Function and system design
Faraday’s law of induction states that a voltage is induced in a conductor moving in a
magnetic field.
In electromagnetic measuring, the flowing medium corresponds to the moving
conductor. The induced voltage is proportional to the flow velocity and is detected by
two measuring electrodes and transmitted to the amplifier. Flow volume is computed
on the basis of the pipe’s diameter.The constant magnetic field is generated by a
switched direct current of alternating polarity.
Ue = B · L · v
Q = A · v
Ue = induced voltage
B = magnetic induction (magnetic field)
L = electrode gap
v = flow velocity
Q =volumeflow
A = pipe cross-section
I = current strength
The measuring system consists of a transmitter and a sensor.
Two versions are available:
• Compact version: transmitter and sensor form a single mechanical unit.
• Remote version: transmitter and sensor are installed separately.
Transmitter:
• Promag 50 (user interface with push buttons for operation, two-line display)
• Promag 53 (“Touch Control” without opening the housing, four-line display)
Sensor:
• Promag W, 1” to 78” (DN 25 to 2000)

Power supply failure Lasting minimum 1 power cycle:
• EEPROM or T-DAT™ (Promag 53 only) retain the measuring-system data in the
event of a power supply failure
• S-DAT™ = exchangeable data storage chip which stores the data of the sensor:
nominal diameter, serial number, calibration factor, zero point, etc.
Endress+Hauser optionally supplies reinforced connecting cables with an additional
metal braid. We recommend such cables for the following cases:
• Underground laid cables
• Danger of rodent attack
• Device used with NEMA 6P (IP 68) ingress protection
Operation in areas of severe electrical interference:
The measuring device complies with the general safety requirements in accordance
with EN 61010, the EMC requirements of EN 61326, and NAMUR recommendation
NE 21.
Caution:
Grounding is by means of the ground terminals provided for that purpose inside the
connection housing. Keep the stripped and twisted lengths of cable shield to the
terminals as short as possible.

Potential equalization Standard case
Perfect measurement is only ensured when the medium and the sensor have the
same electrical potential. Most Promag sensors have a standard installed reference
electrode which guarantees the required potential matching. This usually means that
additional potential matching measures are unnecessary.
NOTE: For installation in metal pipes, it is advisable to connect the ground terminal
of the transmitter housing to the piping.
Caution:
For sensors without reference electrodes or without metal process terminals, carry
out potential matching as per the instructions for special cases described below.
These special measures are particularly important when standard grounding
practice cannot be ensured or extremely strong matching currents are expected.

Promag 50/53 W
Endress+Hauser 11
Metallic, ungrounded pipes
In order to avoid errors in measurement, use grounding cables to connect each
sensor flange to its corresponding pipe flange and ground the flanges. Connect the
transmitter or sensor connection housing, as applicable, to ground by means of the
grounding terminal provided for that purpose.
Note:
The grounding cable for flange-to-flange connections can be ordered separately as
an accessory from Endress+Hauser.
•≤12”; the grounding cable is in direct connection with the conductive flange
coating and is secured by the flange screws.
•≥14”, the grounding cable connects directly to the metal transport bracket.
Plastic pipes and lined pipes
Normally, potential is matched using the reference electrodes in the measuring tube.
However, in exceptional cases it is possible that, due to the grounding plan of a
system, large matching currents flow over the reference electrodes. This can lead to
destruction of the sensor, e.g. through electrochemical decomposition of the elec-
trodes. In such cases, e.g. for fiberglass or PVC piping, it is recommended that you
use additional ground disks for potential matching.
When using ground disks, not the following points:
• Ground disks (1” to 12”) can be ordered from Endress+Hauser as an accessory
• Ground disks (including seals) increase the installation length. Refer to the
disk dimensions on page 22.
Caution:
Risk of damage by electrochemical corrosion. Note the electrochemical insulation
rating if the grounding rings and measuring electrodes are made of different materi-
als.
Observe the plant internal grounding guidelines.

Pipes with cathodic protection
If the medium cannot be grounded for process-related reasons, the measuring
device must be installed in such a way as to be potential-free:
• When installing the measuring device, make sure that there is an electrical
connection between the two piping runs, 9 AWG copper wire (6 mm2).
• Make sure that the installation materials do not establish a conductive connection
to the measuring device and that the installation materials withstand the
tightening torques applied when the threaded fasteners are tightened.
• Also comply with the regulations applicable to potential-free installation.

Operating conditions
Installation instructions Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following locations:
• Highest point in the run. Risk of air accumulating
• Directly upstream from an open pipe outlet in a down pipe
Installation of pumps
Do not install the sensor on the inlet side of a pump. This precaution is to avoid low
pressure and the consequent risk of damage to the lining of the measuring tube.
It might be necessary to install pulse dampers in systems incorporating reciprocat-
ing, diaphragm or peristaltic pumps. The sensor is shock and vibration resistant for
acceleration up to 2 g in accordance with IEC 68-2-6.
Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty
Pipe Detection (EPD) function offers additional protection by detecting empty or
partially filled pipes.
Caution:
To avoid the risk of solids accumulating, do not install the sensor at the lowest point
in the drain. It is advisable to install a cleaning valve.

Vertical pipes
Install a siphon (b) or a vent valve (a) downstream of the sensor in vertical pipes
longer than 15 feet (5 meters). This precaution is to avoid low pressure and the
consequent risk of damage to the lining of the measuring tube. These measures also
prevent the system losing prime, which could cause air inclusions.
a = vent valve, b = siphon
Horizontal orientation:
The measuring electrode-plane should be horizontal. This prevents brief insulation
of the two electrodes by entrained air bubbles.
Caution:
Empty Pipe Detection functions correctly only when the measuring device is installed
horizontally and the transmitter housing is facing upward. Otherwise, there is no
guarantee that Empty Pipe Detection will respond if the measuring tube is only
partially filled or empty.
1 = EPD electrode (Empty Pipe Detection)
2 = Measuring electrodes (signal detection)
3 = Reference electrode (potential equalization)
Orientation
An optimum orientation helps avoid gas and air accumulations and deposits in the
measuring tube. Promag, nevertheless, supplies a range of options and accessories
for correct measuring of problematic mediums:
• Electrode Cleaning Circuitry (ECC) to remove electrically conductive deposits in
the measuring tube, e.g. in accretive mediums
• Empty Pipe Detection (EPD) for recognition of partially filled measuring tubes, or
for degassing mediums or for applications with fluctuating process pressure.
Vertical orientation:
This orientation is ideal for self-emptying piping systems and for use in conjunction
with Empty Pipe Detection.

Vibrations
Secure the piping and the sensor if vibration is severe.
Caution:
It is advisable to install the sensor and transmitter separately if vibration is exces-
sively severe. The sensor is shock and vibration resistant for acceleration up to 2 g
in accordance with IEC 68-2-6.
Foundations, supports
If the nominal diameter is 14” or larger, mount the sensor on a foundation of ad-
equate loadbearing strength.
Caution:
Do not allow the sensor casing to take the weight of the sensor. This would buckle
the casing and damage the internal magnetic coils.
Inlet and outlet runs If possible, install the sensor well clear of fittings such as valves, T-pieces, elbows,
etc. Compliance with the following requirements for the inlet and outlet runs is
necessary in order to ensure measuring accuracy:
• Inlet run ≥5 x pipe diameter
• Outlet run ≥2 x pipe diameter
Adapters With the help of the appropriate adapters (reducers and expanders) the sensor can
be mounted in a pipeline of a larger diameter. For slowly flowing fluids, the resulting
higher velocity increases the measuring accuracy.

Length of connecting cable Permissible cable length Lmax depends on the conductivity of the medium. A
minimum conductivity of 20 µS/cm is required for measuring demineralized water.
Gray shaded area = permissible range for medium conductivity
Lmax = length of connecting cable in feet (m)
Medium conductivity in µ S/cm
In order to ensure measuring accuracy, comply with the following instructions when
installing the remote version:
• Secure the cable run or route the cable in a conduit. Movement of the cable
can falsify the measuring signal, particularly if the conductivity of the medium
is low.
• Route the cable well clear of electrical machines and switching elements.
• Ensure ground equalization between the sensor and transmitter, if necessary.
Environment
Ambient temperature Standard: -5° to +140°F (-20° to +60°C) for sensor and transmitter
Optional: -40° to +140°F (-40° to +60°C)
Note the following points:
• Install the device at a shady location. Avoid direct sunlight, particularly in
warm climatic regions.
• If both medium and ambient temperatures are high, specify the remote
transmitter (refer to the “Medium temperature” ranges).
• At ambient temperatures below -5°F (-20°C), the readability of the display may
be impaired.
15° to + 120°F (-10° to +50°C), 70°F (20°C) is the preferable storage temperature.
• The measuring device must be protected against direct sunlight during storage
in order to avoid unacceptably high surface temperatures.
• Choose a storage location where moisture does not collect in the measuring
device. This helps prevent mold, fungus and bacteria from damaging the liner.
• Do not remove the protective plates or caps on the process connections until the
device is ready to install.
• Standard: NEMA 4X (IP 67) for transmitter and sensor
• Optional: NEMA 6P (IP 68) for Promag W sensor, remote version

Process conditions
Medium temperature range The permissible medium temperature depends on the measuring tube liner:
• Polyurethane, -5° to +125°F (-20° to +50°C) for 1” to 78” sensors
• Hard rubber, 32° to +180°F (0° to +80°C) for 3” to 78” sensors
Conductivity Minimum conductivity:
≥5µS/cm →for fluids generally
≥20µS/cm →for demineralized water
Note that in the case of the remote version, the minimum conductivity is also influ-
enced by the length of the connecting cable. Refer to “Length of connecting cable”.

Pressure loss No pressure loss if the sensor is installed in a pipe of the same nominal diameter.
Pressure losses occur in configurations incorporating adapters (reducers, expand-
ers). Contact your Endress+Hauser representative or Endress+Hauser for informa-
tion.
Flow limit As a rule, the pipeline diameter determines the sensor diameter. With a known
flowrate and the help of the Endress+Hauser Flow Applicator, the best size can be
selected. Generally, a velocity range of 6 to 10 ft/sec should be selected.
A necessary increase in velocity can be achieved through a reduction of the sensor
diameter. The higher installation expense is normally balanced by the lower sensor
cost.
The flow velocity should also be determined by the fluid’s physical properties:
• v < 6 ft/sec, for abrasive mediums such as potter’s clay, lime milk, ore slurry, etc.
• v > 6 ft/sec, for fluids causing build-up such as wastewater sludge, etc.
