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.

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.

HIGH-TEMPERATURE INSULATION
Orion specializes in custom fibreglass insulation blankets for MLIs of all
shapes and sizes. 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. Contact the factory for more information.

MOUNTING TO ATLAS
Position the OES switch on the MLI body so that the centerline of the switch housing is at the desired switch point level.
Unscrew the housing cover and ensure that the switch is oriented so that the arrow on the internal mechanism is pointing toward the top of the MLI. Install the clamps around the MLI and over the mounting brackets on the top and bottom
of the housing. Tighten the clamps until the switch is firmly secured to the MLI. Replace the housing cover. If required,
place the insulation between the MLI body and the OES switch before securing the clamps.
WIRING
The lower cable entry is protected with a plastic plug. The
upper opening is sealed with a steel plug. If it is preferable
to wire through the upper cable entry, the steel plug may
be moved to the lower opening. The DPDT switch has two
sets of contacts. Refer to the wiring diagram or label on the
mechanism itself.

CHAMBER MODIFICATION FOR MOUNTING OF OPTIONAL SWITCHES AND/OR TRANSMITTER
ATLAS can be combined with various externally mounted accessories, including switches and transmitters. In these cases
minor changes to the chamber and float design may be required.
For digit 16, match up the MLI product with the appropriate transmitter, switch or combination of both.
For OES/ORS switch, refer to the switch selection data for temperature limitations and insulation options. Match up the
switch model code digit 7 with the MLI model codes 16 and 17.
For OCT transmitter, refer to digit 17 for temperature limitations and match up the OCT model code with the MLI model
codes 16 and 17.
For Jupiter transmitter, refer to digit 17 for temperature limitations and possible mounting configurations. Match up the
Jupiter model code with the MLI model codes 16 and 17.
If SIL enhanced Jupiter transmitter is required then use MLI model with float diagnostics indicator, refer to digit 18.
All transmitters and switches must be ordered separately.

OPTIONAL EXTERNAL MOUNT LEVEL TRANSMITTERS
The Jupiter transmitter is a magnetostrictive level transmitter while the OCT transmitter is a reed chain level transmitter.
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.

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.

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.
