Abstract
A system that control levels of liquids in reservoirs may include a control component that causes a compressor to pump gas through a tube extending in a liquid in a reservoir to an air bell for a predetermined amount of time responsive to a pump pumping portions of a liquid from the reservoir. The control component may also cause the compressor to pump gas through the tube for a predetermined amount of time responsive to the control component determining that a predetermined amount of time has passed since the compressor was previously operated. The control component may also cause the compressor to pump gas through the tube for a predetermined amount of time, responsive to the control component determining that a pressure sensor component in fluid communication with the tube indicates a possible decrease in the liquid level to at least a predetermined level.
