Doppler Flowmeters vs. Transit-Time Models: Key Differences for Wastewater & Slurry Applicat...
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 pipeli...
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 cl...
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 ...
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 -
Doppler Flowmeters: How They Measure Particle-Laden Fluids with Non-Invasive Precision
In industrial fluid measurement, particle-laden fluids—such as wastewater, mining slurries, or crude oil with sediment—pose unique challenges. Traditional flowmeters, like turbine or positive displacement models, often struggle with these fluids: internal components can ...Read more -
Key Specifications to Consider When Investing in an Ultrasonic Flowmeter
Investing in an ultrasonic flowmeter is a critical decision for industries ranging from water treatment to oil and gas, as it directly impacts operational efficiency, measurement accuracy, and long-term cost-effectiveness. Unlike traditional flowmeters, ultrasonic models...Read more -
How Ultrasonic Flowmeters Enable Non-Invasive, High-Precision Fluid Measurement
In industrial fluid management, the need for measurement tools that combine accuracy with minimal process disruption has made ultrasonic flowmeters a game-changer. Unlike traditional flow measurement devices—such as turbine meters that require internal components t...Read more -
Characteristics of Mechanical Water Meters
A mechanical water meter is a traditional water flow metering device, widely used in daily life and industrial production due to its simple structure and low cost. Its specific characteristics are as follows: Advantages Simple Structure: It mainly consists of mechanical components such as impel...Read more -
How often should coupling agent be reapplied to the transducers?
Record the signal strength during the initial installation of the transmitter and transducers. When the signal strength drops by 50%, although the meter may still operate normally, the signal strength has decreased significantly compared to the initial installation. At this point, it is recommend...Read more -
What to do if a clamp-on ultrasonic flowmeter cannot be used due to strong on-site interference?
Strong on-site interference may stem from large fluctuations in the power supply, nearby frequency converters or strong magnetic fields, or incorrect grounding. The solutions include providing a stable power supply for the flowmeter, installing the flowmeter away from frequency converters and str...Read more -
How to resolve low signal issues with a clamp-on ultrasonic flowmeter?
Low signal may result from excessively large pipe diameter, severe pipe scaling, or incorrect installation method. For large pipe diameters or severe scaling, it is recommended to use insertion probes or adopt the “Z-method” installation. Additionally, ensure the pipe surface at the p...Read more -
How to troubleshoot a clamp-on ultrasonic flowmeter that is functioning normally but not measurin...
Potential causes and solutions are as follows: Changed measured medium: Adjust the measurement mode. Medium vaporization due to excessive temperature: Cool down the medium. Medium temperature exceeding the sensor’s temperature limit: Cool down the medium. Aged or depleted coupling agent un...Read more
