Stationary source emissions. Manual and automatic determination of velocity and volume flow rate in ducts - Automated measuring systems Ingestion-build-46800 What is PD 6550-4 –1 Scope EN ISO 16911 2 describes specific requirements for automated measuring system (AMS) flow monitoring. It is partly derived from EN 14181 which is the general document on the quality assurance of AMSs and is applicable in conjunction with that document. EN ISO 16911 2 specifies conditions and criteria for the choice, mounting, commissioning and calibration of AMSs used for determining the volume flow rate from a source in ducted gaseous streams.
