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 V2 software is available! More details
