Water Level Control Circuit Using Relays

It does this by turning on and off a water pump depending on the status of the sensors.

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. Thaks momename right now i am using two level switches and one relay to control the pump to fill up a tank. Water reservoir automatic level control simple circuitry 12v supply. Liquid level control relays detect control levels of conductive liquids such as fresh water seawater sewage coffee see table below for other liquids.

How the operation of relay based on off control system is. 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. They provide a low voltage signal typically 5vdc pulsed to prevent electroplating issues to a probe or probes and a common connection on the tank. 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 the circuit to determine the level of water in the process tank using relay based on off control. My question was in case a level switch got a problem i could change the control building the circuit of your design. 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. This simple water level controller circuit is useful to control the water level in a tank.

This is a circuit for water level controller is based on transistors and relays. 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. Please find the attached circuit for a very simple and cheap water level controller. Water level controller circuit.

With a nc normally closed or a no normally open contacts of the relay rl we can handle any type of starter. The shorter steel rod is the water high sensor whereas the longer is the water low sensor.
