Function and system design
Measuring principle 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 ampli-
fier. 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 = volume flow
A = pipe cross-section
I = current strength
Measuring system 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:
• DN 2…100

Optionally, Endress+Hauser also supplies reinforced connecting cables with an additional, metal strenghtening
braid. We recommend such cables for the following cases:
• Cables laid underground
• Danger of rodent attack
• Device used with ingress protection IP 68
Operation in zones of severe electrical interference:
The measuring device complies with the general safety requirements in accordance with EN 61010,
the EMC requirements of EN 61326/A1, and NAMUR recommendation NE 21.
Caution!
Grounding is by means of the ground terminals provided for the purpose inside the connection housing.
Keep the stripped and twisted lengths of cable shield to the terminals as short as possible.

Power supply failure Lasting min. 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.)
Potential equalisation Perfect measurement is only ensured when the medium and the sensor have the same electrical potential.
Metal process connections
Potential matching usually takes place over the metallic process connection in contact with medium process
connections which are directly mounted on the measuring transmitter. This usually means that additional
potential matching measures are unnecessary.
Plastic process connections
For plastic process connections, potential matching must be ensured between sensor and medium using addi-
tional ground rings. If these ground rings are missing, this can influence accuracy or destroy the measuring
transmitter through the electrochemical decomposition of electrodes.
A0002651
1 Allen screw (process connection)
2 O-ring seals
3 Plastic washer (spacer) or ground ring
4Sensor
When using ground rings, note the following points:
• Depending on the option ordered, plastic washers may be installed at the process connections instead of
ground rings. These plastic washers serve only as spacers and have no potential equalization function. In
addition, they provide a sealing function at the interface between the sensor and process connection. For this
reason, with process connections without ground rings, these plastic washers/seals must not be removed,
or must always be installed.
• Ground rings can be ordered separately from Endress+Hauser as an accessory.
Also make sure that the ground rings are compatible with the electrode material. Otherwise the danger
exists that the electrodes could be destroyed by electrochemical corrosion. You can find material data on
Page 38 ff.
• Ground rings, incl. seals, are mounted inside the process connection.
This has no influence on the installation length. You can find the dimensions of ground rings on Page 33.
