Method and Apparatus for Water Level Sensing

A water sensing apparatus for a reservoir, the apparatus including:

• a liquid conveyor tube that pivots between a raised configuration and a lowered configuration;
• a level sensing device is installed along the length of the liquid conveyor tube;
• a processor module is coupled to the level sensing device for receiving a signal indicative of a water level in the reservoir;
• wherein, with liquid conveyor tube in the lowered configuration, the level sensing device provides a signal indicative of a water level in the reservoir.

A method of sensing water level in reservoir for calculating water flow there from, using an apparatus according to claim 1, the method comprising the steps of:

• receiving a plurality of water level signals each indicative of respective water level state at a predetermined location within the reservoir;
• identifying change of a first water level state;
• recording a relative first time, with respect to water flow duration, at which the first water level state changed;
• identifying change of a second water level state;
• recording a relative second time, with respect to water flow duration at which the second water level state changed;
• calculating average water flow rate from the reservoir using a known volume held by the reservoir between the change of the first water level state and the change of the second water level state and the water flow duration between the first time and the second time;
• and
• associating the average water flow rate with a water level location within the reservoir.
