3.6.1 General installation notes

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.
The following procedures have to be carried out before installing the device:
• Remove all transportation safety devices and protective coverings from 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 housing of
the measuring sensor.
• On metering points with varying thermal loads, the flowmeters 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 metering point.

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