Abstract

An Electric Water Pump Controller and Level Indicator (EWPCLI) has been designed, constructed and tested.The EWPCLI exploits the electrical conductivity of water to give indication of water level in a storage tank and ultimately, the automatic control of the water pump. The EWPCLI employs a number of metallic conductors or probes, each positioned at separate levels along the tank height to act as sensors. Comparators monitor the presence of water at the probes (utilizing the conductivity of ionized water due to its impurities) and give out corresponding digital outputs which are used by the microcontroller to drive digital outputs which turn on visual display LEDs that indicate various water levels in the tank. The microcontroller also controls a switch to turn the water pump on (when water goes below the preset minimum level) or off (when water goes above the chosen maximum level). EWPCLI when tested turned the water pump on or off depending on the water level in the tank as designed. The required visual LEDs were also turned on at the corresponding water level. The system will help to eliminate the cost and inefficiency of human interference associated with monitoring and controlling the pump while maximizing the performance and life span of the electric water pump.
