ISO International Standard

This International Standard describes the operating principles and the most important performance characteristics

of automated flow-measuring systems for determining the volume flowrate in the ducts of stationary sources.

Procedures to determine the performance characteristics of automated volume flow-measuring systems are also

contained in this International Standard.

The performance characteristics are general and not limited to specific measurement principles or instrument

systems.

NOTE Commercial systems which use the operating principles described and meet the requirements of this International

Standard are readily available.
