PROJECT DESCRIPTION

The project is designed to give a display of water level in a tank. The reading given is in the sale of 0 to 9. A priority encoder is interfaced to a decoder to get the display of water level on 7 segment display.

This is the circuit designed for overhead tank digital water level indicator. It is built around priority encoder, BCD-to-7-segment decoder, 7-segment display and a few discrete components. Due to high input impedance, priority encoder senses water in the container from its nine input terminals.

The inputs are connected to +5V. The ground terminal of the sensor must be kept at the bottom of the container (tank). Priority encoder has nine active-low inputs and converts the active input into active- low BCD output. It uses a 7-segment display to show the water level in numeric form from ‘0’ to ‘9.’

The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of different ICs and components.

Further the project can be enhanced by interfacing it with a buzzer to alert when the water level is falls below the minimum level.

Q & A
Q:  What is water level indication?
A:  It indicates the level of water in the tank
Q:  Can this also be used for other purpose?
A:  Yes, it can be used for any partially conducting non corrosive and non inflammable liquid.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
