Liquid level sensing system

1. A liquid level sensing system comprising:

a float system including a float member having a float cap including a first end and a second end, and a float body coupled to the second end of the float cap;

a tether having a first tether end and a second tether end, the first tether end coupled to the float member, at the first end of the float cap, and the second tether end fixedly secured to a fixed member;

an accelerometer configured to provide an output signal representative of a position of the float system, where the accelerometer is positioned within the float cap and where the accelerometer is a three axis accelerometer that provides the output signal representative of an angle of the float system relative to the direction of gravity; and

a float control system that determines a liquid level using the output signal and a tether length.

a discharge system, where the tether is coupled to the discharge system; and

wires routed between the float control system and a system controller via the tether, where the tether is a conduit for the wires,

where the system controller receives the output signal and operates a pump based on the output signal.

11. The liquid level sensing system of claim 9 , comprising:

a pump coupled to the discharge system, where the float control system provides a first liquid level output signal based on a first float position and a second liquid level output signal based on a second position, and where system controller activates the pump when the output signal reaches the second liquid level output signal.

12. The liquid level sensing system of claim 11 , where the system controller continues to activate the pump until the output signal returns to the first liquid level output signal.
