Clamp-On Flow Meter Ultrasonic Meters have been on the market for a long time and provide a convenient method for measuring flow without interrupting the process. In addition to advantages such as no pressure loss, non-destructiveness, and easy maintenance, clamp-on Flow Meters are highly adaptable and low-cost, so they are often used as a flexible flow measurement method.
In field operations, where clamp-on Flow Meters are installed, there are many pipe and medium parameters that are uncertain factors, causing great uncertainty, even the operator cannot find out.
The first point to reduce the uncertainty of clamp-on Flow Meters is to understand the impact of incorrect pipe and medium parameter settings. These parameter settings are often overlooked in work using clamp-on technology. The following are Clamp On Flow Meter Ultrasonic Application Notes
1. Pipeline conditions: To ensure measurement accuracy, the installation point of the clamp-on ultrasonic flowmeter should meet the full pipe condition, that is, the fluid at the measurement point must fill the pipe section. At the same time, avoid installing it in a location where the inner wall of the pipe is severely scaled or there are bubbles, sediments, etc. that affect the measurement.
2. Fluid characteristics: Although the clamp-on ultrasonic flowmeter can measure a variety of fluids, there are certain restrictions on the temperature range of the fluid. Generally, ultrasonic flowmeters in my country are only suitable for fluid measurements below 200°C. In addition, for fluids with strong corrosive, radioactive, flammable, and explosive characteristics, flowmeters with corresponding protective measures must be selected.
3. Installation location: When installing, try to stay away from pump outlets, half-open valves, and other locations where turbulence may occur to ensure the stability of fluid flow. At the same time, avoid installing the sensor in a location where the inner wall of the pipe is severely scaled or susceptible to external interference (such as inverters, radio stations, etc.).
4. Calibration and maintenance: Regular calibration and maintenance of the clamp-on ultrasonic flowmeter is an important measure to ensure its measurement accuracy. Calibration can be done by actual measurement of the portable ultrasonic flowmeter to verify the measurement accuracy of the installation point. Maintenance includes cleaning the probe surface, checking cable connections, etc.
Clamp-on ultrasonic flowmeter plays an important role in modern industrial flow measurement with its advantages of non-contact measurement, easy installation, and wide application range. By deeply understanding its working principle, structural composition, measurement process, and application precautions, we can better utilize this technology to provide accurate and reliable flow data support for industrial production. With the continuous advancement of technology and the continuous expansion of application fields, clamp-on ultrasonic flowmeters will surely play a more important role in the future.
