A Portable ultrasonic sounder is a device that uses ultrasonic technology to measure the water depth and is widely applied in fields such as ocean surveys, river and lake measurements, and underwater engineering. It determines the water depth by emitting ultrasonic pulses and receiving their reflected echoes.
The device emits ultrasonic pulses underwater. When the sound waves encounter the water bottom or other obstacles, reflections are generated, and the reflected waves are received by the device. By calculating the time difference between the emission and reception of the sound waves and multiplying it by the propagation speed of sound waves in water (about 1500 meters per second), the water depth can be obtained.
In addition to water depth measurement, the Portable ultrasonic sounder also has multiple functions. It can judge the type of bottom sediment through the characteristics of the echo and conduct bottom sediment analysis. At the same time, the device can store the measurement data for subsequent analysis and display the water depth and bottom contour in real - time through the display screen. Some high - end devices are also integrated with GPS to provide the location information of the measurement points and realize navigation and positioning functions.
A Portable ultrasonic sounder usually consists of the following core components: a transducer, which is used to transmit and receive ultrasonic waves; a control unit, which is responsible for processing signals, calculating the water depth, and displaying the results; a power supply, which provides the electricity required by the device, and common power sources are batteries or external power supplies; a data interface, which is used for data transmission and connection to external devices; and a display unit, which displays the measurement data in real - time. Some devices are equipped with touchscreens for more convenient operation.
