Easyflow
The EasyFlow gauge is compact and light, and is ideal for measuring flow in torrents of water or wildly flowing streams. It is designed for professionals. A flow can be gauged using the tracer dilution method in a few minutes.
The EasyFlow gauge is very ergonomic and perfectly waterproof, and is supplied with a conductivity probe with 10 metres cable. It is delivred in a shoulder bag and with 3 calibration doses, EasyViewer software, a quick manual and USB communication cable.
The software EasyViewer, delivered with the device, allows the download of the data on the PC, the visualization of the gauging curve and the eventual correction of the flow calculation. Very usefull to verify the quality of the gauging by viewing the curve.
Main functions:
- Download measured data from EasyFlow
- Visualization of the gauging curve and possibility to correct graphically the flow calculation
- Addition of information about the gauging, such as the limnimetric height
- Software in 3 languages: french, german and english
