A system and method for turning on and off a bilge pump whereby bilge water level is detected using level sensors and bilge pumps are turned on and off based on the detected water level. The system further incorporates an automatic transmission outside the watercraft to alert of the water level in the bilge. The system is controllable from within the watercraft and remotely controllable through wireless transmission.

A sensor system for sensing liquid level in a bilge, for use in automatic bilge pump actuation. First and second field effect sensors are potted or sealed within a container or the bilge wall and are aligned in a vertical array and each comprise a substantially planar pattern of “electrodes” or conductive traces disposed on a printed circuit board (PCB) along with integrated circuits used to create a loop or arc-shaped electric field. As bilge liquid rises to the proximity or level of the field effect sensors, a change in the arc-shaped electric field is sensed and, in response, a bilge pump is automatically actuated to pump liquid out of the bilge. Optionally, the pump control can be programmed by use of a microprocessor to permit control of on-off timing and prevent undesirable effects of “sloshing.”

An improved bilge water level monitor, alert and control system for boats and other vessels. The system provides a method of detecting excessive leakage of water into the bilge and in response to the excessive water in the bilge, triggering an alarm to notify the operator and others and energizes bilge pumps to remove the excessive water. The system is designed with many redundancies in the sub elements and subsystems for safety. The system provides a means for reducing the likelihood of exhausting battery power in the event of a significant seawater leakage problem. The electrical power rating of the monitoring circuitry components is relatively low, thereby reducing the size and weight of those components relative to prior bilge pump monitoring and alert systems. There is no electrical wiring exposed to bilge water during system operation thereby reducing damage to the wiring components. The water level detection and control circuitry operates with sufficiently low amperage to substantially eliminate the hazard of spark-induced combustion.
