Scope

Main technical content: This document specifies the use of insertion turbine flowmeters as standard instruments for online calibration of gas flowmeters with an inner diameter of ≥300mm in metallurgical dedicated circular closed pipes. It stipulates the calibration items, methods, and technical requirements, and provides a method for evaluating measurement uncertainties. Gas flowmeters used for low-pressure and low-flow applications in other pipes with an inner diameter of ≥300mm can be implemented in accordance with this document.
