Part A Installation and Start-up
1. Installation in the pipeline
1.1 General principles
The MFM 4085 K/F CORIMASS mass flow meter provides high accuracy and excellent
repeatability. Narrow band pass digital filtering, and the mathematically modelled internal
primary head design provides exceptional immunity to external vibratory disturbances from
nearby process equipment. The accuracy of the flow meter is not affected by velocity profile.
The straight single tube means there is a very low risk of cavitation, and no air can be trapped
inside the meter. No back pressure is required at the outlet of the meter. As with all Coriolis
mass flow meters, the CORIMASS is an active device with its own energy source. A good
installation is essential for the high measurement accuracy.
The following installation guidelines are practical to implement, particularly if planned before the
CORIMASS is first installed. For further dimensions or connections, please refer to Section D,
Technical Data.
1.2 Installation Guidelines
1.2.1 Mounting location
For the G+ no special mounting requirements are necessary. However, good general
engineering practices for the installation of flow meters should still be observed.

The meter can be installed horizontally, in an upward sloping pipeline or vertically. For best
results, a vertical installation with flow in an upward direction is recommended.
