The differential pressure between P
mbar depending on the model. This differential pressure is calculated for the proper
operation of the flow rate regulator.

The flow curves show the relationship between

The different flow rates are adjusted by means of the regulating valve of the flowmeter. The
counter pressure P2, in these cases, corresponds to the atmospheric
