2.2.3 Orientation
An optimum orientation helps avoid gas and air accumulations and buildup in the measuring
tube. The measuring device, nevertheless, supplies a range of functions and tools to measure
problematic fluids correctly:
• Electrode cleaning circuitry (ECC) to prevent electrically conductive deposits in the measuring
tube, e.g. for fluids causing buildup
• Empty pipe detection (EPD) for detecting partially filled measuring tubes, e.g. in the case of
degassing fluids or varying process pressures
• Exchangeable measuring electrodes for abrasive fluids (only Promag W)
Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the two
electrodes by entrained air bubbles.
"
Caution!
In the case of horizontal orientation, empty pipe detection only works correctly if the transmitter
housing is facing upwards. Otherwise there is no guarantee that empty pipe detection will
respond if the measuring tube is only partially filled or empty.

This orientation is optimum for self-emptying piping
systems and when using empty pipe detection (EPD)
or open electrode detection (OED).
