Mounting The Meter Tube - ABB VA Master FAM540 Inbetriebnahmeanleitung

3.2.2

Mounting the meter tube

The meter can be installed at any location in a pipeline under consideration of the installation
conditions.
Warning - Potential damage to device!
Use of graphite with the flange or process connection gaskets is prohibited. In some
instances, an electrically conductive coating may form on the inside of the measuring tube.
For meters with PTFE liners (FAM545), vacuum shocks in the pipelines should be avoided to
prevent damage to the liners. Vacuum shocks can destroy the meter.
1. Remove protective plates, if present, above and below the meter tube. Make sure that small
internal parts such as floats or the conical meter pipe do not fall out and become damaged.
2. Position the meter tube coplanar and centered between the pipes.
3. Install gaskets between the surfaces.
Important
For best results, make sure the flowmeter primary gaskets fit concentrically with the measuring
tube.
4. Use the appropriate screws for the holes.
5. Slightly grease the threaded nuts.
6. Tighten the nuts in a crosswise manner as shown in the figure.
Important
Torques for screws depend on temperature, pressure, screw and gasket materials. The
relevant applicable regulations must be taken into consideration.
