The probe is mounted from the top of the vessel and it comprises of a sense electrode which is electrically isolated from the metallic tank by means of a suitable insulator. The sense electrode and the vessel wall serve as the two electrodes of a capacitor with the service material acting as the dielectric. A change in the material level causes a change in the dielectric, which in turn causes the value of this tank capacitor to change. An accurate measurement of this change affords an indirect measure of the level of the material in the tank.
