An accurate measurement of change in admittance affords an indirect measure of the level of material in the tank. The electronic insert measures this change accurately by using Radio Frequency (R.F.) technique coupled with coat immunizing circuitry. The change is converted to a DC voltage variation, which is transmitted to the evaluation unit via a 3-core cable for further processing. The processed signal is used to energize or de-energize a relay whose output contacts are available for annunciation and/or control.
