“Efficient installation method of clamp-on ultrasonic flowmeter”
Ultrasonic flow meters are a popular choice for measuring flow in various industries due to their non-invasive and precise measurement. Among the different types of ultrasonic flow meters, clamp-on ultrasonic flow meters stand out for their ease of installation and minimal disruption to existing piping systems. In this blog, we will explore effective installation methods for clamp-on ultrasonic flow meters.
1. Planning before installation:
Before the installation process begins, a thorough evaluation of the piping system and flow characteristics is critical. This includes identifying pipe material, diameter and wall thickness, as well as determining the best location for sensor placement. Additionally, it is important to ensure that the pipes are clean and free of any obstructions that could interfere with the ultrasonic measurements.
2. Correct sensor placement:
The accuracy of flow measurement depends heavily on the correct placement of the ultrasonic sensor. The transducer is usually clamped to the outside of the pipe and should be positioned in a way to allow optimal ultrasonic signal transmission. The manufacturer’s sensor placement guidelines must be followed, and the sensor must be securely fastened to the pipe to prevent any movement or sliding.
3. Surface treatment:
To ensure reliable and accurate measurements, the pipe surface to which the sensor is clamped should be properly prepared. This may involve cleaning the surface to remove any dirt, grease, or rust, and roughening the surface to improve adhesion of the sensor coupling material. Proper surface preparation is essential to achieve good acoustic coupling between the sensor and pipe, which is critical for accurate flow measurement.
4. Coupling material application:
Ultrasonic sensors require coupling materials to facilitate the transmission of ultrasonic waves through the pipe wall. A coupling material (usually a gel or paste) should be applied to the sensor before clamping it to the pipe. Care should be taken to ensure that the coupling material is applied evenly and adequately to the transducer to ensure optimal acoustic coupling to the pipe.
5. Calibration and testing:
After the sensor is securely clamped to the pipe and coated with coupling material, the flow meter should be calibrated and tested to verify its accuracy. This may involve conducting baseline flow tests using known flow rates to verify the measurements. Additionally, any necessary adjustments or fine-tuning should be made to the flow meter settings to ensure accurate and reliable performance.
In summary, the installation of a clip-on ultrasonic flow meter requires careful planning, proper sensor placement, surface preparation, application of coupling materials, and thorough calibration and testing. By following these effective installation methods, industries can benefit from the accurate and non-intrusive flow measurement capabilities of clamp-on ultrasonic flow meters.
