46-138.2 MLI Sales - Magnetrol International

Atlas, Aurora, &
Gemini Magnetic
Liquid Level Indicators
DESCRIPTION
Magnetically coupled liquid level indicators, or MLIs,
are in widespread use throughout the process
industries. Originally designed as an alternative to sight
and gage glass devices, the MLI is now commonly used
in both new construction and plant expansion as well
as replacement for high maintenance sight and gage
glass.
Magnetrol’s Atlas, Gemini, and Aurora magnetic level
indicators are precision engineered and manufactured
to indicate liquid level accurately, reliably and
continuously. These units are totally sealed chambers,
that require no periodic maintenance; and, they
eliminate vapor or liquid emissions problems common
with sight and gage glasses.
To compliment these products, Magnetrol produces a
complete range of level switches and transmitters,
including Eclipse® Guided Wave Radar Transmitter.

TECHNOLOGY
Within the piping column of the magnetic level indicator
is a float containing an internal group of magnets. A
change of level in the process tank corresponds to a
similar change within the piping column. In response to
the level movement, the float moves up or down
accordingly.
The individual flags or the follower contain an alignment
magnet which couples to the float magnets as the float
moves up or down the piping column. Refer to figure 1.
This magnet coupling rotates the flags and changes their
color–or in the case of the follower–moves the follower
to the point of level.
Clamped to the piping column in complete isolation from
the process liquid is a visual indicator housing. It contains
the customer’s choice of indicator (a series of flags or a
follower).
The position of the follower, or the point at which the
flags change color represents true level. Level
measurement is indicated or “read” by the corresponding
point on the measuring scale. Refer to figure 2.

The Atlas is Magnetrol’s standard, high performance
magnetic level indicator. Atlas is a single chamber
design with either 2", 2.5", or 3" chamber diameter, as
required by the application. There are twelve basic
configuration styles, including top mount models.
Atlas magnetic level indicators are produced in a wide
range of materials of construction, including plastics.
Magnetrol also offers one of the most complete
selections of process connection types and sizes in the
industry.

AURORA
Aurora is the next generation of Magnetic Level
Indicators. It is state of the art in this technology and
reflects Magnetrol’s innovation and commitment to
magnetically coupled level indicators.
Using a 3" or 4" chamber to house both the Eclipse
coaxial style probe and the float, these devices operate
seamlessly to provide continuous electronic Guided
Wave Radar measurement and visual indication.
There are six basic configuration styles, and over fifteen
material selections for the Aurora.
For the first time ever, the ability to accurately and
repeatedly measure ultra low dielectric media, high
temperature/high pressure process conditions, and
media with shifting and changing dielectric values can
be accomplished with Aurora.

GEMINI
Magnetrol’s twin chamber design is unique to the
Magnetic level gauge industry. Over 18 unique
configuration styles are available with Gemini, and
though not available in plastics, it may be produced in
the same metal material selections as Atlas.
The second chamber facilitates the installation of the
Eclipse Guided Wave Radar Transmitter. This provides
for a totally redundant measurement system. With a
standard magnetic indicator and a side clamp-on
transmitter, the float represents a single point of
indication. If the float should become damaged due to
violent process conditions, the signal from the analog
transmitter is lost. With the dual chamber design,
Eclipse will continue to measure the liquid level
accurately, repeatedly and reliably, as it is not
dependent on interaction with the float.
Gemini’s magnetic indicator chamber can be equipped
with switches, transmitters, blankets or heat tracing,
while the secondary chamber houses the electronic
measurement instrument.

FLOAT
The float is the key to the magnetic level gauge
operation. It is responsible for operating the indicator,
switches and transmitters via interaction of the internal
magnets and the magnets of various external indicators
and clamp on accessories.
Precisely aligned
vertical magnets
Flux ring
Manufactured from a wide range of alloys, including
Titanium, the float is precision welded by either a pulse
TIG process or Electron Beam process. Within the float
are high strength magnets, precisely aligned and held in
place with a magnetic flux ring (patent pending) that
assures a constant 360° magnetic field and gauss rating.
The magnets are designed for long term service even in
elevated temperatures and pressures.

SCALE
Another option from Magnetrol is a stainless steel scale
for display of a wide range of engineering units of
measure. This scale is mounted adjacent to the flag bar
graph assembly or shuttle, and may be produced to
show height, percentage of level, volume, or volume.
The scales are available in either English or Metric
units.

OPTIONS

Magnetic level indicators can be ordered with several
different tracing options to heat the external chamber.
Tracing systems require that a special blanket (custom
designed to meet the customers specifications) cover
the entire chamber and tracing equipment. Refer to
page 11 for temperature guidelines.
Frost extension
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 -320° F (-196° C) such as liquid nitrogen.
