ACOUSTIC DOPPLER CURRENT PROFILER
This device carried out discharge
measurements in measuring vertical velocity profiles in using the
It measures also both its own speed
and direction relating to the river bottom in using the same
Relating to the river depth, the
profiler divides the vertical profiles in a number of elementary cells,
and measures the mean velocity and direction of each cell. From these data
it calculates the total discharge.
CONDITIONS OF USE
The profiler should offers both
installation possibilities on a boat or as a sentinel fixed at the bottom
of the river for continuous discharge measurement.
Frequency range : from 300kHz to
1200 kHz. e.g. 600 kHz for shallow waters (less than 20m).
