Abstract

The liquid level is measured by different techniques of which capacitance techniques has wide application in measurement of level of aqueous solution in a storage tank by using insulated metallic rod electrode immersed in a metallic tank or two such identical electrode immersed in a non metallic tank. This measurement may suffer from inductance effect. Hence, the system likes a coaxial cable which has both inductance and capacitance effect. In the present paper an improved capacitance probe is designed which has no inductance effect. The theory of operation of this sensor has been explained in the paper. The sensor has been designed and tested experimentally. The experimental results are described in the paper. A very good linearity has been observed.
