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

Flow measurement with Deltabar S and primary element, left: Orifice plate and right: Pitot tube

Q Flowp 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

annual quantity totalizing.

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.
