TRACER SYSTEM TQ-F: Efficient Tracking Solution

TRACER SYSTEM TQ-F

MOBILE DISCHARGE MEASUREMENT SYSTEM FOR TURBULENT RIVERS WITH UNKNOWN CROSS-SECTION PROFILE – FLUORESCENCE TRACER

The discharge measurement is performed by using the well-established tracer-dilution method which is especially suitable for high volumes of water. 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 as a fluorescent material as a tracer. After the insertion of a known amount of tracer material two optical fluorescence probes automatically determine the discharge. This way high plausibility and accurate results can be guaranteed. New TQ-COMMANDER V2 software is available! More details

Description

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 anymore 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.
