Orientation
An optimum orientation helps avoid gas and air accumulations and deposits in the measuring tube. Promag,
nevertheless, supplies a range of options and accessories for correct measuring of problematic mediums:
• Electrode Cleaning Circuitry (ECC) to remove electrically conductive deposits in the measuring tube, e.g. in
accretive mediums.
• Empty Pipe Detection (EPD) for recognition of partially filled measuring tubes, or for degassing mediums or
for applications with fluctuating process pressure.
Vertical orientation:
This orientation is ideal for self-emptying piping systems and for use in conjunction with Empty Pipe Detection.

Horizontal orientation:
The measuring electrode-plane should be horizontal. This prevents brief insulation of the two electrodes by
entrained air bubbles.
Caution!
Empty Pipe Detection functions correctly only when the measuring device is installed horizontally and the
transmitter housing is facing upward. Otherwise there is no guarantee that Empty Pipe Detection will respond
if the measuring tube is only partially filled or empty.
