Numerous external factors can affect the meter's successful operation. To ensure that your
system works correctly, consider the factors covered in this section when designing your
installation.
1.4.1
Boundary effect
Boundary effect refers to the distortion in the wave forms in the process fluid that are
caused by reflections from the pipe wall. If the pipe wall is within the meter's effective
measurement region, the boundary effect produces measurement inaccuracy.
