This article is reproduced from: http://www.shllzdh.cn/information/914.html. Keywords of this article: rotameter. Rotameters can also be affected by various factors during use, such as the fluid medium, temperature, pipeline vibrations, and so on. Next, the editor will focus on explaining the effects that measuring dirty fluid media with a flow meter can have. Measuring dirty fluid media with a helical vortex flowmeter can cause measurement errors. As the metering process proceeds, a large amount of dirt and other contaminants accumulate inside the flow meter; in some cases, corrosion and damage may also occur. These conditions increase the likelihood of fracturing and acidization during the metering process, resulting in measurement values that are significantly lower than the actual values. In the measurement process of vortex flowmeters, it is necessary to ensure the purity of the medium; otherwise, if saturated water vapor is present in the medium, water condensation will occur when the temperature drops. During the measurement process, if there are impurities such as dirty oil and sand particles in the medium, adhesion of these impurities to the surface of the vortex generator may occur during measurement ； If there is oil leakage in the gas path of the metering separator, a large amount of liquid will accumulate within the pipelines, which will affect the accuracy of the metering results. Therefore, when using a vortex flowmeter to measure a medium, it is necessary to ensure that the medium is clean in order to avoid affecting the measurement results.
