolating diaphragm of the diaphragm seal 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 your local Endress+Hauser Sales Center.

Diaphragm seal

The diaphragm seal determines the application range of the system by

• the process isolating diaphragm diameter

• the process isolating diaphragm stiffness and material

• the design (oil volume).

Diaphragm diameter

The larger the diaphragm diameter (less stiffness), the smaller the temperature effect on the measurement result. Note: To keep the temperature effect in practice-oriented limits, you should select diaphragm seals with a nominal diameter of DN 80, in as far as the process connection allows for it.

Diaphragm stiffness

The stiffness is dependent on the process isolating diaphragm diameter, the material, any available coating and on the diaphragm thickness and shape. The diaphragm thickness and the shape are defined constructively. The stiffness of a process isolating diaphragm of the diaphragm seal 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:

• DN 50: 1 mm

• > DN 50: 2 mm

The capillary tube influences the T of a diaphragm seal system as a result of its length and internal diameter.  ä 60 ff, sections "Influence of the temperature on the zero point", "Ambient temperature range" and "Response time".

Diaphragm seal filling oils

Observe the installation instructions regarding capillary tubes. See  ä 64 ff, section "Installation instructions".

Filling oil

When selecting the filling oil, fluid and ambient temperature as well as the operating pressure are of crucial importance. Observe 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 harmless to health 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 T

zero point and the temperature operating range of a diaphragm seal system

and the response time.  ä 60 ff, sections "Influence of the temperature on the zero point" and "Response time".

Differential pressure transmitter

The differential pressure transmitter influences the temperature operating range, the T

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 optimised with regard to minimum volume change and side flange.

Influence of the temperature on the zero point

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 (constant in the range: +21 to +33°C (+69.8 to 91.4°F)).  ä 59, section "Diaphragm seal filling oils". For example, the filling oil expands in the event of a temperature increase. The additional volume presses against the process isolating diaphragm of the diaphragm seal. 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 "T

Process", see  ä 43 ff, section "Process connections FMD78".

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 process isolating diaphragm material AISI 316L/1.4435. For other filling oils, these temperature coefficients must be multiplied by the T

correction factor of the corresponding filling oil. For the TK correction factors, see  ä 59, section

"Diaphragm seal filling oils".

Ambient temperature range The operating temperature range of a diaphragm seal system depends on Fill fluid, "Capillary length and

internal diameter, Process temperature and Diaphragm seal oil volume. The range of application can be extended by using a fill fluid with a smaller expansion coefficient and a shorter capillary. The permitted operating temperature ranges in relation to the capillary length can be calculated online at "Applicator Sizing Diaphragm Seal": http://www.endress.com/applicator -> Applicator Sizing Diaphragm Seal -> Horncurve

P01-xxxxxxxx-20-xx-xx-en-001

Note!

• Endress+Hauser recommends you use a low temperature oil for applications that require short response times or are close to the lower temperature limit (see "diaphragm seal fill fluid").

• Please contact your Endress+Hauser sales office for further information, comprehensive diaphragm seal system designs and measuring technology solutions that are close to the application limits.

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 response time of the transmitter must also be taken into consideration.

• 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.

• In the case of devices with diaphragm seals and capillaries, the zero point shift caused by the hydrostatic pressure of the filling liquid column in the capillaries must be taken into account when selecting the measuring cell. If a measuring cell with a small measuring range is selected, the sensor nominal range can be overdriven as a result of position adjustment.  See the following diagram and the following example.

• For devices with capillary a suitable fastening device (mounting bracket) is recommended.

• When using a mounting bracket, sufficient strain relief must be allowed for in order to prevent the capillary bending down (bending radius 100 mm).

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

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.

Installation instructions

In order to obtain more precise measurement results and to avoid a defect in the device, mount the capillaries as follows:

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

• not in the vicinity of heating or cooling lines

• insulate if the ambient temperature is below ore above the reference temperature

• with a bending radius of 100 mm.

Vacuum applications

For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter underneath 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 smallest ever pressure that is permitted to occur at the diaphragm seal on the positive side (empty tank), see the following illustration, on the right.
