SalinoMADD
EasyFlow EasyFlow is a simple-to-use gauging device for users who
occasionally effectuate flow measurements and don’t want to do
a too big investment.
It permits to realize in few minutes the measurement of the flow
of a stream thanks to the tracer ddilution
d
ilution method method. method
The tracing
The conductivity probe is placed into the watercourse. Upstream, at a sufficient distance to assure a good mix
of the tracer in the water, a known quantity of salt is injected, beforehand diluted in stream water into a
container (about 10 grams per l/s of estimated flow). During the passing of the salt cloud, it records the salinity
values of the water. When this cloud has passed, the flow of the watercourse is calculated and displayed in
litres by seconds.
Software EasyViewer
The software EasyViewer for PC is furnished with the EasyFlow EasyFlow. EasyFlow
It permits the downloading of measurement
data, then the visualisation and the processing of the gauging curve. Additional information as the limnimetric
height can be also saved with data in file.
To verify the efficiency of the gauging, the recorded data in the EasyFlow EasyFlow can be uploaded into a PC. Then it is
possible to visualise these data graphically. Some tools are available to recalculate the flow measurement by
changing parameters or to print the result and the curve as presented below.
