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.
