Atlas_MLIs.pdf

Designed as an alternative and upgrade to sight gauge devices, Magnetic Level Indicators (MLI) from Orion Instruments® are manufactured to reliably and continuously provide accurate liquid level in a wide range of applications. Our MLI product line—manufactured globally at multiple facilities—requires minimum maintenance and eliminates vapor or liquid emission problems, which are common with sight glass. Orion Instruments specializes in precision-engineered excellence and offers highly-customized configurations and options for process environments, including those with extreme temperatures and pressures.

The Atlas™ is the standard high-performance magnetic level indicator from Orion Instruments®. 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 options not listed in this bulletin.

The Atlas MLI is produced in a wide range of materials, including exotic alloys and plastics. Orion offers 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 MLI to be a complete level and monitoring control.

Float Projection Curve

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.

Orion 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.

Maximum capabilities can vary depending on combination of pressure, temperature, and media specific gravity.

HIGH-TEMPERATURE INSULATION

Orion specializes in custom fiberglass insulation blankets for MLIs of all shapes and sizes. They are constructed with high-quality materials capable of constant contact with temperatures up to 538 °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 Orion’s line of Magnetic Level Indicators. Particles composed mostly of ferrite, often from car-bon steel piping, are widespread throughout process piping. These particles enter the MLI via the process connections during normal fill and drain opera-tions. The magnetic float located inside the MLI attracts these particles over time. Eventually, the buildup 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 through-out harsh, cold conditions.

Electric Heat Tracing is available in self-regulating, constant wattage, and min-eral insulated varieties. Contact the factory for more information.

MOUNTING TO ATLAS – MODEL ORS

WIRING – MODEL ORS

Position the ORS switch on the MLI body so that the centerline of the stainless steel tube which houses the switch is at the desired switch point level. The switch should be oriented so that the green grounding screw is closest to the top of the MLI. Install the clamps around the MLI and over the mounting tabs of the switch. Tighten the clamps until the switch is firmly secured to the MLI. If required, place the insulation between the MLI body and the ORS switch before securing the clamps.

The switch leads are color coded as follows:

white = common black = normally closed (float below switch) red = normally open The wiring diagram shows both conditions of the switch relative to the float.

OPTIONAL EXTERNAL MOUNT LEVEL TRANSMITTERS

OCT reed chain transmitter 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 non-invasive.

OES bi-stable DPDT microswitch 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.

SELECTION DATA

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.
