3.4 Installation condtitions
INFORMATION!
For accurate volumetric flow measurement the measuring device needs a completely filled pipe and a fully developed flow profile.
Please observe the instructions regarding inlet and outlet pipe runs as well as the installation position.
In the event of 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
•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.
•Do not lay signal cables directly next to cables for the power supply.
