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 measuring flow?
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 -
Why does the flowmeter reading increase when the control valve is partially closed or flow is reduced?
This is usually because the sensor is installed too close to the downstream of the control valve. When the valve is partially closed, the flowmeter actually measures the increased flow velocity caused by the reduced diameter of the valve. The solution is to move the sensor away from the control v...Read more -
Why does the flowmeter show low or no flow velocity when the sensor is functioning normally?
Possible causes and solutions include: Paint or rust on the pipe exterior not fully removed: Re-clean the pipe surface before reinstalling the sensor. Uneven pipe surface or installation over a weld seam: Polish the pipe surface or install the sensor away from weld seams. Poor pipe roundness, ro...Read more -
How to address inaccurate readings or large errors of a clamp-on ultrasonic flowmeter?
There are multiple potential causes: If sensors are mounted on the top or bottom of a horizontal pipe (leading to signal interference from sediments), reposition them to the sides of the pipe. If installed on a downward-flowing pipe with insufficient fluid filling, relocate the meter to a fully ...Read more -
Why does the flowmeter display unstable and fluctuating readings, and how to resolve this issue?
This may be caused by excessive vibration of the pipe where the ultrasonic flow sensor is installed, or the presence of flow-altering devices (e.g., the flowmeter is installed downstream of control valves, pumps, or orifices). The solution is to reinstall the flow sensor away from vibration sourc...Read more
