Installation conditions
The following points must be observed during installation:
• Install the sensor in rigid pipelines in order to support the weight of the meter.
• The device must be installed without mechanical tension (torsion, bending).
• Install flange devices with plane parallel counter-flanges and only use appropriate gaskets.
• Use proper gaskets made from a material that is compatible with the measuring medium and
measuring medium temperature.
• Gaskets must not extend into the flow area, since possible turbulence could influence the
accuracy of the device.
• The piping may not exert any inadmissible forces or torques on the device.
• Make sure that the temperature limits are not scaled up during operation of the device.
• Vacuum shocks in the piping should be avoided to prevent damage to the liners (PTFE liner).
Vacuum shocks can destroy the device.
• Do not remove the blind plugs in the cable glands until you are ready to install the electrical
cable
• If earthing rings are used, use standard flange gaskets on both sides of the ring.
