    摘要： A method of determining the concentration of a chemical agent in a solution is provided the method comprising the steps of: providing a pressurized solution of said chemical agent upstream of a dosing unit in a line; changing the opening condition of said dosing unit at a determinable time to to provide a dosing of said solution or a change in the dosing of said solution; determining the time, t p , at which the pressure wave in said line resulting from the pressure drop upon changing the opening condition of said dosing unit is detected at a known distance, d, from said dosing unit; determining the velocity of wave propagation from said time interval t p - to and said known distance, d; and deriving the concentration of said chemical agent from said velocity of wave propagation. The invention also pertains to a system for determining the concentration of a chemical agent in a solution, operating according to the same method.
