Product Description
The SV20 series surface sound velocity meter adopts the most advanced "time leap" technology for sound velocity measurement, and combines advanced digital signal processing technology to achieve a world leading measurement accuracy of 0.03m/s for sound velocity.
The speed of sound in water, as an important parameter for all sonar devices, has been widely used in various military and civilian fields such as ocean surveys, underwater engineering, underwater surveying, and underwater navigation and positioning. With the upgrading of various sonar devices, higher and higher requirements have been put forward for the accuracy of sound velocity measurement. Therefore, the traditional sound velocity measurement accuracy based on the "ring sounding method" sound velocity meter can no longer meet the demand for high-precision sound velocity measurement. Therefore, combined with the most advanced sound velocity measurement methods internationally, a new sound velocity measurement method has been developedSV20Series high-precision surface acoustic velocity meter.
SV20The series of surface sound velocity meters adopts the most advanced "time leap" technology for sound velocity measurement, and combines advanced digital signal processing technology to achieve a measurement accuracy of 0 for sound velocity The world's advanced level of 0.3 m/s.
