All pipe types and sizes
Select a pipe location that provides a minimum straight length of pipe of at least 10
times the pipe’s nominal pipe size and mark a point that is at least 5 times the pipe
diameter downstream from the nearest pipe fitting. See section 1.5 for the minimum
straight pipe length requirements.
If the fluid to be measured contains more than 10% particles, the meter should be
operated using the Doppler measurement method. For Doppler operation, the
transducers will be mounted directly opposite each other as shown below.
If the fluid contains little or no particles (up to 10% maximum), operate the meter using
the Transit Time method to obtain the best accuracy. Select a mounting mode that allows
the greatest sound travel distance while permitting good signal strength. Basic pipe
material and size guidelines are shown below.
