The English name for "测深仪" is "echo sounder." Echo sounders are widely used in the field of oceanography and marine exploration to measure the depth of the ocean floor and gather valuable information about the underwater environment. These instruments play a crucial role in revealing the silent journey through the mysteries of the sea.

Echo sounders work on the principle of sound waves and echoes. They emit a sound signal in the form of a pulse, which travels through the water until it reaches the seabed. When the sound wave encounters an object or the bottom of the ocean, it reflects back towards the surface. The echo sounder then receives these returning echoes and measures the time it takes for the sound to travel back. By calculating the time and knowing the speed of sound in water, the instrument can accurately determine the depth of the seafloor.
