HY1202 Surface Velocity Profiler
  • Accurate & reliable sound velocity measurement adopting “Time of Flight” Technology;

  • Corrosion and pressure resistant compact 316 stainless steel housing;

  • Mechanical design for easy cleaning, optimal flow and flexible integration;

  • Direct path ultrasonic echosounding with 2MHz transducer element

The HY1202 is a real-time surface velocity profiler for sound measurement in ocean,river and lake within 50 meters depth rating. It is applied to fixed-mount installation on surface ships, submarines, AUVs, ROVs and other self-propelled platforms. The HY1202 SVP adopts “Time of Flight” technology and improves the accuracy to 0.05 m/s, which reaches to world-leading level. It is connected to MBE or other instruments via cables, which achieves power supply and RS232 data communication.
