Abstract
A liquid level sensor frequency output system for efficiently communicating a liquid level with reduced power and increased accuracy. The liquid level sensor frequency output system generally includes a sensor that determines a liquid level, a transmitter in communication with the sensor that converts the level data to a signal having a frequency representing the liquid level, and a receiver that receives the signal, wherein the receiver calculates the liquid level based on the frequency of the signal. The calculated liquid level by the receiver can be transmitted to an output device such as a display, switch, warning system or pump.
