* It can be attached to the top of chemical tank to check the chemical solution level.
* Prevent non-dosing of chemical solution by notifying when to replenish the chemical solution. (prevention of running out chemical solution)
* Prevention of pump dry run.
* There are variety mounting methods with reasonable cost.
* Made of PVC, high chemical resistance.

Principle

A magnet is built in the float and the reed switch is secured in the guide pipe. As the float with a magnet inside goes up and down, the reed switch turns on and off. This system is effective in providing alarms and controlling motors, solenoid valves, etc.
* When controlling motors, solenoid valves, etc. by use of TL, connect and control them through electromagnetic switches and/or auxiliary relays.
