发明名称 Self-Calibrating Capacitive Liquid Level Sensor Assembly and Method
摘要 A method of determining level of a liquid between empty and full conditions within a container includes: providing first and second elongate capacitors, each capacitor being independently capable of measuring the liquid level at least between the empty and full conditions within the container, with the second capacitor being longer than the first capacitor; determining first and second capacitance values for the first and second capacitors, respectively, based on the liquid level height; and dividing the first capacitance value by a difference between the second and first capacitance values to thereby obtain a liquid level value independent of the dielectric constant.
