OCEAN MAPPING EQUIPMENT HOME >TECHNOLOGY>OCEAN MAPPING EQUIPMENT

The sound velocity is one of the important hydrological parameters. Measuring accurately the sound velocity is the basis of range surveying precisely by means of any sonar. The depth correction of a single- beam echo sounder, the beam-angle correction of the multi-beam echo sounder and the sound ray curvature correction depend all on the measurement of the sound velocity profiles. HY1200 model sound velocimeter is the equipment through surveying the sound velocity of the sea (river, lake) and the profile of the temperature extensively used in the water depth survey near the ocean, the river and the lake.
