1. An electrochemical process for generating a controlled amount of a reagent electrochemically which comprises providing an electrode in electrical contact with a solution of an electrochemically inert salt, wherein the solution comprises a thin layer thereof of thickness less than 1 mm, creating an electric potential at the electrode for a sufficient time to generate by electrochemical process between the electrode and a component of the solution a controlled amount of the reagent in a localized region of the thin layer adjacent the electrode, and monitoring the presence and amount of the reagent in the localized region, said reagent being generated at known time in a flowing solution and being monitored on arrival at a downstream detector to provide a measure of the rate of flow of the solution.
