Piping Considerations:
A certain length of straight upstream and downstream piping is necessary to optimize the accuracy of any differential pressure device.
Upstream: The following tabulation provides the minimum straight upstream lengths (expressed as multiples of pipe ID) required for 0.0% and 0.5% additional potential affect in base flow accuracy.
Reduer 2D to D
Expander 05D to D over a length of D to 2D
Full bore ball or gate valve fully open
Two or more 90° bends
over a length of 1.5D to 3D
Upstream feature
Single 90°bend
Additonal Uncertainty Length
0.00% 0.50% 0.00% 0.50% 0.00% 0.50% 0.00% 0.50% 0.00% 0.50% 28D 14D 36D 18D 14D 7D 30D 15D 20D 10D
Downstream: For zero additional uncertainty due to downstream piping, ensure that there are no fittings for 7D downstream of the Venturi or 3.5D for 0.50% additional uncertainty.
