SOR 1100 Series Magnetic Level Indicators - Manual

Form 1597 (09.14) ©SOR Inc. 1/4
The 1100 Series Magnetic Level Indicator from SOR ® represents best
in class performance and value thanks to decades of experience and
innovation. Each unit is custom engineered for your exact application
and manufactured to our rigorous quality standards. SOR level gauges
are an ideal replacement for existing process sight gauge systems and
can easily become a functional bridle system for use with level switches,
transmitters, and temperature measurement.
The 1100 Series provides visual indication of liquid level within a larger,
primary process vessel. Once the MLI is mounted to the process vessel
via the supplied process connections, the process liquid will flow freely up
and down within the MLI chamber. A specially designed float is located
inside the 1100 Series chamber and floats along with the process level.
This float contains a powerful magnet that interacts with the non-invasive
indicator assembly located on the outside of the chamber. This magnetic
coupling between the float and the indicator allows the process level to be
shown via the use of rotating flags housed inside the assembly. As the
level rises and falls, these flags will change color and provide real time
indication of the liquid level within the primary process vessel.

 Center-to-center distance of gauge and vessel nozzles must match.
 Vessel and gauge nozzles should be free of sediment, dust and rust.
PREVENTIVE MAINTENANCE
Periodic inspection will keep your level gauge operating properly for many years.
These gauges provide visual level indication on critical services, and a systematic
program of preventative maintenance will provide excellent long-term protection. Close
attention to the following “what to do” and “what to avoid” tips in your maintenance
