Item Term/abbreviation Explanation

1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device depends on the lowest-rated element,

with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional notes see the →  32 section. The OPL may only be applied for a limited period of time.

2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-rated element, with regard to

pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. For the relevant standards and additional notes see the →  32 section. The MWP may be applied at the device for an unlimited period. The MWP can also be found on the nameplate.

Measuring principle Metallic process isolating diaphragm

1 Sensing element 2 Overload diaphragm/Middle diaphragm 3 Filling oil 4 Process isolating diaphragm

The metal separating diaphragms (4) are deflected on both sides by the acting pressures p1 and p2. A filling oil (3) transfers the pressure to a resistance circuit bridge (semiconductor technology). The differential- pressure-dependent change of the bridge output voltage is measured and further processed.

Your benefits

• Choice between five flow modes of operation:

• Volume flow

• Norm volume flow (European norm conditions)

• Standard volume flow (American standard conditions)

• Mass flow

• %

• Choice of diverse flow units with automatic unit conversion.

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

FOUNDATION Fieldbus

The digital communication signal is transmitted over the bus via a 2-wire connection. The bus also provides the power supply. For further information on the network structure and grounding and for further bus system components such as bus cables, see the relevant documentation, e.g. Operating Instructions BA00013S "FOUNDATION Fieldbus Overview" and the FOUNDATION Fieldbus Guideline.

• Supply voltage and internal ground terminal: 0.5 to 2.5 mm2 (20 to 14 AWG)

• External ground terminal: 0.5 to 4 mm2 (20 to 12 AWG)
