Internal structure of the individual Transducer Blocks
The "Flow" Transducer Block receives a signal variable (Volume) from the sensor as the input signal.
The amplifier converts this input signal to volume flow. The amplifier calculates the current mass
flow via the "Density Param. - Fixed Value" parameter (
Page 87) by deriving the value from
the measured volume flow.
Optionally, the empty pipe detection function can be adjusted and switched on or off by means of
the EPD parameter group.
