1100 Series
Magnetic Level Indicator
General Instructions
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.
NOTE: If you suspect that a product is defective, contact the factory or the SOR Representative
in your area for a return authorization number (RMA). This product should only be installed by
trained and competent personnel.
Installation
MOUNTING
Before assembling Level Gauge to your process, check for the following:
Vessel nozzles should be checked for horizontal and vertical alignment.
Vessel nozzles must be straight and even, with no bends.
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
program are necessary to ensure satisfactory service.
Design and specifications are subject to change without notice.

WHAT TO DO
Keep your Level Gauge clean inside and out.
If you have solids/debris in your process, or if it tends to build up on equipment,
it will be necessary to flush the gauge periodically. How often or thoroughly will
depend on the nature of your process liquid. It is important that the float can
move freely inside the chamber.
If you have an externally mounted transmitter or alarm switch, it is important
that all covers and conduit seals are in place and maintained. Moisture, dust
and debris entering these electronics housings can cause permanent damage,
leading to failure.
Inspect the float, terminals and connections monthly.
Remove the float from the chamber once a month to check for leaks or damage.
Clean the float and reinstall it. Proper float function is critical to the operation of
your level gauge.
Check electrical terminal connections and wiring for signs of damage due to
heat or vibration. Excessive heat can cause wire insulation to become brittle and
crack or fall off. Exposed wire can cause shorts or sparks, creating a dangerous
situation. Excessive or constant vibration can cause terminal screws to loosen,
creating intermittent or lost connections. Check that all electrical connections
are tight and wires are flexible with no signs of heat damage.
WHAT TO AVOID
Do not leave transmitter or alarm switch covers off longer than necessary to
inspect or maintain wiring and connections.
Make sure the float is installed correctly in the chamber. Do not install the float
upside down.
Do not attempt to make adjustments to attached transmitters other than Zero and
Span adjustments. Consult the factory for additional assistanace.
