MAGNETIC LEVEL INDICATOR ® Worldwide Level and Flow SolutionsSM DESCRIPTION FEATURES 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. • Numerous chamber styles (or configurations) are available for each design. Consult factory for choices not listed in this bulletin. 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 vapour or liquid emission problems common with sight and gauge glasses. • Fabricated, non-magnetic chamber assembly produced in a wide range of metal and plastic materials. • Complete range of level switches and level transmitters. • A wide range of process connections is available. • Precision manufactured float with internal magnets and magnetic flux ring. To complement these products, a complete range of level switches and transmitters is available. Combinations using Jupiter® (magnetostrictive technology) are also possible. • Flag or shuttle type indicator with stainless steel scale to measure height or percentage of level. The Atlas™ is our 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 several configuration styles including top mount models. Consult factory for choices not listed in this bulletin. • Exceptional code qualified welding. ATLAS MLIs are produced in a wide range of materials, including exotic alloys and plastics. We also offer the most complete selection of process connection types and sizes in the industry. ATLAS can 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. • Standard float stop springs at top and bottom of chamber.

This eliminates “overflipping” which is commonly seen on other indicator designs. Standard flag and shuttle offering. Custom colours available. 3 ORION FLOAT TECHNOLOGY Weld ring: Secures float cap to main body. Flux ring: Absorbs magnetic energy and directs it outward. Magnets: A full array surrounds the float with a strong and consistent magnetic field. The float contained within the magnetic level indicator is perhaps the most important element of the instrument. Its structural design, volume displacement, weight, and buoyancy force are all carefully considered when a float is specified for a particular application. Our engineers have designed and tested hundreds of floats to gather the most accurate data available. We have designs for thousands of unique applications around the world, including high pressure, high temperature and interface. Support ring: Provides reinforcement for the main float body. Float body: Robust and durable construction delivers many years of reliable operation. CAPABILITIES • Process pressures up to 310 bar (4500 psig). • Process temperatures up to 540 °C (1000 °F). • Total level specific gravities as low as 0,25. • Interface float designs available for liquid specific gravity differentials as little as 0,1. • Adequate buoyancy to operate effectively and freely in many viscous liquids, including crude oil. The float’s 360° magnet assembly produces a strong and consistent flux array allowing visual indication through chambers as thick as schedule 160. Float Immersion, mm (mm) 305 292 OPTIONS • Teflon-S® PTFE and PFA slip-assistant coating. • Halar® ECTFE coating for abrasion and chemical resistance. • Float retrieval hook. • Float immersion curve: If the liquid density changes, a float curve will reveal the offset. 279 267 254 241 229 216 Application Data (Information provided to Orion Instruments): Operating Temperature 215 °C (422 °F) Operating Pressure 24 bar (350 PSIG) Operating Specific Gravity 0.80 203 Calculated Data: Estimated Specific Gravity at 215 °C @ 24 bar (422 °F @ 350 PSIG) (Used SteamTab software) 191 Float immersion information: Length of float submersed in liquid at 0.80 SG Length of float submersed in liquid at 0.84 SG Length of float submersed in liquid at 1.00 SG 178 0.845 261 mm (10.281”) 250 mm ( 9.819”) 211 mm ( 8.308”) (SG) Float Immersion Example: Float immersion curve Maximum capabilities can vary depending on combination of pressure, temperature and specific gravity. 4 MAGNETIC LEVEL INDICATOR SPECIFICATIONS Design Single chamber Materials of construction – Chamber Metal alloys and plastics/composites: see selection table digit 5 Aluminium rail with polycarbonate or glass window, – Rail & window 316 stainless steel (reveal™) rail with polycarbonate window – Float 316 stainless steel and titanium (exotic alloys available); varies depending on process conditions Construction grade Industrial PED (metallic) or non-PED (plastic) Construction options Standard, ASME B31.1, ASME B31.3 and NACE Approvals Industrial PED units: ATEX II 1 G c T6 (non-electrical equipment) Certified material test report (CMTR) Available upon request Pressure class ratings ANSI 150#, 300#, 600#, 900#, 1500#, 2500# EN PN16, PN25, PN40, PN63, PN100, PN160, PN250, PN320 Process connection sizes 1/2" to 6" DN 15 to DN 150 Process connection types Flanged, threaded, butt weld, ...

They are constructed with high-quality materials capable of constant contact with temperatures up to 540 °C (1000 °F). This insulation is available as personnel protection or with heat tracing options for freeze protection or process temperature maintenance. CRYOGENIC INSULATION & FROST EXTENSION To facilitate operation where the product is kept cold via chillers, refrigerants, and condensers, cryogenic insulation is provided. By insulating the MLI with a specialized cryogenic jacket, process temperatures can be maintained in the liquid state down to -196 °C (-320 °F). A frost extension option is available to prevent ice from collecting on the visual indicator, thereby decreasing the visibility. The extension is constructed of durable acrylic plastic and is provided standard with all cryogenic insulation. MAGNETIC PARTICLE TRAP Magnetic particle traps, or magtraps, provide protection for our line of magnetic level indicators. Particles composed mostly of ferrite, often from carbon steel piping, are widespread throughout process piping. These particles enter the MLI via the process connections during normal fill and drain operations. The magnetic float located inside the MLI attracts these particles over time. Eventually, the build-up will be enough to cause the float to become stuck inside the chamber. This results in the MLI either reading inaccurately or not at all. The trap collects the particles which can be cleaned periodically to ensure continued operation of the magnetic level indicator. HEAT TRACING: ELECTRIC & STEAM For applications where process freeze protection or temperature maintenance is required, heat tracing will allow the MLI to operate uninterrupted throughout harsh, cold conditions. Electric heat tracing is available in self-regulating, constant wattage, and mineral insulated varieties.

Both types are mounted to the MLI via clamps. Jupiter magnetostrictive transmitter Refer to bulletin BE 46-148, chapter external mount Jupiter. OCT reed chain transmitter DESCRIPTION The OCT analog transmitter mounts directly to the side of the MLI and provides a continuous 4 - 20 mA output signal proportional to the liquid level. Using simple and reliable reed switches surface mounted to a printed circuit board, the unit provides a resolution of ± 13 mm (0.50"). Activated by the magnetic field of the float, the transmitter is totally noninvasive.

Aluminium housing 18 Stainless steel housing OPTIONAL POINT LEVEL SWITCHES The OES level switch is a cam-operated microswitch while the ORS level switch is a hermetically sealed reed switch. Both types can be mounted to the MLI either via clamps or attached to a switch mount rod and are field adjustable. Simply loosen the mounting clamps and position at the desired location. Ensure that the switch always remains in close proximity to the internal float. A switch mount rod is an available alternative method for mounting the switch to an MLI when chamber insulation blanket is present. The rod assembly, which is welded to the MLI chamber, allows the switch to slide along the full length. When the desired position is selected, simply tighten it in place. FLOAT OES switch attached to switch mount rod FLOAT ORS switch attached to switch mount rod 19 OES bi-stable DPDT microswitch DESCRIPTION The OES level switch is actuated by simple magnetic coupling. As the liquid level moves, the MLI float (with its internal magnets and flux rings) follows. When the float moves into the proximity of the microswitch, the switch magnet interacts with the float’s magnetic field actuating the switch. The bi-stable design of the switch ensures that it will not reset until the float passes the switch in the opposite direction.
