ABSTRACT

Water Level Indicator using 7segment display

In current scenario mostly High rise buildings Housing complexes and societies have a requirement for storage and pumping of water. Where raw water is drawn from ground, after that it goes through softener and at last boosting to overhead tanks. It requires WATER AUTOMATION for Hotels, Restaurants, Dairies, Municipal corporations and Industrial users, in current scenario mostly High rise buildings Housing complexes and societies have a requirement is important for consultants and architects to design water supply and disposal in such a way as to ensure that the users never have to worry about handling pumps and checking levels as a routine.

The water level switches work to maintain a constant water level avoiding material wastage in your process plant. Common applications also include switching pumps on and off to avoid overflow, dry running and indicating water level in an empty tank to avoid wear and tear and production stoppage..

This is the circuit of a simple corrosion free water level indicator for home and industries. In fact the level of any conductive non corrosive liquids can be measured using this circuit. The circuit is based on gate switches. Each gate is switched on to drive the corresponding seven segment display, when its terminal is supplied with current through the water through the electrode probes.

This water-level indicator uses a 7-segment display, to indicate the water level (low, half and full) in the tank. Moreover, a buzzer is used to alert you of water overflowing from the tank.
