Overhead Water Tank Level Indicator Circuit

The uln2003 can be effectively used for making a full fledged automatic 7 stage water level controller with indicator as shown below.

Overhead water tank level indicator circuit.

Wastage of water is really an issue in places where they use overhead tanks. The water level indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container. Here is a simple automatic water level controller for overhead tanks that switches on off the pump motor when water in the tank goes below above the minimum maximum level. The darlingtons are reasonably rated to handle current up to 500 ma and voltages up to 50 v.

The water level alarm circuit is a simple mechanism to detect and indicate the level of water in the overhead tank and also in the other containers. The water level is sensed by two floats to operate the switches for controlling the pump motor. Each sensors float is suspended. It has numerous transistors acting as a switch and the switch gets activated when the sensors tell them to.

It also prevents dry run of the pump in case the level in the underground tank goes below the. The sensing is done by using a set of nine probes which are placed at nine different levels on the tank walls with probe 9 to probe 1 placed in increasing order of height common probe i e. The above circuit shows a simple water level indicator system based on tranistors and led s. Automatic water level controller circuit.

The water level indicator includes a simple mechanism which helps to detect and indicate the water level in an overhead tank or any other water container the sensing is done by using a set of nine probes which are placed at nine different levels on the tank walls with probe 9 to probe 1 placed in increasing order of height common probe i e. The sensor probes comprise a b c and d where a is the common probe and b c and d are meant for sensing the minimum middle and maximum levels respectively. Uln2003 water level controller circuit. Nowadays all the householders owners are storing the water in overhead tanks by using the pumps.

The simple water level indicator circuit presented here makes this system automatic i e. It switches on the pump when the water level in the overhead tank goes low and switches it off as soon as the water level reaches a pre determined level. Here s a simple water level indicator for overhead tanks that uses three leds led1 led2 and led3 to indicate minimum middle and maximum water levels in the tank.
