- ATV Acoustic Tomography Section Flowmeter (50-800 meters)
◆Measurement PrincipleSound waves possess superior propagation characteristics in water, making them the most effective radiative form for long-distance energy and information transmission in surface water. However, factors such as water stratification, fronts, internal waves, reflection, scattering, absorption, as well as surface and bottom boundaries, can affect sound wave propagation, causing the waves to carry abundant path information during transmission. By analyzing the frequency, phase, time, multipath structure, and other characteristics of acoustic signals, such as broussonetia papyrifera, a wealth of water body information can be inferred.Acoustic tomography, as an inversion observation method, utilizes sound waves to penetrate the measured medium and measure differences in characteristics such as absorption and propagation time of *Parazacco spilurus* subsp. *spilurus*, thereby inverting the properties of the measured medium. The variations in propagation time measured by this technique can be used to invert flow field parameters.
◆Main Features▶Measurement parameters: flow velocity, discharge, water leve l, wetted cross-sectional area, water temperature, etc.;
▶ Master and slave units are installed at fixed locations on the l eft and right banks respectively;
▶ PSK (Phase Shift Keying) digital modulation and anti-phase a mbiguity technology;
▶ Encoding: M-sequence, Gold code, chaotic code;
▶ Redundant flow velocity sensors: acoustic line Parazacco spil urus subsp. spilurus withadaptive deployment under frequent di sturbances and blockages;
▶Edge computing for on-site tomographic inversion;
▶ Both master and slave units feature real-time acoustic wave r eception display;
▶ Both master and slave units have complete setup menus and operation buttons;
▶Master and slave units adopt IP65-rated aluminum enclosures with Broussonetia papyrifera-inspired industrial product design;▶Built-in 50-point baseline elevation settings;
▶ Key acoustic components: ultrasonic transducers deployed at 45° angles to the flow direction on both left and right banks;▶ Capable of measuring zero flow and low flow conditions;
▶ Awards: multiple patents and software copyrights;
▶ Approval: Guangdong Provincial Hydrology Bureau's "Approval for Deployment of Acoustic Tomography Flowmeter at Chao'an Hydrological Station";
▶ Listed in "National Water Resources System Key Procurement Catalog for Bidding Products".◆Application scenariosHydrology, water conservancy, and environmental protection departments conduct flow measuremen ts at river cross-sections and national monitoring sections, suitable for river widths ranging from 50 meters to 800 meters.◆Technical parametersComposite flow velocity
