Description
Descripción
The discharge measurement is performed by using the proven tracer-dilution method and is especially suitable for high volumes of water. It can be deployed in turbulent rivers, creeks or waters for which data regarding the cross-section profile are not available. As a tracer a fluorescent material is used. After insertion of a known amount of tracer material two optical fluorescence probes are determining the discharge.
FEATURES AND ADVANTAGES
- 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
- Applied especially with water amounts of several m³/s
- Environmentally friendly, harmless for water
- Discharge values immediately available
- Easy transmission of measurement data form 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: fluorescence (fluorescein or similar)
- Probe type: optical fluorescence probe
- Compact and convenient: complete equipment securely packed in two cases
