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 -
Why does the flowmeter reading increase when the control valve is partially closed or flow is red...
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 -
How to ensure the measurement accuracy of a clamp-on ultrasonic flowmeter?
First, select an appropriate model based on measurement requirements (e.g., accuracy, pipe diameter, fluid type). Install the device strictly in accordance with the straight pipe section requirements to ensure the correct installation position. Use special coupling agent to ensure tight contact b...Read more -
What are the requirements for the installation location of a clamp-on ultrasonic flowmeter?
The installation location must have sufficiently long straight pipe sections upstream and downstream. Generally, the length of the upstream straight pipe section should be greater than 10 times the pipe diameter, and the downstream section greater than 5 times the pipe diameter. This ensures stab...Read more -

Factors Affecting the Measurement Accuracy of Small-Bore Ultrasonic Flowmeters
Small-bore ultrasonic flowmeters (typically for pipes 6–50 mm in diameter) rely on precise sound wave transmission and signal processing to calculate flow rates, but their accuracy is easily influenced by external conditions, fluid properties, and installation practices....Read more -
Advantages of Small-Bore Ultrasonic Flowmeters: Precision and Versatility for Compact Fluid Systems
Small-bore ultrasonic flowmeters—designed for pipes typically ranging from 6 mm to 50 mm in diameter—have emerged as a game-changing solution for flow measurement in compact, high-precision applications. Unlike traditional mechanical flowmeters (e.g., turbine or p...Read more
