Echo Sounder on Ships Diagram, Principle, working

2019-9-14 · To overcome this problem some of echo sounding machines work on phasing technique. Phasing:-In phasing the speed of the stylus motor remains constant. Instead of changing the speed of the stylus, the transmission point is advanced. If the first range is 0 to 50 M the second range will be 50 to 100 M (instead of 0 to 100 M).

If the measured time is one second and it is known that the speed of acoustic waves is 1500 m/s, the depth is obviously (1500 x 1)/2 metres = 750 m.
