The medium velocity is measured in the measuring component (sensor electronics) and converted into a flow rate signal. The positioning signal Y corresponds to the power requirement Q at the exchanger. The volumetric flow is regulated in the EPIV. The positioning signal Y is converted into an equal-percentage characteristic curve and provided with the max value as the new reference variable w. The momentary control deviation forms the positioning signal Y1 for the actuator. The specially configured control parameters in conjunction with the precise flow rate sensor ensures a stable control quality. They are however not suitable for rapid control processes, i.e. for domestic water control. The measured flow rate is in l/min as an absolute volumetric flow output. The absolute position sets the valve opening angle in %. The relative position always refers to the nominal flow nom, i.e. if max is configured with 50% of nom, then the relative position at a setpoint of 100% is equal to 50% of nom.RelPos [%]1
