Description
3.2 Theory of operation
12
The SITRANS F M MAG 5100 W sensor housing and flanges are designed in carbon steel
and terminal box in fibre glass reinforced polyamide. Measuring pipe is made of stainless
steel (AISI 304) and liners are available in NBR Hard Rubber, Ebonite Hard Rubber, or
EPDM, which makes the sensor highly resistant to a wide range of chemicals. Electrodes are
made of Hastelloy.

3.2 Theory of operation
The flow measuring principle is based on Faraday’s law of electromagnetic induction.

Description
3.2 Theory of operation
13
Ui = When an electrical conductor of length L is moved at velocity v, perpendicular to the
lines of flux through a magnetic field of strength B, the voltage Ui is induced at the ends of
the conductor
Ui = L x B x v
● Ui = Induced voltage
● L = Conductor length = Inner pipe diameter = k1
● B = Magnetic field strength = k2
● v = Velocity of conductor (media)
● k = k1 x k2
Ui = k x v, the electrode signal is directly proportional to the fluid velocity
Operating principle
The coil current module generates a pulsating magnetizing current that drives the coils in the
sensor. The current is permanently monitored and corrected. Errors or cable faults are
registered by the self-monitoring circuit.
Input circuit amplifies the flow-proportional induced voltage signal from the electrodes. The
input impedance is extremely high: >1014 Ω which allows flow measurements on fluids with
conductivities as low as 5 µS/cm. Measuring errors due to cable capacitance are eliminated
due to active cable screening.
Digital signal processor converts the analog flow signal to a digital signal and suppresses
electrode noise through a digital filter. Inaccuracies in the transmitter as a result of long-term
drift and temperature drift are monitored and continuously compensated for via the self-
monitoring circuit. The analog to digital conversion takes place in an ultra low noise ASIC
with 23 bit signal resolution. This has eliminated the need for range switching. The dynamic
range of the transmitter is therefore unsurpassed with a turn down ratio of minimum 3000:1.

Installing/Mounting
SITRANS F flowmeters with minimum IP67/NEMA 4X enclosure rating are suitable for in-
and outdoor installations.
● Make sure that pressure and temperature specifications indicated on the device
nameplate / label will not be exceeded.
WARNING
Installation in hazardous location
Special requirements apply to the location and interconnection of sensor and
transmitter. See "Installation in hazardous area" (Page 9)
4.1 Installation safety precautions
WARNING
In applications with working pressures/media that can be dangerous to people,
surroundings, equipment or others in case of pipe fracture, we recommend that special
precautions such as special placement, shielding or installation of a security guard or a
security valve are taken when the sensor is mounted.
● Ensure that stresses and loading caused by e.g. earthquakes, traffic, high winds and fire
damage if appropriate are taken into account during installation.
● Ensure that the flowmeter is installed such that it does not act as a focus for pipeline
stresses. External loadings are not taken into account in the flowmeter design.
● Provide adequate protection to minimise any risk of contact with hot surfaces.
WARNING
Prevent personal injuries by assuring that operation below pressure guards cannot take
place, if working with vacuum or fluids boiling readily.

4.2 Determining a location
NOTICE
The sensor must always be completely filled with liquid.
● Locate the the flowmeter in u-shaped pipes if pipes are only partially filled or have free
outlet
Figure 4-1 Correct installation in U-tube
● Avoid the following installations
– Installation at the highest point in the pipe system
– Installation in vertical pipes with free outlet
Figure 4-2 Correct installation with filled pipes
Figure 4-3 Correct installation at low point in system before outlet
Inlet and outlet conditions
To achieve accurate flow measurement it is essential to have straight lengths of inlet and
outlet pipes and a certain distance to pumps and valves.
It is also important to centre the flowmeter in relation to pipe flanges and gaskets.

4.2 Determining a location
17
Figure 4-4 Inlet and outlet conditions
Installation in large pipes
The flowmeter can be installed between two reducers (e.g. DIN 28545). At 8° the following
pressure drop curves apply. The curves are applicable to water.
Example:
A flow of 3 m/s (V) in a sensor with a diameter reduction from DN 100 to DN 80 (d1/d2 = 0.8)
gives a pressure drop of 2.9 mbar.

Installing/Mounting
4.3 Orienting the sensor
18
4.3 Orienting the sensor
The sensor operates in all orientations, but Siemens has the following recommendations:
● Vertical installation with an upwards flow
Figure 4-5 Vertical orientation, upwards flow
CAUTION
Abrasive liquids / liquids containing solid particles
A vertical installation minimizes wear and deposits in the sensor
NOTICE
Gas/air bubbles in the liquid
A vertical installation minimizes any negative effect of gas/air bubbles in the liquid
● Horizontal installation, terminal box upwards or downwards
Figure 4-6 Horizontal installation, various terminal box positions
CAUTION
Do NOT mount the sensor with the terminal box sideways
This will position the electrodes at the top where there is possibility for air bubbles and
at the bottom where there is possibility for mud, sludge, sand etc.
NOTICE
Empty pipe detection
For applications with empty pipe detection, the sensor can be tilted 45°, as shown
above.
