Methods for measurement of fluid flow in closed conduits, using tracers. Measurement of water flow - Constant rate injection method using non-radioactive tracers Ingestion-build-109673 National and local regulations takeWhat is BS 5857 1. 2 Constant rate injection method about? BS 5857 1. 2 is an International Standard that discusses the fluid flow in closed conduits, using tracers. BS 5857 1. 2 specifies the constant rate injection method using non radioactive tracers for the measurement of water flow rate in closed conduits. Flow rate measurement by a constant rate injection method is based on a comparison between the concentration C1 of a tracer, continuously
