2.3 Considerations
2.3.1 Limitations
Structural
Structural limitations are printed on the sensor tag. Exceeding structural limitations may cause
sensor failure.
Functional
The most accurate and repeatable flow measurement occurs in the following conditions:
The structural limit differential pressure, as printed on the sensor tag, is not exceeded.
The instrument is not used for two-phase flow or for steam service below saturation
temperature.
Install the flowmeter in the correct location within the piping branch to prevent
measurement inaccuracies caused by flow disturbances.
The flowmeter can be installed with a maximum misalignment of 3 degrees (see Figure
2-1). Misalignment beyond 3 degrees will cause flow measurement errors.
Figure 2-1. Permissible Misalignment
2.3.2 Environmental
Mount the flowmeter in a location with minimal ambient temperature changes. Appendix A:
Specifications and Reference Data lists the temperature operating limits. Mount to avoid
vibration, mechanical shock, and external contact with corrosive materials.
Access requirements
Consider the need to access the flowmeter when choosing an installation location and
orientation.
