Stationary source emissions. Manual and automatic determination of velocity and volume flow rate in ducts - Manual reference method shop-only

Stationary source emissions. Manual and automatic determination of velocity and volume flow rate in ducts - Manual reference method shop-only1 Scope EN ISO 16911 1 specifies a method for periodic determination of the axial velocity and volume flow rate of gas within emissions ducts and stacks. It is applicable for use in circular or rectangular ducts with measurement locations meeting the requirements of EN 15259. Minimum and maximum duct sizes are driven by practical considerations of the measurement devices described within EN ISO 16911 1. EN ISO 16911 1 requires all flow measurements to
