Jerguson® Mini-Magnicator ™ 

Light Duty Magnetic Level Gage | Superior Visibility, Compact Design

Models Beginning With: MII-15B
The Mini-Magnicator is specifically designed for the light duty industrial market. These versatile and economical level devices can be utilized in a variety of applications.

How It Works
The Magnetic Level Gage chamber contains a float, with magnets, that rises and falls as liquid level changes in the storage vessel. The float is magnetically coupled to the external indicator, whose flags rotate to indicate level, as the float travels by. The updated design utilizes the Jerguson patented magnetic arrangement for superior reliability.

The Magnet Matters!

Jerguson uses a unique float construction with 360 degree ring magnets with north poles opposing. This yields a strong focused magnetic field which eliminates skipped flags and provides reliable activation of switches and transmitters.
