Measurement of water flow in closed conduits — Tracer methods — Part 6: Transit time method using non-radioactive tracers

Tracer methods apply to flow measurement in conduits into which a solution can be injected and those cases where effective mixing of this solution with the water flowing in the conduit can be achieved, this last condition being fundamental. Describes the transit time method using non-radioactive tracers for the measurement of water flow rate in closed conduits.
