3.8 Installation
3.8.1 General installation notes
The following procedures have to be carried out before installing the device:
•
Ensure that the gaskets have the same diameter as the pipelines.
•
Note the correct flow direction for the device. This is indicated by an arrow on the neck of the
flow sensor.
•
On measuring points with varying thermal loads, the devices have to be mounted with stress
bolts (DIN 2510).
•
Stress bolts or bolts and nuts are not included in the scope of delivery.
•
Ensure that the measuring flange is concentrically fitted.
•
Note the exact installation length of the measuring device when preparing the measuring
point.
CAUTION!
Installation, assembly, start-up and maintenance may only be performed by appropriately
trained personnel. The regional occupational health and safety directives must always be
observed.

CAUTION!
The internal diameter of the pipelines, the flow sensor and the gaskets must match. The gaskets
may not protrude into the flow.
