Aurora® Magnetic Level Indicator

Product Description:

Aurora® combines the traditional buoyancy-based Magnetic Level Indicator (MLI) with the advanced Eclipse® guided wave radar transmitter. The result is redundancy in true level measurement within a single chamber.

Applications:

Chemical, Crude Oil, Renewable Energy, Natural Gas Processing, Nuclear Power

Features:

(1) Eclipse guided wave radar transmitter;

(2) Wide range of outer chamber types;

(3) Non-magnetic outer chamber construction;

(4) ASME and DIN flanges;

(5) Precision-manufactured float;

(6) Flag or float indicators.

Working Principle:

The Aurora Magnetic Level Indicator (MLI) is a hybrid instrument that utilizes both buoyancy and guided wave radar measurement principles within the same chamber. The MLI relies on a magnetic float moving up and down with the liquid level inside a chamber connected to a pressure vessel or storage tank. The float contains a magnetic assembly that interacts with an externally mounted visual indicator panel. As the float follows the liquid, the magnetic field causes highly contrasting flags to rotate in the visual panel, displaying a highly visible level. In the Aurora, the float and guided wave radar probe are separated by a perforated baffle, creating two distinct measurement zones within the chamber. This provides a redundant level of instrumentation while minimizing overall footprint and weight. The MLI's functionality is extended through magnetically actuated external point switches and level transmitters, providing high or low alarms and real-time level data to the control room (4-20mA, HART, FF fieldbus).
