Methods for measurement of fluid flow in closed conduits, using tracers. Measurement of gas flow - GeneralWhat is BS 5857 2. 1 Measurement of gas flow about? BS 5857 2. 1 is an International Standard that discusses the gas flow in closed conduits, using tracers. BS 5857 2. 1 applies to flow measurement in conduits into which a tracer is injected in such a way that effective mixing in a single phase with the gas flowing in the pipe is achieved.
