A sensor to find liquid level in a tank is a cylindrical capacitor of length with outer and conductor radii R_(0)and R_(i) respectively. When a liquid fills the tank up to height h, (h le l)tank.s bottom the dielectric in lower part is liquid (K_l)and dielectric in upper part is vapour liquid (K_r)When liquid fills the tank up to height h, the capacity of capacitor is |
