Your benefits
• Choice of four flow modes of operation: volume flow, corrected volume flow (European norm conditions),
standard volume flow (American standard conditions) and mass flow.
• Choice of diverse flow units with automatic unit conversion.
• A customized 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 Deltatop product family, Endress+Hauser is offering universal and reliable solutions for flow
measurement:
– Deltatop, the compact, ready-to-use flow measuring unit including the Deltabar S differential pressure
transmitter
