TQ-Tracer
Mobile discharge measurement with
salt or fluorescent tracers
Properties and benefits
» Simple and mobile discharge measurement
» Works also with complex cross section geometries
» For sediment-rich and turbulent waters
» Discharge measurement immediately available
» Plausibility control of the measurement due to the
simultaneously use of up to 4 probes
» Bluetooth transmission to a notebook, PDA or
smartphone
» Low power consumption
» System with conductivity or fluorescence
sensors (uranin / rhodamine)
» Easy system change (conductivity /fluorescence)
by a probe replacement
