The water level indicator circuit is defined as a system that gets information about the water level in tanks. By using the water level indicator with alarm circuit diagram we can overcome the overflow of water from the tankers.

A water level indicator alarm circuit is a system that relays information back to a control panel to indicate whether a body of water has a high or low water level. 

Some water level indicators use a combination of probe sensors or float switches to sense water levels. “The Water Level Indicator for water tank circuit employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container.” 

The purpose of a water level indicator circuit is to gauge and manage water levels in a water tank. The control panel can also be programmed to automatically turn on a water pump once levels get too low and refill the water back to the adequate level.

The working principle of a water level indicator for water tank is actually quite simple. Water level indicators work by using sensor probes to indicate water levels in a storage tank. These probes send information back to the control panel to trigger an alarm or indicator. 

As mentioned above, the control panel can be programmed to automatically turn on your pump to refill the water again.

Water Level Indicator Alarm Circuit Explanation

The principle of this water level indicator for water tank circuit is very easy to understand and it is very practical. I used IC ULN-2003 in this circuit. 

If the water level rises in the tank, then the water comes into contact with probes which are from IC Pin 1 to 7 and thus the pin 7 through 1 high sequentially. 

Hence the equivalent output pins 10 to 16 will go low one after another and the LEDs from 1 to 7 will go in the order. If the water level is at the final probe Pin 7 then the sound is produced by the piezo-buzzer.
