Measurement of fluid flow in closed conduits. Velocity-area methods of flow measurement in swirling or asymmetric flow conditions in circular ducts by means of current-meters or Pitot statics tubes subscription-only Conformity assessors of a service1 Scope This International Standard specifies velocity area methods for measuring flow in swirling or asymmetric flow conditions in circular ducts by means of current meters or Pitot static tubes. It specifies the measurements required, the precautions to be taken, the corrections to apply, and describes the additional uncertainties which are introduced when a measurement in asymmetric or swirling flow has to be made. Only flows with a negligible
