ESMDPL1000 Portable Doppler ultrasonic flow meter for Open channels, urban sewage pipes, river flow monitoring

The Doppler ultrasonic flowmeter is a non-contact flow measurement instrument developed based on the Doppler effect, specifically designed for turbid fluids containing suspended particles and bubbles, and is widely used in municipal, industrial, and water conservancy fields. The instrument features an external clamp-on installation, requiring no pipe cutting, making installation and maintenance convenient, with no pressure loss and no interference with the flow field, effectively protecting the integrity of the pipeline.

Its core working principle involves the sensor emitting ultrasonic waves at a fixed frequency. By using the Doppler shift generated by the reflected waves from scatterers in the fluid, along with the cross-sectional area of the pipe, the instrument accurately calculates instantaneous and cumulative flow. It has built-in temperature compensation and noise-resistant design, providing strong measurement stability.

The product has a wide flow velocity range (0.05–10 m/s), a range ratio of up to 1:200, and can accommodate large flow fluctuations. It has a comprehensive accuracy of ±1%–±2% FS, protection ratings of IP65–IP68, and can withstand complex environments such as humidity and dust. It is suitable for scenarios like wastewater treatment, mine slurry, pulp, and river channels, but not ideal for measuring pure water, making it an ideal device for monitoring turbid fluid flow.
