The ALM-9 Pump Monitor generates an alarm signal if flow failure is encountered. This alarm signal is carried to the ALM-9 from the pump over the standard pump cable and initiates a piezo-electric buzzer, large flashing red LED and energizes a DPDT relay. Typical applications include automatic switching on of a backup pump and triggering a SCADA input. Download the ALM-9 Data Sheet.
