Sound velocity profilerAs a key equipment for ocean exploration and underwater engineering, it provides basic data for sonar systems, underwater navigation, and ocean research by measuring the sound velocity distribution of seawater at different depths.
Sound velocity profilerIts advantages:
High precision sound velocity measurement
Core function: The sound velocity profiler directly measures the propagation time of sound waves in seawater, combined with environmental parameters such as pressure and temperature, to generate high-precision sound velocity profiles (usually with an accuracy of ± 0.1 m/s).
Technical advantages: Adopting ring ringing method (pulse cycle method) or time leap technology to reduce dependence on time measurement accuracy and ensure data reliability.
Application value: Provide key parameters for sonar equipment such as Doppler current profiler and side scan sonar, optimize their performance, and improve the accuracy of underwater target detection and positioning.
Multi parameter synchronous acquisition
Environmental monitoring: Equipped with pressure and temperature sensors, it can synchronously measure seawater depth, temperature, and sound velocity, and generate three-dimensional profile data.
Data integration: Supports integration with CTD (Temperature, Salinity, Depth) and other devices to provide more comprehensive marine environmental parameters and assist in analyzing environmental factors such as salinity and temperature gradients that affect sound velocity changes.
Flexible deployment and operation
Direct reading and self-contained options: Direct reading supports real-time data transmission and is suitable for dynamic monitoring; Self contained for long-term deployment, storing data and exporting it for analysis, suitable for unmanned environments.
Portability and adaptability: Some models (such as AML-3) are designed to be compact and support handheld or shipborne deployment, suitable for diverse scenarios from shallow to deep sea.
Convenient data sharing and processing
Wireless transmission: Supports Bluetooth or WiFi connections, allowing real-time data transmission to computers or mobile devices, reducing manual intervention.
Software support: Professional software (such as Ocean software) can be used to generate visual profiles, and data export to industry standard formats (such as NetCDF, CSV) is supported for subsequent analysis.
Widely applicable scenarios
Marine science: used for research on marine acoustic environment, seabed topography mapping, and exploration of marine resources.
Underwater engineering: providing sound velocity reference for navigation of underwater robots (ROV/AUV) and installation of underwater structures.
Military field: Support anti submarine operations, underwater target detection, and sonar equipment calibration.
Research education: used by universities and research institutions for teaching and research in oceanography and hydroacoustics.
