Pressure Drop Curves - Siemens SITRANS F Series Operating Instructions Manual

11.8.2

Pressure drop curves

The pressure drop is dimension-dependent and influenced by process media viscosity and
density. Sensors with undersized process connections experience higher pressure drop due
to reduction in inlet/outlet dimensions.
Note
Pressure drop information
Pressure drop information is available on request.
