Capacitance level transmitter/sensor/gauge is a measuring instrument that uses the change of capacitance to measure the medium level in the container. Inside the container, the container wall made of electrodes and conductive material forms a capacitor. For a given electrode, when the dielectric constant of the measured medium is constant, a fixed frequency measurement voltage is applied to the electrode, then the current flowing through the capacitor depends on the height of the medium between the capacitor electrodes and is proportional to it.
