Do you know the reason that affects the inaccuracy of the vortex flowmeter?

For the vortex flowmeter, do you know what is the specific reason that affects the measurement inaccuracy? The editor will take you to understand: there are often vortex flowmeter users who respond to us that the vortex flowmeter display is inaccurate, thinking that it is a quality problem of the vortex flowmeter. In fact, the reasons that affect the inaccuracy of the flowmeter measurement mainly include: The three aspects of selection, installation and parameter setting direction, and we, as a vortex flowmeter manufacturer, bring this knowledge to everyone for everyone to learn. Introduce in detail the treatment method of inaccurate display of vortex flowmeter, hoping to help users better apply products: 1. Factors that will affect the selection of models  Some vortex flowmeter sensors are selected in diameter or after design selection Due to changes in process conditions, a larger specification is selected, and the actual selection should be as small as possible to improve the measurement accuracy. 2. Factors affecting installation   The vortex flowmeter is mainly because 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. Influencing factors of parameter setting  The indication of the vortex flowmeter is wrong due to the wrong parameter. The wrong parameter makes the calculation of the full-scale frequency of the secondary instrument wrong. The full-scale frequency makes the indication fluctuate in a large range and cannot be read, and the inconsistency of the parameters on the data affects the determination of the parameters. 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, causing the geometry and size to change, so the flow rate The coefficients also change accordingly, so pay attention to cleaning up in use. I hope the above content can help you, pay attention to me, and get more flow meter knowledge.
