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.
