The AquaProfiler M-Pro measures the Doppler-shift in up to 128 cells along each of the two ultrasonic beams and then calculates the velocity vector that accounts for the flow. Each vertical is separated into 128 individual measuring cells, each with a minimum size of 1 cm. At the end of each vertical, The user receives a velocity profile that delivers unparalleled transparency of the actual flow behavior within the cross section in high resolution. After a successful connection of HDA-Pro and Sensor via a powerful wireless WIFI connection, the measurement can most efficiently be done with a party of 2. Here, one person makes the actual measurement in the river going from vertical to vertical along the cross section, Whereas the second person operates the HDA- Pro or his notebook standing on the river bank, a bridge, inside a gauging house etc. He can also check the results for plausibility and instruct his partner in case additional measurement are necessary.
