Automatic water level controller circuit.
Float switch water level controller circuit.
The proposed water level controller circuit using a float switch is basically a semi automatic system where the pump is started manually by press of a button once the water level reaches the brim of the tank the operation is switched of automatically by means of a float switch.
Why a float switch.
Let s start with the most basic float switch.
A two wire single pole single throw float switch the rising action of the float can either close i e turn on a normally open circuit or it can open turn off a normally closed circuit installation scenarios might include a normally open float switch turning on a pump to empty a tank control schematic 2 or a normally closed.
The advantage of a float switch is that it works without a direct contact with the water making the procedure free from all sorts corrosion or mechanical degradation problems.
The water level is sensed by two floats to operate the switches for controlling the pump motor.
For example water level controls is a float switch manufacturer that is revolutionizing the way float switches are used for water level sensing.
This system utilizes two levels of float switches a 12v relay and a 120v relay to drive the pump.
I have discussed a host of different water level controller circuits in this blog however all have incorporated a direct contact with water for sensing the levels and for activating the connected.
Also all of the electronics are built into the head so you can.
Water level control s float switches work by using probes instead of float switches.
This sends current to the common com pin of the 12v relay.
Such sensors are more reliable than.
Water level control s new float switches work by using probes instead of floats to detect or sense.
This relay s coil is also rated at 120vac so our water level control can switch it on off at rated voltage.

12v dc is supplied to the float switches which are normally open when not being floated.
As the water level rises it lifts the bottom float float 1 and closes it.
How new float switches work.
The sensor probes actually act as their own sensors and do not pass electricity through the probes which keeps them from fouling degrading and deteriorating.
This arrangement is encased in a pvc pipe and fixed vertically on the inside wall of the water tank.
The second schematic shows how a pump up to 2hp can be wired for proper operation.
Float switches of the 21st century have come much further in the amount of operations your float switch can perform.
