Introduction Measurement Principle The measurement principle is based on the tracer dilution method with instantaneous feed. A known amount of tracer material is added to the water in a rapid pulse. The tracer is taken downstream, mixes with the water and forms an elongated cloud. At a certain point downstream the measuring devices record the tracer concentration with which the discharge can be calculated. No further information about the cross section profile of the body of water is needed for this calculation. Application The tracer dilution method is applicable for discharge measurements in...

Salt (NaCI), which can be easily injected and dissolved in water, is used as tracer material. 1) The probe to be used is a conductivity probe. It has an internal temperature compensation and is linearised according to the norm EN27888 for natural water. For use in very turbulent rivers and at high flow velocities the probes of the TQ-S can be equipped with a protective and heavy armour. A main advantage of using fluorescence tracers is the small minimum concentration required for detection. Therefore, only a very small amount of tracer material needs to be added to the water and yet measureing of...
