5 ...Installation
Electrode axis Minimum spacing of the devices
The flowmeter sensor should be mounted in the piping in
such a manner that the electrode axis is oriented as
horizontally as possible.
permissible.
• In order to prevent the devices from interfering with each
other, a minimum distance as presented in Minimum
spacing of the devices must be maintained between the
devices.
• The sensor must not be operated in the vicinity of
powerful electromagnetic fields, e.g., motors, pumps,
transformers, etc. A minimum spacing of approx. 3.28 ft
(1 m) must be maintained.
• For installation on or to steel parts (e.g. steel brackets), a
minimum spacing of 3.94 in (100 mm) must be
maintained.
• These values have been calculated on the basis of IEC 801
2 or IEC TC77B

Mounting position
Note
For a horizontal mounting position, make sure that the sensor
is installed to be self-draining.
Electrode axis
Vertical installation for measuring abrasive materials,
preferably with flow in upward direction.
For a horizontal installation, the meter tube must always be
completely filled with the measuring medium. Provide for a
slight incline of the connection for degassing.
