STRAIGHT PIPE LENGTH [FIG. 2]
As a rule, secure the straight pipe length of at least 7D up-
stream and 3D downstream (D: Flowmeter inner diameter).
For actual straight pipe length, see table below.
Pay attention to following items for securing the accuracy.
(1) Use a connecting pipe of an inner diameter same as or
(2) If there is “abrupt expansion of piping diameter” up-
(3) Provide a regulating valve downstream the flowmeter.
