Installation
direction Select the installation
direction. • Flow in arrow direction (forwards)
Positive flow measurement in the direction of the arrow.
• Flow against arrow direction (backwards)
Positive flow measurement in the opposite direction of the arrow.
Flow in arrow direction

On value Enter the on value for
low flow cut off. Positive floating point number

A flow measured value that is less than the value of the on value
forces the display to zero. In the event of plant downtime, this
prevents the totalizer from continuing to totalize even though
there is no flow.
The measured value flashes on the display when low flow cut off is
active.
Low flow cut off is deactivated again as soon as the flow measured
value exceeds 1.5 times the on value.
Depends on the nominal
