Damage to the device
Damage to the device due to improper assembly.
• The use of graphite with the flange or process
connection gaskets is prohibited. This is because, in
some instances, an electrically conductive coating
may form on the inside of the meter tube.
• Vacuum shocks in the piping should be avoided to
prevent damage to the liners. Vacuum shocks can
destroy the device.
NOTICE
The flowmeter sensor can be installed at any location in the
piping while taking the installation conditions into account.
1 Remove protective plates, if present, to the right and left
of the meter tube. To prevent possible leakage, make
sure that the liner on the flange is not cut or damaged.
2 Position the flowmeter sensor plane parallel and
centered between the piping.
3 Use the appropriate screws for the holes in
accordance with Torque information on page
136.
4 Slightly grease the threaded nuts.
5 Tighten the nuts in a crosswise manner as shown
in the figure. Observe the tightening torques in
accordance with Torque information on page
time to the maximum torque. Do not exceed the
max. torque.
