2. The "interference enemy" of ultrasonic flow meters - common interference source analysis
Ultrasonic flow meters face various interference factors in practical use, mainly divided into two categories: internal interference and external interference. These interferences can affect measurement accuracy, equipment stability, and reliability. Internal interference mainly comes from the components or working characteristics of the flowmeter itself, including the following aspects: scaling on the inner wall of the pipeline. Sediments on the inner wall of the pipeline can change the propagation path of ultrasonic waves, leading to signal attenuation or abnormal reflection, and thus causing measurement errors. For example, in industrial pipelines that operate for a long time, scale or chemical deposits may cover the pipe walls, affecting the penetration of ultrasonic waves. Solution: Regularly use cleaning devices (such as high-pressure water jets or chemical cleaning agents) to remove sediment from the inner wall of the pipeline and restore the conditions for ultrasonic propagation. Solid particles or bubbles impurities (such as sediment, metal particles) or bubbles in liquid media can scatter or absorb ultrasonic signals, causing fluctuations or underestimation of measurement values. For example, in sewage treatment scenarios, suspended solid particles may interfere with the propagation path of ultrasonic waves. Solution: Install a settling device or filter to reduce the solid particle content in the medium. Use gas detectors to monitor bubbles and promptly remove them through exhaust devices. Fluctuations in power supply and unstable power supply voltage can cause abnormal operation of electro
