Water Level Control Circuit Using Relays

With your new circuit i can clearly see where to incorporate the two transistors to control the relay for switching power to pump and heater.

Water level control circuit using relays.

The circuit automatically switches on the pump when water is low in the tank and switches the pump off when water reaches a predetermined mark. The scr in my case is not needed so i can use n1 gate to turn on an extra led placed at the correct place for a more accurate water level indicator and include a buzzer for audio warning when water. This is the circuit to determine the level of water in the process tank using relay based on off control. It does this by turning on and off a water pump depending on the status of the sensors.

This design is only a basic portion of my own marketed product having unsafe voltage cutoff dry run cut off and led alarm indications and overall protection. My question was in case a level switch got a problem i could change the control building the circuit of your design. Please find the attached circuit for a very simple and cheap water level controller. How the operation of relay based on off control system is.

With a nc normally closed or a no normally open contacts of the relay rl we can handle any type of starter. To explain how it operates the images below will show a ladder diagram left side figure and a pictorial diagram right side figure for a visual concept of what happens with. By means of a relay employed to drive a water pump this circuit provides automatic level control of a water reservoir or well. This is a circuit for water level controller is based on transistors and relays.

This simple water level controller circuit is useful to control the water level in a tank. Joydeep kumar chakraborty. Anyway the given concept includes automatic water level control and high low voltage cut off. The shorter steel rod is the water high sensor whereas the longer is the water low sensor.

Liquid level control relays detect control levels of conductive liquids such as fresh water seawater sewage coffee see table below for other liquids. Thaks momename right now i am using two level switches and one relay to control the pump to fill up a tank.
