A water level indicator is an automated system used to detect and indicate the level of water in a tank. It helps to avoid overflow of water from the overhead tanks. It saves a lot of water, power and time. Saveon water level indicators in Chennai are designed along with 8051 microcontrollers. The controller is designed in a way to do the corrective action needed, based on the indication of the water level indicator. If the alarm on the water level indicator is low, the controller operates the valves to fill the tank. If the indication is high, the controller switches off the motor, closes the valves and stops the water flow to the tank. The 8051 microcontrollers automatically switch on the motor and opens the valves to fill a tank if it is empty and switches off the motor and turns off the valves if the tank is full. The above process is based on the indication of the water level of the tank as displayed on the water level indicator. There are three levels- high, medium and low.
