AURORA® Magnetic Level Indicator


Aurora combines the operating system of a conventional float-based MLI with the leading-edge Eclipse Guided Wave Radar transmitter developed for level measurement applications by Magnetrol. The result is true level-measurement redundancy in a single-chamber design. Using a 3" or 4" chamber to house both the Eclipse coaxial style probe and the float, these devices operate seamlessly to provide continuous electronic Guided Wave Radar measurement and visual indication. There are six basic configuration styles, and over fifteen material selections for the Aurora. For the first time ever, the ability to accurately and repeatedly measure ultra low dielectric media, high temperature/high pressure process conditions, and media with shifting and changing dielectric values can be accomplished with Aurora.

Measurement Principle


Change in the process tank level corresponds to change within the Aurora chamber. The float within the chamber actuates flags or a shuttle for visual indication while the Eclipse® GWR transmitter provides continuous electronic level measurement.

Technology of the Aurora® Magnetic Level Indicator


The appeal of magnetic level indicators is total isolation of the process within a sealed piping column. Elimination of leaking seals, clouded glasses, broken glass tubing, plus easy access cleaning and adaptation to a variety of mounting styles and process connections. Availability of switches and transmitters adds to their desirability by providing a much less expensive system than a buildup of sight glasses, alarm switches and transmitters, all separately piped to the vessel.
Aurora is a totally redundant system of continuous level monitoring and control. An Eclipse guided wave radar coaxial probe is housed along with the MLI float in a 3" or 4" diameter chamber. While the indicator relies upon the float and its internal magnets to activate the flags or shuttle, the Eclipse measures the liquid level directly. Two completely separate technologies in a single external chamber ensure redundancy unlike any other MLI. The use of a baffle within the chamber ensures that the float and eclipse coaxial probe work seamlessly within the single chamber.
There are six basic configuration styles and over fifteen material selections for Aurora. For the first time ever, the ability to accurately and reliably measure ultra low dielectric media, high pressure/high temperature process conditions, and media with shifting and changing dielectric values can be accomplished with Aurora.
