Model 803 for ROV
“Designed specifically for use on ROVs and other underwater vehicles, the Model 803 provides real-time relative water velocity information for pilots.
It may be fitted to ROVs to provide actual through the water speeds, or fitted to Tether Management Systems to give the measurement of local flow conditions. Measurements are updated every second and the ROVLog™ software provides a graphic and data display and enables data to be logged to disk.”
