By means of a relay employed to drive a water pump this circuit provides automatic level control of a water reservoir or well.
Water level control circuit using relays.
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.
This is a circuit for water level controller is based on transistors and relays.
This is the circuit to determine the level of water in the process tank using relay based on off control.
How the operation of relay based on off control system is.

Anyway the given concept includes automatic water level control and high low voltage cut off.
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.
Liquid level control relays detect control levels of conductive liquids such as fresh water seawater sewage coffee see table below for other liquids.
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.
Please find the attached circuit for a very simple and cheap water level controller.
Water reservoir automatic level control simple circuitry 12v supply.
This simple water level controller circuit is useful to control the water level in a tank.
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 shorter steel rod is the water high sensor whereas the longer is the water low sensor.
It does this by turning on and off a water pump depending on the status of the sensors.
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.
Water level controller circuit.
Thaks momename right now i am using two level switches and one relay to control the pump to fill up a tank.
