Vertical pipes
Install a siphon (2) or a vent valve (1) downstream of the sensor in vertical pipes
longer than 15 feet (5 meters). This precaution is to avoid low pressure and the
consequent risk of damage to the lining of the measuring tube. These measures
also prevent the system losing prime, which could cause air inclusions.

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.
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.

Vertical orientation:
This orientation is ideal for self-emptying piping systems and for use in conjunction
with Empty Pipe Detection.
