Abstract
A fluid level determining system is for determining a fluid level of a fluid in a reservoir having an interior surface and an opposite, exterior surface. The fluid level determining system includes an emitter configured to be positioned along the exterior surface of the reservoir and emit signals into the reservoir and a receiver configured to be positioned along the exterior surface of the reservoir such that the receiver is oriented in the direction of the emitter. The receiver is configured to receive signals from the emitter passing out of the reservoir. The signals received by the receiver are attenuated relative to the signals emitted by the emitter into the reservoir. A controller is in communication with the receiver and configured to determine the fluid level based on the signals received by the receiver.
