Commissioning and Measuring Operation
VVX
4.1.1 Flow Measurement
VVX with frequency output:
Depending on the version, the VVX provides
a flow-proportional NPN, PNP or push-pull
square-wave signal.
The frequency changes with the flow ( Fig.).
VVX with analogue, voltage or current output (optional):
The output of the VVX is either the voltage U
or the current I
.
Flow
Flow
The output signal is proportional to the measured flow. The corresponding range is indicated
on the type plate.
4.1.2 Temperature Measurement (Optional)
The temperature is measured by the optional integrated temperature sensor R
, which is
Temp
integrated into the measuring pipe.
Depending on the version, this is an NTC or Pt1000.
For the VVX with analogue output (0.5...3.5 V), the voltage signal U
can also be pro-
Temp
vided. The corresponding range is indicated on the type plate.
