'design and development of cut-off relay for overhead tank'

摘要

Cürrently there is a major problem in water scarcity, its wastagé frórh the over heád tanks due to over ñow and consumption of unñecessary power from continuous running. The water touches a certain level at circuit block, the motor will stop running autómatically, and prevenís from over flow of water. While switching on the motor again, the water insidé the circuit block should be drained out and power supply to the motor comes its position back. The water level indicator is also incorporated along with this system as a sepárate paft. This. work is designed, implemented and simulated in one flat at Ambattur, Chennai. This.type of system can be utilized in various places such as any organization, educational institute, domestic and rural applications. The main aim of this work is to minimize the cost of build and making it work efficiently as compared to another systems.
