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.
Float switch water level controller circuit.
How new float switches work.
12v dc is supplied to the float switches which are normally open when not being floated.
This system utilizes two levels of float switches a 12v relay and a 120v relay to drive the pump.
Water level control s new float switches work by using probes instead of floats to detect or sense.

For example water level controls is a float switch manufacturer that is revolutionizing the way float switches are used for water level sensing.
As the water level rises it lifts the bottom float float 1 and closes it.
Automatic water level controller circuit.
Each sensors float is suspended from above using an aluminium rod.
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.
This relay s coil is also rated at 120vac so our water level control can switch it on off at rated voltage.
This sends current to the common com pin of the 12v relay.
Such sensors are more reliable than.
The second schematic shows how a pump up to 2hp can be wired for proper operation.
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.
Water level control s float switches work by using probes instead of float switches.
Let s start with the most basic float switch.
The water level is sensed by two floats to operate the switches for controlling the pump motor.
Float switches of the 21st century have come much further in the amount of operations your float switch can perform.
Taidacent pipeline high low water level sensor detection water tower box non contact level switch boiler auto water pump float switch water level controller 5m single probe 53 98 53.
This arrangement is encased in a pvc pipe and fixed vertically on the inside wall of the water tank.
Also all of the electronics are built into the head so you can.
Why a float switch.
