In case of horizontally laid pipes avoid pipe top and pipe bottom as mounting
place (risk of soiling or air bubbles resulting in measurement failure).
NIVUS recommends a mounting position of -45° ... +45° to the horizontal..

6.3.2 Choosing Sensor Position and Required Distances
Clear and defined hydraulic conditions are indispensable prerequisites for accu-
rate measurements. This is why one has to be especially attentive to the re-
quired hydraulic calming sections.
-
The pipe must be fully filled
-
Falls, steps, fittings, profile change of channels or lateral supplies right in
front of or behind the measurement point have to be avoided!
-
The length of the approach channel must be min. 5x nominal diameter, the
length of the discharge channel must be min. 2x nominal diameter. Longer
sections may be required however in case of disturbed hydraulic conditions
and distorted flow profiles resulting from these conditions
-
Avoid measuring in bevelled pipelines or in pump intake lines.
