Aurora Magnetic Level Indicator

Brand: Orion Instruments

Aurora’s patented design is the next generation of magnetic level indicators. It is state of the art and reflects Orion’s innovation and commitment to magnetic level indicators. Aurora is a totally redundant monitoring and control system. Liquid levels are tracked with great accuracy using two different technologies.

An Eclipse® guided wave radar 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 equal redundancy unlike any other MLI.

The use of a special baffle within the chamber ensures that the float and Eclipse® probe work seamlessly and without interference. There are ten 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.
