ISO 7194:2008 is an {International Standard https://www.iso.org/es/contents/data/standard/05/06/50627.html?browse=tc} focusing on velocity-area methods for measuring fluid flow in closed conduits, specifically when dealing with swirling or asymmetric flow in circular ducts. It details the measurement techniques, necessary precautions, and corrections required when using current-meters or Pitot static tubes in such conditions. The standard provides guidance on instruments for measuring local velocity, as defined in {ISO 3354 https://www.iso.org/standard/50627.html} and {ISO 3966 https://www.iso.org/standard/50627.html}
