Orientation
An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring tube.
Promag, nevertheless, supplies a range of functions and accessories for correct measuring of problematic fluids:
• Electrode Cleaning Circuit (ECC) for applications with fluids producing build-up, e.g. electrically conductive
deposits
→
"Description of Device Functions" manual.
• Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes, e.g. in the case of
degassing fluids.
Vertical orientation
A vertical orientation is ideal in the following cases:
• For self-emptying piping systems and when using empty pipe detection.
• For sludge containing sand or stones and where the solids cause sedimentation.

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 with the measuring device installed horizontally only when the
transmitter housing is facing upward (see diagram). Otherwise there is no guarantee that Empty Pipe Detection
will respond if the measuring tube is only partially filled or empty.
