Xylem Instruments Vital Role in Rio De Janeiro Harbor Monitoring
HidroMares has installed its SISMO systems at seven port complexes around Brazil, from ocean terminals in the south to an inland river port in the Amazon basin. At the heart of each system is a SonTek acoustic Doppler current profiler (ADCP), which provides current velocity and direction data throughout the water column, as well as water level. That allows SISMO units to provide current data to pilots at six depths—from the surface to 12 meters, in two-meter increments—as well as highly accurate depth measurements from a vertical acoustic beam and a pressure sensor, all refreshed every five minutes. In Rio de Janeiro’s Sepetiba Bay, HidroMares positioned three bottom-mounted SonTek Argonaut-XR systems in the channel, leading their cables up to surface buoys outfitted with data transmission equipment. HidroMares also positioned an Argonaut-SL side-looking ADCP at the end of the pier to deliver a current profile extending 120 meters from the dock.
