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.
FIELDS OF APPLICATION
The TQ-Tracer system is especially suitable for sewage applications (purification plant, sewage canals, separate or combined flow systems, aso.) for calibration measurements, measuring and detecting extraneous water, for calibration of calculation models or for control measurements. The measuring device is used particularly by water and wastewater associations, sewage plants, canal management, engineering offices, civil engineers or industry.
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.
