3.4 Installation conditions
The meter MUST be protected from strong sunlight.
A sunshade is available from the manufacturer as an option.
INFORMATION!
For accurate volumetric flow measurement the measuring device needs a completely filled pipe
and a fully developed flow profile.
CAUTION!
Any vibration will distort the measuring result. That is why any vibrations in the pipeline must be
prevented through suitable measures.
CAUTION!
Procedures to carry out before installing the device:
•
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.
•
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 centering rings.
•
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.
•
At product temperatures or ambient temperatures >+65
°
C / +149
°
F, a connection cable and
cable glands with a minimum service temperature of +80
°
C / +176
°
F must be used.
INFORMATION!
If there is a risk of water hammers in steam networks, appropriate condensate separators must
be installed. Suitable measures must be taken to avoid water cavitation if it is a possible risk.
