How to deal with inaccurate display of vortex flowmeter

Abstract: The information on the inaccurate processing method displayed by the vortex flowmeter meter is provided by the excellent flowmeter and flowmeter manufacturer and quotation manufacturer. The reasons for the inaccurate display of the vortex flowmeter mainly include three aspects: model selection, installation and parameter setting direction. As a loyal user of the flowmeter, you should learn some processing methods appropriately. Today we will introduce the inaccuracy of the vortex flowmeter in detail. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The reasons for the inaccurate display of the vortex flowmeter mainly include three aspects: model selection, installation and parameter setting direction. As a loyal user of the flowmeter, you should learn some processing methods appropriately. Today, we will introduce the treatment method of inaccurate display of vortex flowmeter in detail, hoping to help users better application products. 1. Problems in selection: Some vortex sensors have a larger size in the selection of caliber or due to changes in process conditions after design and selection. The actual selection should choose the smallest caliber to improve the measurement. Accuracy, for example, a vortex pipeline is designed to be used by several equipments. Due to the fact that some of the equipment in the process are sometimes not used, the current actual flow rate is reduced. The lower flow limit of the process pipeline cannot be guaranteed when the flow rate is small, and it can be used when the flow rate is large, because it is sometimes too difficult to remodel. The change of process conditions is only temporary. Can be combined with parameter re-tuning to improve indication accuracy. 2. Installation problems: the main reason is that the length of the straight pipe section in front of the sensor is not enough, which affects the measurement accuracy. For example, the straight pipe section in front of the sensor is obviously insufficient. Since Fic203 is not used for measurement, it is only used for control, so the current accuracy can be used equivalent to downgrade use. 3. Reasons for the direction of parameter setting: The indication of the instrument is wrong due to the wrong parameters. The wrong parameters make the calculation of the full-scale frequency of the secondary instrument wrong. The full-scale frequency makes the indication fluctuate in a wide range and cannot be read, and the inconsistency of the parameters on the data affects the final determination of the parameters. Finally, the parameters are determined by re-calibration and mutual comparison, which solves this problem. 4. The influence of accumulation on the upstream surface of the vortex generating body of the vortex flowmeter If there are viscous particles in the measured fluid, they may gradually accumulate on the upstream surface of the vortex generating body, so that the geometry and size of the vortex generating body will change. The coefficients also change accordingly, so pay attention to cleaning up in use. 5. The influence of temperature on the measurement The influence of temperature change on the geometric size change of the measuring body consists of two parts, one is caused by the change of the width of the vortex generating body; the other is caused by the change in the pipeline. To eliminate this effect, the K coefficient is generally corrected. At present, the flowmeters of some manufacturers have fixed temperature correction and real-time temperature correction in the software. The flowmeter manufacturers have a group of professional high-tech talents who have been engaged in the design, development, installation and commissioning of automatic control research for a long time. A satisfactory complete system has been obtained. With a strong professional team, accumulated rich technology and management experience, it can provide users with technical services quickly and conveniently. At the same time, a professional sales and after-sales service team has been established to provide users with professional and systematic high-quality services in an all-round way. The company has strong technical force, advanced processing technology, complete testing methods, and stable product quality. With accurate and reliable products and perfect after-sales service system, it has won the trust of many users. The above is the entire content of this article.
