Abstract
A system for automatically controlling a pumping unit used in fire suppression comprises a pumping unit, a water flow sensor and a pump controller. The pumping unit has a pump with a suction inlet configured to receive water from an upstream pumping unit and an engine to run the pump. The water flow sensor senses water flow into the suction inlet of the pumping unit. The pump controller receives a water flow sensor signal from the water flow sensor and controls an on/off state of the engine based on the water flow sensor signal.
