Magnetic level indicators

Magnetic Level Indicators (MLI) have revolutionized the global visual indication market by offering a safer, reliable, and high-visibility alternative to common gauge glass assemblies.  Utilizing a combination of proven buoyancy principles along with the benefits magnetism, MLIs can be customized to fit virtually any process connection arrangement on the vessel.

The chamber and magnetic float is available in a variety of materials and pressure ratings to accommodate the wide variety of complex process applications present in the world’s major industrial facilities.

All of our products are engineered and manufactured in accordance with the applicable global and regional design standards required, including ASME , PED, CRN, EAC (Gost), and other.

Atlas™ principle of operation

Within the ATLAS chamber is a float containing an internal group of magnets. A rise or fall of the fluid in the process tank corresponds to a similar change within the piping column. In response to the level movement the float moves up or down accordingly.

Clamped to the piping column in total isolation from the process liquid is a visual indictor housing. It contains the choice of indicator, either a series of flags or a follower (also known as a shuttle).

The individual flags or the follower contain an alignment magnet that couples with the float magnets as the float moves up or down within the piping column. Float movement rotates the flags and changes their color, or in the case of the follower moves the follower to the point of level.

The position of the follower, or point at which the flags change color, represents true level. Level is indicated or "read" by the corresponding point on the measuring scale.

Aurora® principle of operation

The AURORA magnetic level indicator combines the operating system of a conventional float-based magnetic level indicator (ATLAS) with the leading edge Eclipse® Guided Wave Radar transmitter. Since the signal from the ECLIPSE transmitter is carried within a waveguide, process conditions that hamper other measurement technologies have virtually no effect on the ECLIPSE unit's accuracy and reliability.

The result is true level-measurement redundancy in a single-chamber design.

Gemini principle of operation

Gemini combines the operating system of a conventional float-based MLI (Atlas) and provides a second chamber for the installation of an additional liquid level measurement device such as an Eclipse Guided Wave Radar transmitter.  The design can easily be customized to include isolation valves between each of the chambers.  With valves in place, one chamber can be taken out of service for scheduled maintenance while the other chamber continues to operate normally.
