5.5. ACCESSORIES
5.5.1. Diaphragm leakage detector
The diaphragm leakage detector is an electrical conductivity sensor capable of detecting the presence of
liquid when its conductivity is 0.05 mS or higher. The pump must be provided with the specific diaphragm
flange for housing the detector.
Fit the detector Ref. 29-056 in the lower orifice of the diaphragm and
connect pins 8-9 as shown in the drawing.

5.5.2. Flow detector
The flow detector is a device which monitors the delivered pulsated flow. The pulses are received and
processed by the Advance Control Unit in order to detect dosing failures like lack of priming, cavitation
or check valves faults. The unit compares the strokes of the pump with the pulses from the detector and
allows an alarm to be set according to the configuration parameters.
5.5.3. Pressure sensor
The pressure sensor protects the pump from working in overpressure conditions, when the pressure
alarm is activated. Connect the 4 - 20 mA 10 bar pressure sensor Ref. 18705 as shown in the drawing.
