ACOUSTIC DOPPLER CURRENT PROFILER


GENERAL

This device carried out discharge measurements in measuring vertical velocity profiles in using the
acoustic energy.

It measures also both its own speed and direction relating to the river bottom in using the same
technique as for the flow velocity measurement
 

MEASUREMENT SPECIFICATIONS

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.
As it is fitted with an internal compass, it calculates  also its direction to the north. So it is not necessary for the boat to follow a straight cross section for carrying discharge measurements
This equipment should be used in rivers up to 400 meters wide. Some civil works are generally needed for the transducer installation .
 

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.
This equipment should be used in rivers up to 400 meters wide. Some civil works are generally needed for the transducer installation .

TECHNICAL SPECIFICATIONS

Frequency range : from 300kHz to 1200 kHz. e.g. 600 kHz for shallow waters (less than 20m).
Temperature and salinity compensation
Pitch and roll compensation
Power supply : external battery 12 to 24V
Waterproof battery pack for sentinel using
