How should an ultrasonic flowmeter choose the measurement point?

Thread Content

　　As a highly precise instrument, a flow meter requires strict adherence to its specifications not only during manufacturing and use, but also requires special attention during maintenance in order to prevent it from reaching the end of its useful life prematurely. The installation of ultrasonic flowmeters will be explained in detail below. It is the simplest and most convenient among all types of flowmeter installations. However, to ensure measurement accuracy, the measurement point should be located in a straight section of the pipeline. The following principles should generally be followed: 1. Choose a straight pipe section filled with liquid, such as a vertical section of the pipeline (with the flow direction from bottom to top being preferable), or a horizontal pipe filled with liquid (the lowest point in the entire pipeline being ideal). The pipeline must not be partially empty during installation and measurement. 2. The measurement location should be at a point where there is a straight pipe section of more than 10D upstream of the probe and 5D downstream of it. 3. The measurement point should be placed as far away as possible from devices such as pumps and valves, to avoid interference with the measurements. 4. It is also important to keep the measurement point as far away as possible from high-power radio transmitters and strong magnetic field sources. 5. Consideration should be given to any scaling in the pipeline; it is best to choose a pipe section without scaling for measurements. When scaling is severe, an insert-type probe should be selected. 　　6. The pipe material selected should be uniform and dense, allowing easy propagation of ultrasonic waves. 7. After determining the initial installation position of the pipe segment, use a grinding wheel or steel file to polish the surface of the metal pipe over an area three times the size of the probe’s surface (approximately 100 mm in size), removing rust and paint so that the pipe wall surface becomes smooth and even. Note that the surface should have a uniform finish without any irregularities, and it should maintain the same curvature as the original pipe. Be careful not to polish the installation area into a flat surface; finally, clean it thoroughly with alcohol or gasoline.
