ATV underwater ultrasonic acoustic tomography section flowmeter Guangdong pilot completed debugging
Product Description
The installation of an ATV acoustic tomography section flowmeter at a hydrological station located in the Hanjiang River waters of Guangdong Province has been completed. In December 2020, after three days of intense construction, the established tasks were completed from site selection, foundation construction, equipment installation to commissioning.
This product utilizes the comprehensive sound velocity difference between the forward and reverse flow sections of underwater ultrasonic waves to calculate the average flow velocity of the section. Then, by combining the measured water level elevation with the base elevation to calculate the water passage area, the real-time flow rate of the section can be accurately obtained.
The data refresh cycle is 5 seconds. The data upload cycle is usually set at once every 25 seconds.
The master and slave machines are installed on the left and right banks of the river respectively, and real-time data exchange is set up through the high-speed broadband data link of the machine. Utilizing dual-mode high-precision synchronous timing of Beidou and GPS satellites to ensure synchronized recognition of dual machine voiceprints. The river width of nearly 800 meters allows the installation spacing of transducers to be as long as 1200 meters. The new high-sensitivity low-frequency matrix sonar transducer easily modulates the audio signal and delivers it to the opposite bank.
Unique voiceprint recognition verification can accurately distinguish audio from background noise.
Both the master and slave machines adopt independent solar power supply systems, without the need for additional wiring.
