Measurement of gas flow in conduits — Tracer methods — Part 4: Transit time method using radioactive tracers

Mesurage de débits de gaz dans les conduites — Méthodes par traceurs — Partie 4: Méthode fondée sur le mesurage du temps de transit, utilisant des traceurs radioactifs

Abstract / scope

Applies to flow measurement in conduits into which a tracer can be injected in such a way that effective mixing in single phase with the gas flowing in the pipe can be achieved. The fluid in the conduit can be a mixture of several gases provided the thermodynamic state and conditions of flow of this mixture are well defined. This part specifies the transit time method using radioactive tracers for the measurement of gas flow in conduits.
