Product operation

5.1. Measuring principle

• The sensor measures the flow by means of differential pressure. An orifice in the main channel causes pressure loss at liquid flow

which is measured by the differential pressure sensor. The sensor feedbacks a precise and temperature compensated signal out

of which the electronics calculates the corresponding flow.

• To avoid a blockage of the aperture by contaminated mediums an upstream filter is recommended.
