STHY1200 Series Velocity of Sound Section Device

Using the tach-ring method for velocity of sound measurement, the HY1200 series velocity of sound section device can offer velocity of sound section data quickly for the fathometer, sonar, sound label underwater etc, which help them proofread effectively measuring error so as to increase accuracy of the water depth measurement . In this article, we expatiate its principle of velocity of sound measurement and introduce the constitution, function and operation of the velocity of sound measuring device . Moreover, we have studied and analyzed the data obtained from experiment and application, and point out some usage announcements.
