FLUORESCENCE TRACER TQ-F
DISCHARGE MEASUREMENT VIA TRACER DILUTION METHOD FOR SEWAGE – FLUORESCENCE
The discharge measurement is performed by using the well-established tracer-dilution method and is especially suitable for big volumes of water. It is used a fluorescent material as tracer. When using the tracer in sewage water most often a continuous insertion of a known amount of tracer is done. Two optical fluorescence probes automatically determine the discharge. This way high plausibility and accurate results can be guaranteed.

- Simultaneous measurement with up to four probes
- Tracer material: optical fluorescence (fluorescein or similar)
- Probe type: fluorescence probe
- Compact and convenient: complete equipment securely packed in two cases
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 stages promote the mixing process and therefore are positive. As a tracer a fluorescence material has to be used, because salt cannot be used due to the changing conductivity in sewage water (see TQ-S). The insertion of the tracer material usually takes place automatically via a proportioning pump. The user-friendly software TQ-Commander leads comfortably through the measurement and provides a full measuring report at the end.
- Rivers & Streams: Ideal for fast-flowing, turbulent waters, creeks, and mountain streams with complex or unknown cross-sections.
- Natural & Technical Canals: Applicable in both natural waterways and engineered canals.
- Sewage & Wastewater: Suitable for treatment plants, canals, and combined/separate sewage systems.
- Hydrometry & Water Management: Used by water/wastewater associations and civil engineers for monitoring, control, extraneous water measurement, and model calibration.
- Hydropower: Supports discharge monitoring at hydropower plants.
- Project Evaluations: Used in field studies and evaluations for hydrometry projects.
