YUNYI Doppler open channel flowmeter is a non-contact flow monitoring instrument based on the Doppler effect principle. It transmits ultrasonic waves of a specific frequency toward the water surface and receives echo signals reflected back by suspended solids, bubbles, or fine particles in the water. By calculating the frequency shift (Doppler shift) between the transmitted and received waves, it precisely determines the water flow velocity. Simultaneously, it utilizes the ultrasonic wave velocity to measure water level in real time. Equipped with intelligent algorithms and pre-programmed channel cross-section shapes (such as Parshall flumes, rectangular, and trapezoidal channels), the meter automatically calculates and outputs instantaneous flow rate and cumulative flow. This provides a maintenance-free, reliable solution for flow monitoring in complex water bodies like sewage and stormwater. Product Advantages The core value of the Doppler open channel flowmeter lies in its resistance to contamination and simple installation, perfectly resolving measurement challenges faced by traditional methods in harsh water conditions. 1. Non-contact measurement, impervious to contamination and corrosion: The sensor is suspended above the water surface, avoiding contact with the water body. This completely eliminates issues such as corrosion, scaling, debris entanglement, and sensor wear, resulting in extended service life and minimal maintenance. 2. Adaptable to Extremely Complex Water Conditions: Measurement relies on reflections from suspended solids and bubbles in the water, making it particularly suitable for measuring sewage,
