Vibration Type Level Switch - VLS Series. The blade of the probe vibrate on its resonance frequency. When filling material covers the blade of the probe, the vibration stops. This is sensed by the electronic circuitry and the output relay switches. When the blade gets uncovered, the vibration will restart and the relay will switch back.

Level Float Switches are simple in design and ruggedly built for long service dependability.

Side mounted liquid level switches are designed for horizontal mounting in a tanks or vessel through anged pipe connections. It is specially designed with an external test plunger mechanism.
