Tracer System TQ-F (Fluorescence Tracer)

The discharge measurement is performed by using the proven tracer-dilution method and is especially suitable for high volumes of water. It can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available. As a tracer a fluorescent material is used. After insertion of a known amount of tracer material two optical fluorescence probes are determining the discharge.

Fields of application

The TQ-Tracer system is especially suitable for fast-flowing, turbulent waters with complex cross sections, for example, mountain streams, small brooks, tributaries or even fish ladders. The measuring device is used particularly in hydrometry as well as by engineering offices, civil engineers or power plant operators, for instance for control measurements or for evaluating projects.

The tracer dilution method can be applied for discharge measurement in all waters in which a thorough mixing of the tracer ensues. High turbulences, alternating cross sections and stones promote the mixing process and therefore, have a positive effect on the measurement. For particularly turbulent waters and very high flow velocities there is a model available with robust reinforcement. The user-friendly software TQ-Commander leads comfortably through the measurement and provides a full measuring report.
