PLC Based Water Level Control System

A PLC is a digital computer used for automation of electromechanical processes and industry purpose. This is a very most important for automation purpose.so that this type project safe a water and any type of boiler automation system at which some time. I have used Siemens plc for water level control system. In this type plc is a very simple programming language so that this project used a four float switch sensor. Two float switch sensor is used a upper tank and two float switch sensor is used bottom tank. It is on this platform that the need to minimize or check water wastage arouse. Water is a free gift of nature but due to its indispensability to human existence; it should be conserved for the purpose of constant availability or sufficiency. Moreover, in order to take a good care of this problem of wastage, there is need for the construction of water level controller this will guide against unnecessary wastage of water, for it will make a reasonable quantity of water to be used a any time. In this project, effort has been made to construct a water controller that is capable of controlling the electric water pumping motor operation in regard switching on or off at predetermined level of water in the storage tanks or reservoirs. This project also gives the clarity of advantage of using an automatic method of controlling level over human or manual control method.
