Difficult Installation Locations For Liquid Measurement; Installation In The Vicinity Of Pumps - ABB CoriolisMaster serie Inbetriebnahmeanleitung

4.6.5 Difficult installation locations for liquid
measurement
The accumulation of air or gas bubbles in the meter tube will
lead to increased inaccuracies.
Avoid the following installation locations in case of liquid
measurement:
Fig. 10: Difficult installation locations
— "A": Installing the flowmeter sensor at the highest point of a
pipeline leads to increased inaccuracies due to the
accumulation of air or gas bubbles in the meter tube.
— "B": Installing the flowmeter sensor in a drop line means
that there is no guarantee that the meter tube will be
completely full while measurements are being taken and
leads to increased inaccuracies.

Installation in the vicinity of pumps

Strong vibrations in the pipeline must be damped using
flexible damping devices.
The damping devices must be installed beyond the supported
flowmeter section and outside of the section between the
shut-off devices.
Do not connect flexible damping devices directly to the
flowmeter sensor.
