1.2 Suggestions for installation
To avoid measuring errors due to
air inclusion and vacuum, please
observe the following:
Highest point of pipe run
(Air bubbles collect in measuring
tube - faulty measurements!)
Horizontal pipe run
Install in slightly descending pipe section to
prevent air from collecting, so avoiding faulty
measurements and that meter can drain.
Control and shutoff valves: always install
behind the flowmeter
Pumps
Do not install flowmeter on pump suction side
Open feed or discharge
Install meter in low section of pipe
open discharge
Selecting the installation location
Location and position as required, but
electrode axis (X – – – – X
must be approximately horizontal in a
horizontal pipe run.
Direction of flow The red arrow on the
primary head housing must point in the flow
direction.
On high-temperature pipes and
where process temperatures
exceed 100 °C, provide facilities to
compensate for longitudinal
expansion on heat-up of the pipeline.
Use flexible pipe elements (e.g.
elbows).
Preferred
locations
downpipe
(open discharge)
Avoid draining or partial filling of
the measuring tube. Faulty
measurements.
