ATLAS™ ® Magnetic Level Indicators Atlas™ is a product of Orion Instruments, a Magnetrol company DESCRIPTION Atlas™ is a high performance magnetic level indicator (MLI) for level, interface or level and interface measurement. Atlas™ is a single chamber design available in twelve basic configuration styles, including top mount models. Atlas MLIʼs offer a wide choice of materials of construction, process connections and sizes. Only the most popular choices are published. Consult factory for choices not listed in this bulletin. Atlas™ may be equipped with the external mount Jupiter®, magnetostrictive transmitter; consult bulletin BE 46-138, or with an Eclipse® Guided Wave radar in an enlarged cage; consult Eclipse Aurora® bulletin BE 57-138. The basic MLI version of Atlas™ is Vizual®; consult bulletin BE 46-137. 12 Configuration styles F E AT U R E S • Precision manufactured float with multiple magnets and flux ring for an optimum Gauss rating. • Indication rail filled with inert gas for elimination of condensation and a clear read off under all conditions. • Rubber seal protects the glass of the indicator against heavy vibration and handling. • Flags are designed with mechanical stop for stable indication of fast varying level changes. • Shuttle followers for level and interface indication. • Stainless steel flags in aluminium or stainless steel (optional) indication rail. • 1/2" NPT vent and drain. • Max hydrotest pressure of the float: 62 bar (900 psig) higher pressure at request. • Min operating process temperature: -50 °C (-60 °F) standard, down to -196 °C (-320 °F) at request. • Max operating process temperature up to + 540 °C (up to +1000 °F) with factory supplied insulation. • S.G. range as low as 0, 49 kg/dm3 (lower S.G. at request). • Bottom and top spring protection of the float avoids float damage during transport, maintenance and surging/ flashing conditions. • Options: - high and low temperature options - stainless steel scale for level or volume - Jupiter magnetostrictive transmitter. A P P L I C AT I O N S MEDIA: Clean liquids with a density ≥ 0,49 kg/dm3 incl. aggressive, toxic and flammable liquids / liquified gases. VESSELS: Most process and storage tanks up to rated operating pressure and process temperature. FUNCTION: Continuous liquid level or liquid-liquid interface indication.

Worldwide level and flow solutions P R I N C I P L E O F O P E R AT I O N The MLI (Magnetic Level Indicator) consists of a sealed bypass cage, a float containing a magnet and a visual indicator rail with bi-coloured flags that individually contain a magnet. The indicator rail is external mount on the cage and its flags are magnetically coupled/aligned with the magnet of the float. As the level changes, the float will follow and its magnet will attract the magnets in the flags. This will cause the flags to rotate showing their opposite coloured side. The same electro-magnetic coupling will activate/deactivate switches or change the output of an externally clamped on magnetostrictive transmitter. Flux ring Stainless Steel chamber wall Liquid level Indicating flags Float magnet Float JUPITER® Jupiter magnetostrictive transmitters are very accurate level transmitters that can be externally mounted onto an Atlas MLI. The unit generates a low energy pulse that travels over the length of the magnetostrictive wire inside the guide tube of the transmitter. A return signal is generated from the precise location where the electro-magnetic field of float of the Atlas MLI intersects the wire. The unit measures the time-of-flight of the return signal and converts the liquid level, interface level or both levels to a mA output signal. Jupiter is compatible with HART®, AMS, PACTware™-FDT and FOUNDATION™ Fieldbus communication. The transmitter is not affected by process variables and can be easily removed/ installed under operating conditions. For more details – consult bulletin BE 46-148. AURORA™ Aurora® is the innovative combination of the Eclipse® Guided Wave Radar and a Magnetic Level Indicator (MLI). The MLI indicator rail offers the Eclipse a highly visible level indication that may obsolete the need for local indicators. The integration of these two independent technologies provides an excellent redundancy in one integrated design. With Aurora®, it is even possible to plan maintenance ahead. Maintenance becomes needed when buildup in an installation has surpassed the allowable limit. Buildup on the float inside the MLI cage will force it to sink deeper in the liquid while the measurement of the Eclipse will not see any buildup until its both lead elements are completely clugged. In this way, the float will indicate a lower level versus the real level measured by the Eclipse. The degree of deviation between both read outs is a worthwhile tool to determine the real need for maintenance. For more details – consult bulletin 57-138. T E M P E R AT U R E O P T I O N S 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 customerʼs specifications) cover the entire chamber and tracing equipment. 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 -196 °C (-320 °F) such as liquid nitrogen. 2 Frost extension Low temperature blanket F L O AT Precisely aligned vertical magnets 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.

This scale is mounted in adjacent to the indication rail and shows level, volume or % of span. Custom-made scales are available at request. Two types of indicators exist: flags or shuttles. The flags are SST and available in 3 bi-colour options: red/white, black/ orange or Black/yellow. The orange shuttles are strictly used for dual measurement (level and interface) applications. Stainless steel scale with level units Flag type indicating scale Top float stop spring AT L A S The Atlas MLI is a premium gauge with many standard features on board.
