Description

3.1 Overview
SITRANS F M Transmag 2 is a pulsed alternating field magnetic flowmeter where the
magnetic field strength is much higher than conventional DC pulsed magnetic flowmeters.
This makes it ideal for difficult applications as:
● High concentrated paper stock > 3 %
● Heavy mining slurries
● Mining slurries with magnetic particles
The complete flowmeter consists of a flow sensor 911/E and the associated SITRANS F M
Transmag 2 transmitter.
Transmag 2 is available in a remote or a compact version. The 911/E sensor is available
with diameters from DN 15 to DN 600 (½" to 24").
As a standard protective washers are fitted permanently on all PTFE-coated sensors to
protect the coating.
3.2 Operating principle
SITRANS F M Transmag 2 is a microprocessor-based transmitter with a built-in
alphanumeric display in several languages. The transmitters evaluate the signals from the
associated electromagnetic sensors and also fulfil the task of a power supply unit which
provides the magnet coils with a constant current.
The magnetic flux density in the sensor is additionally monitored by reference coils. Further
information on connection, mode of operation and installation can be obtained from the
sensor data sheets.

– Simulation of output signal via analog output, digital output 1 and digital output 2
– Option: digital output 2 as digital input for resetting counter values or for interruption in
measurement (PZR)
3.4 BUS Communication
SITRANS F M Transmag 2 is available with HART or PROFIBUS communication.
● The HART protocol is superimposed on the analog output (current output). This
communication capability permits parameterization of the device using the HART
communicator or a PC/laptop and SIMATIC PDM software in addition to local operation.
● In the PROFIBUS PA version, the analog output and the digital output 2 are replaced by
the digital PROFIBUS PA output. Parameterization of the device is then possible using
PROFIBUS communication and SIMATIC PDM in addition to local operation.

4.1 General Information
This chapter describes how to install the flowmeter in the compact version as well as in the
remote version.
CAUTION
The device meet the requirements of IP67 degree of protection. Proper installation is a
prerequisite for compliance with this degree of protection. Please observe the instructions
in this chapter.
The maximum permissible ambient and medium temperatures must be observed at all
times.
The measuring tube should be filled exclusively with media to which the seal and lining
materials are chemically resistant. Only conductive media are permissible.
WARNING
If the surface of the sensor or sensor tube can get hotter than 50 ºC in the application, fire
protection and/or a warning sign must be provided.
CAUTION
Make sure the measuring device is protected from direct sunlight when installing it
outdoors.

4.2 Sensor installation

4.2 Sensor installation
The measuring principle is generally independent of the flow profile unless static eddy
currents penetrate the measured value forming zone (e.g. after pipe elbows, in the case of
tangential occlusion or half open slides in front of the sensor). Measures to normalize the
flow profile are necessary in such cases. Suitable measures in this respect are:
● increasing the inlet and outlet lines
● using flow rectifiers
● reducing the line cross section
CAUTION
It is recommended to use protective rings (orifice protectors) to protect the inlet and
outlet edges of the sensor against mechanical damage especially when used with
abrasive media.
Protective rings are available as accessories.

Sensor location
Do not install the sensor in pipe sections with a free pipe outlet which could run empty. When
installing in a downpipe, make sure that the pipe is always filled 100% with the medium

Figure 4-4 Installation at the highest point
Install the flowmeter so that the measuring pipe cannot run empty and is always filled with
medium.
The sensor must be installed in a culvert in the case of an unfilled pipe or only a free level
line (outlet).

Line cross sections
By reducing line cross sections you have the possibility of installing smaller sensors in pipes
of larger rated widths.
This has the advantage that the speed in the sensor increases with small flows and thus a
better measuring accuracy is achieved.
To avoid the formation of eddy currents in the sensor, the angle of reduction should not be
greater than 8°.

4.2.1 Potential equalization of sensor (refence potential)
The sensor must be at the same potential as the medium for an accurate measurement.
This is guaranteed when the connecting flange of the pipe is made of metal and a perfect
electrical connection is established to the sensor through the fastening screws. In this case
the medium, pipe and transmitter are connected with each other in the sense of a potential
equalization.
Figure 4-7 Reference potential in electrically conductive pipes
In the case of internally electrically isolated pipes, the medium in the pipe must be applied to
a reference potential by additional measures (e.g. by grounding rings). Grounding rings
serve to establish the reference potential of the sensor in electrically isolated pipes.

Grounding rings are offered as accessories.

WARNING
The pertinent regulations must be observed for electrical installation.
Never install the device with the mains voltage switched on!
Danger of electric shock!
The electrodes and magnetic current line may only be connected when the device is not
connected to the power supply.
Housing covers may only be unscrewed by qualified personnel when the housing is under
voltage (power supply).
Cable specifications
● Only use cables with at least the same degree of protection as the sensor to install the
sensor.
● The line length from the cable gland to the terminals must be kept as short as possible.
Line loops in the terminal box must be avoided.
● To guarantee the IP 67 degree of protection, use cables with the following external
diameters:
The permissible external diameter for auxiliary power and signal cable (large terminal
box) of the standard device (7ME5034-xxxxx-xAA0) is 6 to 12 mm.
Magnetic field current and electrode cable (small terminal box, only remote model):

5.2 Step 1: Connecting power supply
CAUTION
Only connect the device to the supply which matches the specifications on the rating plate.
Connect the power supply by an easily accessible and appropriately labelled isolating
device and fuse (max. 4 A) or an easily accessible circuit breaker (max. 4 A).
Note
Use cables with a cross section of at least 1.5 mm

and double or reinforced insulation for
the power supply.
Wiring guidelines
1. Release the catch on the lid of the terminal box using a 3 mm Allen key.
2. Unscrew the lid of the terminal box.
3. Push the supply cable through the cable glands up to the terminal strip. Lay the cable in a
loop before the cable glands so that moisture does not get inside the terminal box.
4. Connect the lines according to the figure below.
① Ground connection for signal cable shield
② Digital output 2 (relay) or digital input
③ Digital output 1 (active/passive)
④ Analog output (active) 4 to 20 mA resp. PROFIBUS

5.3 Step 2: Connecting signal cables
CAUTION
Lay the signal cables separately from cables with voltages > 60 V.
Avoid laying signal cables close to large electrical installations or use - if possible - only
shielded cables.
Note
In a wet environment, the signal cable for digital output 2 (terminals 3 and 4) must be
isolated when the feed-in voltage is more than AC 16V / DC 35 V.
Only use signal cables with twisted wire pairs.
1. Push the signal cable through the cable gland up to the terminal strip. Lay the cable in a
loop before the cable glands so that moisture does not get inside the terminal box.
2. Connect the lines according to the figure above.
3. Fit end ferrules to fine-wire lines.
4. Tighten the cable gland and check strain relief.
5. Screw the lid to the housing and tighten it. You must not use any tools. The sealing ring
must be clean and undamaged.
6. Mount the lid catch.
7. For transmitters in remote design, also connect the housing to the local potential
equalization to which the appropriate sensor must also be connected.
HART requirements
● The full HART 5.1 specification only applies when using shielded cables.
● Use signal cables with twisted wire pairs if the analog output and pulse/frequency output
are used simultaneously and signals are transmitted in one cable.
● A load of at least 250 Ω must exist in the signal circuit (see also Technical data
(Page 73)) for error free communication via the HART protocol.
