Vortex flowmeters have been widely used in industrial production and their role is becoming more and more important. If the measurement data is inaccurate in the use of vortex flowmeters, the first thing to do is to judge that the aspect is incorrect. Flow error, below, and the Shunda flow meter and everyone to discuss the vortex flow meter measurement error main reasons: 1, the impact of temperature on the measurement The temperature will affect the general flowmeter measurement medium. The temperature will influence the density and viscosity of the medium, which will make the measurement result inaccurate and error. Elimination of this effect is generally a correction of the K-factor. At present, some manufacturers' flowmeters have fixed temperature corrections and real-time temperature corrections in software. 2. Effect of inconsistency between internal flowmeter and internal flowmeter in vortex flowmeter piping 3, the problem of selection The actual sizing should choose the smallest possible caliber to improve the measurement accuracy. For example, a vortex street pipeline is designed to be used by several equipments. Because some of the equipment of the process is sometimes not used, the current actual usage flow rate is reduced, resulting in actual use. The original design selection aperture is too large, which is equivalent to the increase in the lower limit of the measurable flow, the process pipeline can not guarantee when the flow is small, can also be used when the flow is large, because if you want to re-transformation is sometimes too difficult. Process conditions change only temporary. The re-tuning of the parameters can be combined to improve the indication accuracy. 4. Effect of vortex generating body vortex surface accumulation on vortex street flowmeter If there are viscous particles in the fluid to be measured, it may gradually accumulate on the flow-in surface of the vortex generator, causing changes in its geometry and dimensions, and thus the flow coefficient will also change accordingly. Therefore, it is necessary to pay attention to cleaning during use. 5, installation problems The installation problem is mainly the length of the straight pipe section in front of the vortex flowmeter sensor. If the length is not enough, the measurement accuracy will be affected. 6, the reasons for the parameter setting direction Incorrect product parameters cause the instrument to indicate an error. The parameter error makes the secondary instrument full-scale frequency calculation error, the full-scale frequency is similar to the indication is not allowed for a long time, and the full-scale frequency of the actual full-scale frequency calculation indicates that the full-scale frequency fluctuates widely and cannot be read, but the parameters on the data The inconsistency has affected the final determination of the parameters, and finally determined the parameters by recalibrating and comparing with each other to solve such problems.
