Measurement of water flow in closed conduits — Tracer methods — Part 1: General

Mesure de débit de l'eau dans les conduites fermées — Méthodes par traceurs — Partie 1: Généralités

Abstract / scope

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. Covers choice of method, choice of tracer, choice of measuring length and adequate mixing distance, and possible errors.
