Figure 2-8: Installation in bending pipes (90
°
)
INFORMATION!
Recommended installation positions are at a lowered or ascending section of the pipeline
installation. Installation at the highest point will enlarge the risk of flowmeter malfunction,
because of air/gas bubbles.
Vertical installation in combination with an open surcharge has to be avoided.
Vertical installation with a controlled back-pressure is possible.

°

INFORMATION!
Vertical installation on a descending slope in the pipeline is only recommended when the back-
pressure is controlled.
CAUTION!
Avoid draining or partial filling of the flow sensor
