The diaphragm leakage detector is a conductivity sensor which is able to detect
conductive liquids, with a minimum conductivity of 0.05mS. The pump must be
provided with the specific diaphragm flange to hold the leakage detector.
The flow detector is a device, which monitors the pulsated delivered flow. The
pulses are received and processed by the Advance Control Unit in order to
detect dosing failures like not priming, cavitation or check valves problems. The
unit compares the strokes of the pump with the pulses from the detector.
When the pump does 40 strokes with no signal from the flow detector and alarm
The pessure sensor protects the pump against overpressure when the pressure
alarm is activated. Connect the pressure sensor 4-20mA 10Bar Ref. 18705 as
shown in the drawing.
