3.1.3 Straight, Unimpeded Inlet And Outlet Runs
D = Meter Size (Nominal diameter in inches)
With a  ow straightener, the inlet pipe length may be reduced by 50%. For example, with a
control valve upstream, the inlet length is 25D instead of 50D. The minimum inlet pipe length
including the  ow straightener must always be at least 12D.
3.1.4 Minimizing Pipe Vibration
Pipe vibration caused, for example, by the action of pumps, valves, etc. will distort  ow
measurements, particularly at low  ow velocities. To minimize the effects of vibration,
support the pipeline on both sides of the meter in a direction perpendicular to both the
pipeline and the shedder bar axis.
