1 Mechanical Installation
1.1 General principles
The OPTIMASS mass flow meters provide high accuracy and excellent repeatability. Narrow band pass
digital filtering, and the mathematically modelled internal primary head design with AST (Adaptive Sensor
Technology) for the OPTIMASS sensor family provide exceptional immunity to external vibratory
disturbances from nearby process equipment.
The accuracy of the flow meter is not affected by velocity profile.
The following installation guidelines are practical to implement, particularly if planned before the
OPTIMASS meter is first installed. For further dimensions or connections, please refer to the relevant
section.
For the OPTIMASS, in general, no special mounting requirements are necessary. However, good general
engineering practice for the installation of flow meters should still be observed.
The general guidelines described in this section are valid for the complete OPTIMASS family of mass flow
meters.
•
The mass flow meters do not require any straight inlet or outlet runs.
• Due to the weight of the meters we recommend the use of supports.
• It is permissible to support the body of the meter.
• 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.
This label on the meter shows the flow direction programmed into the converter in function 3.1.4.
As default this is always in the direction of the ‘+’ arrow, i.e. left-to right as the label is viewed.
