Simple and fast calibration for increased accuracy at the measuring point.
The usage of two sensors guarantees a simple plausibility check of the
measurement results.
Input of salt
TQ-S with heavy reinforcement and cable reel for easier handling in the field.
The length of the river section has to be carefully considered.
TQ-Tracer
The discharge measurement is performed by using the proven tracer-dilution method. It can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available.
As a tracer material salt is used. After insertion of a known amount of tracer material two conductivity probes are determining the discharge.
- Simple, mobile discharge measurement
- Reliable results even without knowledge and independent of the cross-section profile
- Suitable for fast-flowing, turbulent waters or where access is limited
- Environmentally friendly, harmless for water
- Discharge values immediately available
- Easy transmission of measurement data from the sensor to receiving device via Bluetooth
- Convenient receiving of data on laptop
- Real-time visualisation of measurement data
- User-friendly guidance through the measurement by the included software TQ-Commander
- Simultaneous measurement with up to four probes
- Tracer material: salt (NaCl)
- Probe type: conductivity probe
- Compact and convenient: complete equipment securely packed in two cases
