Measuring ranges depending on the inner diameter of the pipe
The sensor VA 400 - standard version with or without display,
has a maximum
measuring range of
92.7 m/sec
. The flow rate is programmed to: Inner diameter:
53.1 mm
This corresponds with an analogue output 4… 20 mA of
0…600 m³/h
0…10 m³/min
0…10000 l/min 0…166.6 l/sec 0…92.7 m/sec.
In case of the version with display the inner diameter 25.00 has to be set first if the sensor is
used in other pipes, e. g. 1", 25 mm.
The analogue output for 1" can be taken from the table below: 4… 20 mA =
0…122.2 m³/h
0...2.04 m³/min 0…2036.6 l/min 0…33.94 l/sec
0…92.7 m/sec.
In case of the version with display please adjust the respective inner diameter (see page 21).
