The Hamburg Port Authority (HPA) ordered a second discharge monitoring station. The monitoring station is based on two Horizontal ADCPs mounted on pole in the middle of the River Elbe. The two H-ADCP are mounted back to back looking toward the shore. Aqua Vision will handle the complete system integration including the data GPRS communication. Our ViSea HCT will combine the two individual data streams to one discharge value. J. Bornhöft Industriegeräte GmbH has delivered the two H-ADCPs.
