Summary:

Accurate remote sensing or control of liquid levels is of interest in a variety of applications. A method capable of distinguishing between the presence and absence of liquid at a discrete level by monitoring the rate of heat transfer from a solid-state sensing element is discussed; a detailed description is given of the silicon sensor and the associated electronic circuitry. Small size (0.50 0.50 0.15mm3) and low thermal conductance mounting of the active element assure precise level determination and rapid response, while an auto-referencing scheme used in the circuit permits reliable operation over a wide temperature range. Three versions of the system are described, each suited for different types of level sensing applications. Suggested among the possible uses are a number of automotive applications such as crankcase, transmission, and brake fluid measurements
