To offer the possibility of working at constant test pressure RG eConcept introduces pressure regulation.

​

• This is a PID regulator in the SmartFlow software that controls a motorized valve through the FCU, a valve that controls a discharge from the air source and allows the test pressure to be adjusted continuously.

• The advantage of such an economical solution is the easy adaptation to all models of air source without affecting the power supply of the source motors. It suffices to mount the valve on a T inserted in the air circuit of the flowmeter.

• The complete option consists of the motorized valve, a cable connecting it to the FCU and its 12 V power supply which also connects to the FCU.

• It is possible by software to choose the regulation or not.

• The test pressure set point range is 5 to 30 "H2O. In a few seconds the pressure is regulated with a static error (deviation from the set point) of +/- 3%
