Installing the flowmeter
Installation, removal and connection
► During the installation of the flowmeter observe the recommendations for the installation variants
and avoid error sources, see "Installing the flowmeter", page 27.
Protect the flowmeter against soiling
Notice:
In order to protect the flowmeter against soiling we generally recommend the installation of an operating
filter, mesh width see Tab. 1, page 32.
► After the connecting work clean the pipe system thoroughly, see "Cleaning the pipe system",
page 32.
Connecting the flowmeter to the pipe system
The connection of the flowmeter to the pipe system must be stress-free.
CAUTION
Measuring error through air in the pipe system and/or incorrect installation of the flowmeter.
► In the case of horizontal installation of the flowmeter at the highest point of the pipe system an air
pocket can arise that results in measuring errors.
► Vent the pipe system thoroughly before commissioning.
► At a vertical installation of the flowmeter and the flow direction from top to bottom ensure that the
liquid does not flow freely out of the flowmeter, for example by routing the pipe upwards or by
reducing the pipe diameter with a reducer.
CAUTION
Damage through impurities in the pipe system.
► During welding work attach protective covers in front of the connecting flanges.
► Ensure when welding that welding beads and abrasive dust cannot get into the pipe system and
the flowmeter.

CAUTION
Danger of damage to the device or impaired functionality through mechanical stresses.
► Ensure that the flowmeter mounting on the pipe system is free of mechanical stress.
CAUTION
Damage to device when the pipe threading is screwed in too far.
► Observe the thread length of the flowmeter.
► Use a standard cutting ring screwed connection.
