4.6 General information on installation
The following points must be observed during installation:
• The meter tube must always be completely full.
• The flow direction must correspond to the marking, if there is one.
• The maximum torque for all flange connections must be complied with.
• The meters must be installed without mechanical tension (torsion, bending).
• Wafer design flowmeters with coplanar counter flanges may only be installed with suitable
gaskets.
• Only gaskets made from a material which is compatible with the media and its temperature
may be used.
• Gaskets must not extend into the flow area since possible turbulence could affect the
accuracy of the meters.
• The pipelines must not exert any impermissible forces or torques on the meter.
• Do not remove the plugs in the connectors until you are ready to install the electrical cable.
• Make sure the gaskets for the housing cover are seated properly. Carefully gasket the cover.
Tighten the cover fittings.
• Do not expose the transmitter to direct sunlight and provide for appropriate sun protection
where necessary.
• When selecting the installation site, make sure that moisture cannot penetrate the terminal
housing or transmitter compartment.
• Make sure the signal cable connectors are plugged in and tightened properly to ensure IP 67
protection.
