A water level float switch is a device used to sense and even control water levels in a water tank, reservoir, or any other similar storage facility. They are configured to trigger alarms or send signals if the water levels are not in keeping with the desired levels, and there are distinct ways that they do that based on the way they are designed.

The History of Float Switches

Vertical float switches in the past were relatively less efficient in their functioning and operated by controlling the open/close status of a circuit. A float attached to the switch, hollow from inside, floated over the water and operated as a magnet.

As the water levels fell, the reed float too would gravitationally fall with the water, disconnecting the magnets and opening the switch, allowing the water to continue to enter. A filled-up tank would have a raised and connected float due to its magnetic nature, and thus a closed switch, signifying that the water levels are up to the mark.

The Current Status of Float Switches 

With the recent developments made in the industry, the potential of liquid level float switches is greatly realized and put to use with the usage of probes rather than switches to sense the water levels. In this mechanism, there is not an additional liquid level sensor attached to the device that acts as the detector itself.

These probes are conditioned to set off alarms and signals based on distinct water levels that can command the operator or the program itself to either start the water fill up, stop it, or indicate if the water levels are too high or too low. They are configured to trigger alarms or send signals if the water levels are not in keeping with the desired levels, and there are distinct ways that they do that based on the way they are designed.

Liquid level float switches have entered the new era with the ability to control and program water levels to increase or decrease even without an operator to continuously monitor the process via multi-point switches. The efficiency they operate with is truly commendable.
