Installing the meter tube

Notice – potential damage to device!
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
(PTFE). Vacuum shocks can destroy the device.
The meter tube 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 meter tube coplanar and centered between the piping.
3. Install gaskets between the surfaces; see chapter .
IMPORTANT (NOTE)
For achieve the best results, ensure the gaskets fit concentrically with the meter tube
4. Use the appropriate screws for the holes in accordance with chapter .
5. Slightly grease the threaded nuts.
6. Tighten the nuts in a crosswise manner as shown in the figure. Observe the tightening
torques in accordance with chapter !
First tighten the nuts to approx. 50 % of the maximum torque, then to 80 %, and finally a
third time to the maximum torque. Do not exceed the max. torque.
