Magnetic Liquid Level Indicators DESCRIPTION Magnetically coupled liquid level indicators, or MLIs, are in widespread use throughout process industries. Originally designed as an alternative to sight and gage glass devices, the MLI is now commonly used in both new construction and plant expansion as well as replacement for high maintenance sight and gage glasses. Orion’s Atlas, Gemini, and Aurora magnetic level indicators are precision engineered and manufactured to indicate liquid level accurately, reliably and continuously. These units are totally sealed chambers, that require no periodic maintenance; and, they eliminate vapor or liquid emission problems common with sight and gage glasses. To compliment these products, Orion produces a complete range of level switches and transmitters, including the Eclipse® Guided Wave Radar transmitter. F E AT U R E S • Countless chamber styles (or configurations) for each design • Complete range of level switches and level transmitters, including Eclipse Guided Wave Radar A P P L I C AT I O N S • Fabricated, non-magnetic chamber assembly produced in a wide range of metal and plastic materials • Feedwater heaters • Blowdown flash tanks • Industrial boilers • Hot wells • ANSI and DIN process connections • Oil water separators • Vacuum tower bottoms • Precision manufactured float with internal magnets and magnetic flux ring • Flash drums • Alkylation units • Surge tanks • Boiler drums • Gas chillers • Propane vessels • Deaerators • Storage tanks • Flag or shuttle type indicator with optional stainless steel scale to measure height, volume or percentage of level TECHNOLOGY Within the piping column of the magnetic level indicator is a float containing an internal set of magnets. A change of level 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 outside of the piping column in complete isolation from the process liquid is a visual indicator housing. It contains the customer’s choice of indicator (a series of flags or a follower). The individual flags or the follower contain an alignment magnet which couples to the float magnets as the float moves up or down the piping column. Refer to figure 1. This magnetic coupling rotates the flags and exposes the backs with their contrasting color or (in the case of the follower) moves the follower to the point of level. The position of the follower, or the point at which the flags change color, represents true level. Level measurement is indicated or “read” by the corresponding point on the measuring scale. Refer to figure 2.

Atlas is a single chamber design with either 2", 2.5", or 3" chamber diameter, as required by the application. There are twelve basic configuration styles including top mount models. Special configurations are also available. Atlas magnetic level indicators are produced in a wide range of materials of construction, including plastics. Orion also offers one of the most complete selections of process connection types and sizes in the industry. Atlas may be equipped with a variety of level transmitters and switches as well as flag and shuttle indicators with or without stainless steel scales. This enables the Atlas to be a complete level and monitoring control.

It is state of the art in this technology and reflects Orion’s innovation and commitment to magnetically coupled level indicators. 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.

Countless unique configuration styles are available with Gemini. It can be produced in the same metal material selections as Atlas. The second chamber facilitates the installation of any of a wide selection of transmitters to provide continuous level monitoring in addition to the indication provided by the primary chamber. Eclipse guided wave radar, direct insertion Jupiter magnetostrictive, or Kotron capacitance type level transmitters can be mounted in the secondary chamber to provide totally redundant indication with continuous level output. The primary chamber, which houses the float, can be fitted with clamp-on switches or transmitters for additional level control.

It is responsible for operating the indicator, switches and transmitters via interaction of the internal magnets and the magnets of various external indicators and clamp-on accessories. Precisely aligned vertical magnets Flux ring Manufactured from a wide range of alloys, including Titanium, the float is precision welded by a pulse TIG process. Within the float are high strength magnets precisely aligned and held in place with a retainer ring that assures a uniform 360° magnetic field and gauss rating. The magnets are designed for long term service even in elevated temperatures and pressures. Precision pulse TIG welded float Specific gravity data and serial number engraved on each float INDICATING SCALE Another option from Orion is a 316 stainless steel (standard) or plastic scale for displaying a wide range of engineering units of measure. This scale is mounted adjacent to the flag bar graph assembly or shuttle, and may be graduated to show height, volume, or percentage. The scales are available in either English or Metric units. Stainless steel scale with level units Flag type indicating scale Shuttle type indicating scale TEMPERATURE OPTIONS HIGH Magnetic level indicators can be ordered with several different tracing options to heat the external chamber. Tracing systems sometimes require that a special insulation blanket (custom designed to meet the customer’s specifications) cover the entire chamber and tracing equipment. Refer to pages 5, 12, 17, or 22 for temperature guidelines. Frost extension LOW To facilitate operation where the product is kept cold via chillers, refrigerants and condensers, a frost extension option and low temperature insulation are offered. The frost extension is constructed of durable acrylic plastic and suitable for contact with media as cold as -320° F (-196° C) such as liquid nitrogen.
