The Role of Open Channel Flow Meters in Environmental Monitoring and Water Resource Management
Water, as a vital resource for all life on Earth, requires precise monitoring and scientific management to maintain ecological balance and meet human needs. In this context, open channel flow meters have emerged as indispensable tools, bridging the gap between raw water ...Read more -
In what harsh environments can radar flow meters be used? How are their waterproof and corrosion-resistant performances?
Thanks to the advantage of non-contact measurement, radar flow meters are suitable for various harsh environments: they can be used in rivers with sediment and suspended solids, industrial wastewater discharge outlets, and can also operate stably for a long time in outdoor environments such as hi...Read more -
What factors affect the measurement accuracy of radar flow meters? What accuracy can be achieved in practical applications?
The accuracy of radar flow meters is mainly affected by the following factors: First, installation conditions—the sensor must be perpendicular to the water surface and installed in a straight channel section (no obstacles at least 5 times the channel width upstream and 2 times the channel width d...Read more -
Applications of Radar Flow Meters
Radar flow meters, leveraging their core advantages such as non-contact measurement, strong anti-interference capability, and adaptability to harsh environments, have become key equipment for flow monitoring in free-surface flow scenarios including open channels, rivers, and sewage outfalls. The...Read more -

Open Channel Flowmeters: Precision Measurement for Unpressurized Fluid Systems
In industrial, municipal, and environmental engineering, measuring the flow of unpressurized fluids—such as wastewater in treatment plants, stormwater in drainage channels, or irrigation water in agricultural ditches—requires specialized tools. Unlike closed-pipe systems...Read more -
Can an ultrasonic flowmeter measure accurately when the medium flow velocity in the pipeline is very low (e.g., < 0.1 m/s) or very high (e.g., > 10 m/s)?
Extreme flow velocities pose challenges to the lower and upper measurement limits of ultrasonic flowmeters, resulting in significant differences in accuracy performance: Low Flow Velocity (< 0.1 m/s) At this stage, the medium flow is close to laminar flow, with poor uniformity of velocity dist...Read more -
Doppler Flowmeters vs. Transit-Time Models: Key Differences for Wastewater & Slurry Applications
In industries like municipal wastewater treatment, mining, and chemical processing, measuring the flow of complex fluids—whether sewage laced with debris or abrasive mineral slurries—demands tools tailored to these challenging conditions. Among ultrasonic flowmeters, two...Read more -
Will the sensor of a clamp-on flowmeter be corroded when used for long-term measurement of pipelines carrying corrosive media (such as acid and alkali solutions)? Is the sensor lifespan related to ...
The clamp-on sensor itself does not come into direct contact with the medium. Its housing is usually made of 316L stainless steel, PTFE (polytetrafluoroethylene), or ABS engineering plastic, so it will generally not be corroded by the corrosive medium inside the pipeline. However, the corrosion a...Read more -
Does the thickness and material of the insulation layer affect the measurement accuracy when a clamp-on ultrasonic flowmeter is installed on an insulated pipeline? Are special treatments required?
It has an indirect impact, but the core issues are not the insulation layer itself, but the air gaps between the insulation layer and the outer wall of the pipeline, as well as the coupling effect. If the insulation layer (e.g., rock wool, polyurethane) fits tightly against the outer wall of the...Read more -
Will the accuracy difference between single-path and multi-path ultrasonic flowmeters widen with flow rate changes when measuring large-diameter pipelines (e.g., DN1000 and above)?
Yes. Single-path ultrasonic flowmeters typically measure the flow velocity at the center of the pipeline and then convert it to the average flow velocity across the pipeline cross-section using an “average velocity coefficient.” This coefficient is based on the assumption of a “...Read more
