For very heavy sensors
If the nominal diameter DN ≥ 350 (14 in), mount the sensor on a foundation of adequate load-
bearing strength.
Do not support the weight of the sensor on the metal casing as this could damage the metal casing
and the internal magnetic coils.

Orientation
The direction of the arrow on the sensor nameplate helps you to install the sensor according to the
flow direction (direction of medium flow through the piping).
An optimum orientation position helps avoid gas and air accumulations and deposits in the
measuring tube.
The measuring device also offers the empty pipe detection function to detect partially filled
measuring pipes in the event of outgassing fluids or variable process pressures.
Vertical
This is the optimum orientation for self-emptying piping systems and for use in conjunction with
empty pipe detection.
A0015591
Horizontal
The measuring electrode plane must be horizontal. This prevents brief insulation of the two
measuring electrodes by entrained air bubbles.
With horizontal orientation, empty pipe detection only works if the transmitter housing is
pointing upwards as otherwise there is no guarantee that the empty pipe detection function
will actually respond to a partially filled or empty measuring tube.
