3.1.
Mechanical Installation
In accordance with this manual the user should select the installation position which fits the application best. To
ensure the highest degree of accuracy and repeatability, care should be taken to affix the TRICOR products in a
stable process site and minimize the amount of vibration in the installation environment.
3.1.1.
Installation Guidelines
Coriolis Mass Flow Meters measure the flow of a gas by vibrating the medium perpendicular to the flow direction
and measuring the effect of the inertial force of the medium. Consequently, for best performance the meter must
be decoupled from external vibrations and the medium must be homogenous.
External vibration:
In case of (possible) external vibrations connect the meter mechanically rigidly to a non-vibrating point or
– if
this is not possible
– connect it by means of vibration dampers.
The TCM 0450/TCMH 0450 has to be mounted using the mounting holes, and must not be fixed directly to the
external tubing.
Piston pumps and other pumps producing a strongly pulsating flow should be decoupled hydraulically via longer
pipes, flexible tubes or other measures.
Inhomogeneous media:
In case the medium contains liquid droplets or solid particles make sure that those droplets or particles do not
accumulate inside the meter. For this, the meter has to be mounted with tubes coming from the bottom side.
3.1.2.
Horizontal Installation
The horizontal installation is the recommended installation.
The
TCM 0450/TCMH 0450
has to be mounted using the four mounting holes.
Fix the meter to a solid, non-
vibrating surface as close to the meter as possible.
If no non-vibrating surface is available, vibration dampers might be recommended.
