Design and Implementation of a Water Level Controller
An automatic regulator suitable for water level sensing and control was realized using the MC14066 integrated circuit. This enabled the entire circuit to function as a threshold detector; thus working as an ON/OFF switch. The proposed water level sensor was tested in real time application by using it to control the level of water in a tank fed by a single phase 0.5 HP AC pump. Experimental performance results indicated that the device is quite suitable for the desired operation, since it maintained the set maximum and minimum levels of 50 litres and 10 litres respectively, by switching the pump on or o as required.
