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

Two or four transducers are installed on the river banks (half on each bank), and the device measured the return time of the ultrasonic waves between the transducers from one bank to the other. The mean flow velocity is calculated from the time difference between the go and back way
 
 

CONDITIONS OF USE

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