Horizontal
• Ideally, the measuring electrode plane should be horizontal. This prevents brief

• 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.
