characteristics. All the values indicated in the figures below
apply irrespective of the direction of flow, whether A->B or B->A.
The flow rate range permitted for a measurement must be between 30 ml and a maximum of 300 ml.
In the event you are unable to achieve these flow values, there are various conditioning modules
available from our extensive line of accessories.

Example:
You are using a fluid with a viscosity
p
Δ
of 46 mm²/s at a differential pressure
p
Δ
of 1 bar, so that
you achieve a flow rate of approx. 100 ml/min.
The flow rate corresponds to the viscosity of the medium and the differential
p
Δ
pressure .
