1 Electrode axis 
 
Figure 12:  Orientation of the electrode axis 
 
The flowmeter sensor should be mounted in the piping in such a 
manner that the electrode axis is oriented as horizontally as 
possible. 
A maximum deviation of 45° from the horizontal position is 
permissible. 
 
 
Mounting position 
 
 
Figure 13:  Mounting position 
 
A Vertical installation for measuring abrasive materials, 
preferably with flow in upward direction. 
B 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. 
 
 
 
Note 
For hygienic applications, the vertical mounting position is 
preferred. 
For a horizontal mounting position, make sure that the sensor is 
installed to be self-draining.

Figure 14:  Minimum spacing 
 
 
•  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. 1 m (3.28 ft) must be 
maintained. 
•  For installation on or to steel parts (e.g. steel brackets), a 
minimum spacing of 100 mm (3.94 in
) must be maintained.  
These values have been calculated on the basis of IEC 801-2 
or IEC TC77B
