vibrations
vibrations on the piping, select the installation site so that the vibrations are at
their lowest in a transverse direction to the flowmeter.
CAUTION!
When installing the device in the piping, the following points must be observed:
•
Nominal diameter of connection pipe flange = nominal flange diameter of pipe!
•
Use flanges with smooth holes, e.g. welding neck flanges.
•
Align carefully the holes of the connecting flange and the flowmeter flange.
•
Check the compatibility of the gasket material with the process product.
•
Make sure that the gaskets are arranged concentrically. The flange gaskets must not project
into the pipe cross-section.
into the pipe cross-section.
•
The flanges have to be concentric.
•
There must not be any pipe bends, valves, flaps or other internals in the immediate inlet run.
•
Devices in sandwich version may only be installed using a centering ring.
•
Never install the device directly behind piston compressors or rotary piston meters.
•
