Water Level Control Circuit Using Relays

The shorter steel rod is the water high sensor whereas the longer is the water low sensor.
Water level control circuit using relays. Please find the attached circuit for a very simple and cheap water level controller. 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. Liquid level control relays detect control levels of conductive liquids such as fresh water seawater sewage coffee see table below for other liquids. Joydeep kumar chakraborty.
Thaks momename right now i am using two level switches and one relay to control the pump to fill up a tank. How the operation of relay based on off control system is. By means of a relay employed to drive a water pump this circuit provides automatic level control of a water reservoir or well. With a nc normally closed or a no normally open contacts of the relay rl we can handle any type of starter.
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. This is the circuit to determine the level of water in the process tank using relay based on off control. 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. Water level controller circuit.
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. Anyway the given concept includes automatic water level control and high low voltage cut off. 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.
It does this by turning on and off a water pump depending on the status of the sensors. Water reservoir automatic level control simple circuitry 12v supply.
