US Patent 11906990 Water level detection via pressure sensing device

A water level detection system includes a water containing vessel, an airtight tube fluidly coupled to the water containing vessel, a pressure sensor fluidly coupled to the airtight tube, and a water level control unit communicably coupled to the pressure sensor. The water level control unit is configured to control at least one of a height of water within the water containing vessel or a temperature of the water based on pressure data from the pressure sensor.
