oRion INSTRUMENTS a OMagnetior Company THE NEXT GENERATION OF MAGNETIC LEVEL INDICATION MAGNETIC 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 gauge glass devices, the MLI is now commonly used in both new construction and plant expansion. ORION INSTRUMENTS® Atlas, Gemini, and Aurora® magnetic level indicators are precision engineered and manufactured to indicate liquid level accurately, reliably, and continuously. These units are completely sealed and require no periodic maintenance. MLIs also eliminate vapor or liquid emission problems common with sight and gauge glasses. To complement these products, Orion produces a complete range of level switches and transmitters, including the Eclipse® Guided Wave Radar transmitter from Magnetrol International. FEATURES • Numerous chamber styles (or configurations) for each design. Custom designs available. • Complete range of level switches and level transmitters, including Eclipse Guided Wave Radar • Fabricated, non-magnetic chamber assembly produced in a wide range of metal and plastic materials • ANSI and EN 1092 process connections available • Precision manufactured float with internal magnets and magnetic flux ring • Flag or shuttle type indicator with stainless steel scale to measure height, volume, or percentage of level • Standard float stop springs at top and bottom of chamber • Exceptional code qualified welding APPLICATIONS • Feedwater heaters • Industrial boilers • Oil/water separators • Flash drums • Surge tanks • Gas chillers • Deaerators • Blowdown flash tanks • Hot wells • Vacuum tower bottoms • Alkylation units • Boiler drums • Propane vessels • Storage tanks

MAGNETIC LEVEL INDICATOR | OVERVIEW ATLAS & VECTOR MLI The Atlas is Orion’s standard high-performance magnetic level indicator. Atlas is a single chamber design with either a 2", 21⁄2", 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 MLIs are produced in a wide range of materials, including exotic alloys and plastics. Orion also offers the most complete selection of process connection types and sizes in the industry. Atlas can be equipped with a variety of level transmitters...
