Abstract:
1. A fluid level sensor system comprising: a thermal path component at least partially disposed within a fluid containing volume, the thermal path component including a heat source operably coupled thereto and a control temperature sensor for sensing a control temperature of the thermal path component, wherein the thermal path component is aligned in a relatively vertical manner within the fluid containing volume, the thermal path component comprises a first end and a second end, and wherein the control temperature sensor is disposed proximate the first end and the heat source is disposed proximate the second end; a reference temperature sensor for sensing a reference ambient temperature; and a controller in operable communication with the control temperature sensor, the heat source and the reference temperature sensor, wherein the controller maintains a predetermined temperature difference between the control temperature and the reference ambient temperature by controlling the heat source, wherein an energy level required to maintain the predetermined temperature difference is converted to a fluid level within the fluid containing volume.
