Easyflow
Très compact et léger, l’appareil EasyFlow est l’instrument idéal pour la mesure de débit de torrents ou de cours d’eau sauvages. Il est destiné aux professionnels qui réalisent des jaugeages occasionnellement et qui n’ont pas besoin d’enregistrer plusieurs sites. Il permet de réaliser en quelques minutes la mesure d’un débit selon la méthode par dilution de traceur.
Très ergonomique et parfaitement étanche, EasyFlow est muni d’une sonde de conductivité avec un câble de 10m. Il est livré dans une sacoche nylon à bandoulière avec 3 doses d’étalonnage, le logiciel EasyViewer, un aide-mémoire et un câble USB de communication. Il est donc très facile à transporter.
The EasyViewer software enables data to be transferred to a PC, the gauging curve to be viewed and, if necessary, the flow rate calculation to be corrected. It is very useful, even necessary, to check the quality of the gauging by viewing the curve.
Main software functions:
- Loading measurement data from EasyFlow
- Display of the gauging curve and possibility of graphically correcting the flow calculation
- Ajout d’informations sur le jaugeage, comme la hauteur limnimétrique
- Software in three languages: German, English or French
