Mounting
Grounding
The grounding of the sensor is important both for safety reasons and for the electromagnetic flowmeter to function properly. The grounding screws
of the sensor should be connected to protection conductor potential. For measurement reasons, this should be identical to the medium potential
as far as possible.
For plastic lines or pipelines with insulating lining, the grounding is via a grounding plate or grounding electrode. If the pipe section is not free from
external interference voltages, it is recommended that one grounding plate is fitted in front of the sensor and one is fitted behind the sensor.
Grounding plates are available upon request
see „Grounding plates “, page 57.
Installation
General information
•
The measuring pipe must always be full.
•
The flow direction must match the identification marking
see „Flow direction “, page 17.
•
The maximum torque for all flange screws must be observed. These must be selected according to factors including temperature, pressure,
screw and seal material, and the relevant regulations in each case.
•
Install the devices without any mechanical tension (torsion, bending).
•
Fit flange devices with plane-parallel counterflanges only using the appropriate seals.
•
Use a flange seal made from a material that is compatible with the medium and the medium temperature.
•
Seals may not extend into the flow area, since any turbulence affects the device accuracy.
•
The pipeline must not exert any inadmissible forces or torque on the device.
•
Only remove the sealing plugs in the cable fittings when installing the electrical cables.
•
Install remote mount transmitters at a location that is largely free of vibration.
•
Do not expose the transmitter to direct sunlight; provide sun protection if necessary.

Maintain a minimum clearance of 0.7 m (2.3 ft) between the devic-
es to prevent any mutually interference.
