LEAK DETECTION (DIAPHRAGM FAILURE DETECTOR)
GENERAL DESCRIPTION
An ARO® diaphragm pump equipped with the ARO Diaphragm Failure Detector warns of a diaphragm failure by sensing the presence of liquid in the air chamber of the pump. This system uses a liquid sensor in each of the two air cham- bers which will send an output signal when fluid is detected.
