Product Features
—
01
Dual-Mode Measurement Monitoring Measurement: High-penetration point measurement with multi-point, wide-range, and high-precision velocity detection. Scanning Measurement: Millisecond-level continuous rapid measurement to capture flow velocity fluctuations.
02
Supports Ultra-Low Velocity Mode: Capable of measuring flow velocities as low as 0.005 m/s.
03
High Measurement Accuracy: The product utilizes dual high-frequency, high-sensitivity transducers combined with low-phase-noise transmission and reception circuits, achieving high-precision flow velocity detection. It also includes a built-in high-precision temperature sensor to monitor water temperature in real time and adjust acoustic parameters, ensuring accuracy across various scenarios.
04
Compact and Durable Design: Small form factor with a streamlined body design, reducing the risk of debris accumulation and minimizing impact on water flow. The fully sealed housing is made of corrosion-resistant, high-strength plastic, ensuring reliability and durability.
