China Anhui Tiankang TKWL-1700 Capacitance level gauge is composed of capacitive material level sensor and circuit checking capacitance, whose basic working principle is the change of converting material level into capacitance with capacitive material level sensor, and then calculate the value of material level with the method of measuring capacitance. Capacitance level meter works based on the principle of cylinder capacitor, whose structure is similarto two cylindrical metal conductors with length of L, radiuses of R and r respectively; the middle is separated with insulating material and when the filled medium in the middle is the gas with dielectric constant of e1, the capacitance of two cylinders is: If the measured medium is conductive liquid, the electrode needs to be covered with insulator (such as polyethylene) as intermediate medium, while the liquid and external cylinder are as outer electrodes. Presume the dielectric constant of intermediate medium is e3 and the immersed length of electrode is 1, and then the capacitance of capacitor is: In which R and r are outer radius of insulating coating and outer radius of inner electrode. As the e3 is constant, so C and I are in direct ratio. If part of electrode is immersed by liquid (non-conductive) with dielectric constant atc2, and then there must be increase of capacitance AC produced (becauseE2>e1) , now the capacitance between these two electrodes is C=C1+AC. Presume the immersion length of electrode is I, and then the increase of capacitance is: When e2, e1, R, r keep unchanged, the increase of capacitance AC and immersed length of electrode I are in direct ratio, therefore, the liquid level can be gotten after the value of capacitance increase is measured.
