ATD Wireless Ultrasonic Doppler Flow Profiler

Measurement Principle:

Ultrasonic waves maintain effective transmission within 200 meters underwater, ensuring the integrity of direct wave propagation. Therefore, an underwater sonar sensor is installed diagonally at 45 degrees on both the left and right banks of the river channel. This setup can detect the direct wave signals affected by upstream and downstream currents, which is commonly referred to as the time-difference flow measurement method. The time difference of the arrival of the direct waves is directly proportional to the velocity of the water layer in the direct sound path of the sensor.

Compared to traditional time difference methods, both left and right banks utilize self-organized wireless data link communication, with dual machines performing time synchronization through satellites, ensuring no interference with navigation in the waterway.

Key Features:

▶ Measurement Parameters: Flow Rate, Flow Volume, Water Level, Cross-sectional Area of Flow, Water Temperature, Conductivity, etc.

The master and slave machines are installed at fixed locations on the left and right banks, respectively.

▶ Utilizes dual-mode BeiDou and GPS timing synchronization;

Master and slave station self-organized network wireless data link

▶ Initial identification and determination time for direct to the wave.

▶ Both master and slave units feature real-time display with acoustic wave reception.

▶ Both the master and slave units come with a complete setup menu and operation buttons.

▶ Master and slave units feature IP65 aluminum shell structure with industrial design.

▶ Integrated with 50 base elevation settings;

▶ Primary Acoustic Components: Ultrasonic transducers are installed at 45° angles to the underwater current direction, on both sides of the riverbanks.

▶ Master and slave machines feature a 7-inch color LCD display, equipped with a built-in 4G all-network component, directly transmitting to the hydraulic platform.

▶ Can measure zero flow, low flow;

▶ Holds: multiple patents and software copyrights;

▶ Selected for the "National Water Conservancy System Bidding Product Procurement Catalog"

Application Scenario:

Hydrology, hydraulic engineering, and environmental protection departments use cross-sectional flow measurement in rivers and streams, suitable for river widths ranging from 20 to 200 meters.
