The main reasons for the measurement error of the vortex flowmeter

Abstract: The information on the main reasons for the measurement error of the vortex flowmeter meter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The vortex flowmeter has been widely used in industrial production, and its role is becoming more and more important. If the measurement data is inaccurate during the use of the vortex flowmeter, the first thing to do is to judge which aspect is incorrect. Error in flow, below. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the main reasons for the measurement errors of vortex flowmeters. The vortex flowmeter has been widely used in industrial production, and its role is becoming more and more important. If the measurement data is inaccurate during the use of the vortex flowmeter, the first thing to do is to judge which aspect is incorrect. Flow error, let's discuss with you the main reasons for the measurement error of the vortex flowmeter: 1. The influence of temperature on the measurement Temperature has an impact on the measurement medium of the general flowmeter, and the temperature affects the density and viscosity of the medium. And so on, these will make the measurement results inaccurate and there will be errors. To eliminate this effect, the K coefficient is generally corrected. 2. Problems in model selection The actual model selection should choose the smallest diameter possible to improve the measurement accuracy. For example, a vortex pipeline is designed to be used by several devices. Because the process equipment is sometimes not used, the current actual use The flow rate is reduced, and the original design selection diameter is too large in actual use, which is equivalent to increasing the lower limit of the measurable flow rate. The indication cannot be guaranteed when the flow rate of the process pipeline is small, and it can be used when the flow rate is large, because it is sometimes too difficult to remodel. Large. Changes in process conditions are only temporary. Can be combined with parameter re-tuning to improve indication accuracy. 3. 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. 4. Problems in installation The main problem in installation is 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. As a flow meter manufacturer, we strive to learn new technologies from others, introduce advanced equipment, and develop more technologies to meet the needs of more customers. Chengfeng flowmeter has also gradually sold its products abroad, which is widely loved by customers. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'The main reasons for the measurement error of the vortex flowmeter'
