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 build up 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. |
