The discharge measurement is performed by using the well-established tracer-dilution method. The system can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available or unknown. It is used salt (NaCl) as tracer material.
After insertion of a known amount of tracer material two conductivity probes automatically determine the discharge. This way high plausibility and accurate results can be guaranteed. New TQ-COMMANDER V3 software is available!
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 passes. Equally the TQ-tracer works very well in shallow rivers where most other instruments fail to get reliable results or cannot be used any more at all.
The TQ is used particularly in hydrometry as well as by consulting engineers, civil engineers, and hydropower plant operators monitoring the discharge, for control measurements or for project evaluations.
Implementation
The tracer dilution method can be applied for discharge measurement in all waters in which a thorough mixing of the tracer takes place. High turbulences, alternating cross sections and stones promote the mixing process and therefore are helpful. For particularly turbulent waters and very high flow velocities there is a TQ-version available where the sensitive probes are protected with a robust reinforcement. The user-friendly software TQ-Commander leads comfortably through the measurement and provides a full measuring report after the measurement.
