G821 Dual-mode Liquid Ultrasonic Flow

During measurement, the dual-mode liquid ultrasonic flowmeter adopts a measurement method that automatically switches between Time-of-Flight (TOF) measurement and Doppler measurement. It uses TOF measurement in scenarios where the medium is relatively uniform, and Doppler measurement when the medium contains particles or bubbles. The installation method adopts a clamp-on non-contact measurement approach, enabling the measurement of various water media (drinking water, raw water, sewage), oils (lubricating oil, diesel oil, fuel oil, crude oil), as well as highly corrosive, toxic, and harmful chemical substances. It is not affected by process pressure or medium conductivity, and can cover a maximum measured pipe diameter of DN5000, making it an economical and efficient flow measurement solution.
