Today, the HJ-UT Series Ultrasonic Time-of-Flight (ToF) Open Channel Flow Meters, developed by Shenzhen Huaju Scientific Instrument Co., Ltd., are driving rapid advancements in the industry with their exceptional performance and innovative technologies. Leveraging decades of expertise in ultrasonic technology from our core team and a fully self-developed ToF platform, we have pioneered two groundbreaking technologies: ASE (Acoustic Signal Enhancement™) and HPDM (High Precision Discharge Measurement™). These innovations ensure the platform’s superior performance, enabling the HJ-UT Series to achieve industry-leading accuracy and versatility in flow measurement.

Product Highlights

• Fully Self-Developed: Built on decades of ultrasonic technology expertise, the ToF platform features in-house development from hardware and software to algorithms.

• ASE Technology: Acoustic Signal Enhancement™ improves signal-to-noise ratio through dynamic emission frequency, low-damping transducer structure design, and high-gain, low-noise receiving circuits. This enhances ToF measurement precision and stability, ensuring reliable time-difference accuracy.

• HPDM Technology: High Precision Discharge Measurement™ dynamically adjusts velocity sampling rates across flow layers and employs advanced cross-sectional partitioning for precise volumetric flow calculations.

• Radar Fusion Technology: Integrates Huaju’s cutting-edge radar expertise for high-accuracy, stable water level measurement.

• Versatile Configurations: Available in open-frame and enclosed modular designs to suit channels of varying sizes and shapes.
