What ensures reliable flow measurement
under harsh process conditions?
SITRANS F M TRANSMAG 2 with SITRANS F M MAG 911/E sensor
perform with excellence under severe conditions with a strong
magnetic field.
Answers for industry.

Performance beyond the expected
Siemens supplies liners for every abrasive media applications and for optimal lifetime providing
best possible protection of the flowmeter. From inlet protection rings to liners and electrodes,
a wide range of materials are available. In particular, Linatex and PTFE liners have proven their
worth in harsh environments.
Linatex for top protection in mining applications
Rugged in design and unaffected by electrode noise,
disturbances or vibrations, the SITRANS F M TRANSMAG 2
flowmeter is ideal for anywhere with solid content and
magnetic particles up to 70%.
When fitted with a Linatex liner, the flowmeter is
well-equipped for wear resistance where the liner also
provides long-lasting mechanical protection as minerals
or particles bounce off the soft rubber liner, instead of
wearing it down.
Other liner options available are Neoprene and
NOVOLAK if chemicals are present - especially the
latter is well suited for gold processing.
Resistant PTFE liner for pulp and paper industries
The SITRANS F M TRANSMAG 2 flowmeter offers
exceptional value for pulp and paper applications.
The high-energy magnetic field generated with high
pulsed AC technology provides a powerful signal ideal
for measuring flow even where media fiber content
is up to 15%.
PTFE in general terms is renowned for possessing
the best long-term chemical resistance of any liner
material, maintaining its stability despite prolonged
exposure to high chemical concentrations at elevated
temperatures.
When equipped with a PFTE liner it is also well suited for
pulp and paper applications, and together with the good
signal noise relationship the SITRANS F M TRANSMAG 2
flowmeter is ready to take on your toughest requests -
no matter how demanding they may be.

Strong in every way
Siemens invention
The high-powered SITRANS F M TRANSMAG 2
flowmeter is an innovative Siemens invention
enabling accurate flow measurement even in
applications where slurries and solids are common.
The extremely robust flowmeter combines the
advantage of pulsed DC and the continuous
alternating field.
Superior magnetic field
The impressive magnetic strength of the
SITRANS F M MAG 911/E sensor is much greater
than conventional DC flowmeters. Besides the
strong magnetic field, the SITRANS F M TRANSMAG 2
offers a second coil circuit to compensate for
fluctuations in the magnetic field caused by the
conditions of the process. The result is a reliable and
accurate measurement with a fast response rate.

Nominal sizes DN 15 to DN 1000 (1/2“ to 40“)
Accuracy ± 0.5 % of flow rate
Rugged and reliable
In addition to high magnetic strength enabling superb flow
metering performance, the SITRANS F M TRANSMAG 2
flowmeter is also robust, equipped with a broad range
of attractive product features promoting long-term
reliability in severe conditions.
