How to ensure the measurement accuracy of the intelligent vortex flowmeter during installation

Abstract: The information on how to ensure the measurement accuracy of the intelligent vortex flowmeter during installation is provided by the excellent flowmeter and flowmeter production and quotation manufacturers. The intelligent vortex flowmeter is mainly used for the flow measurement of the medium fluid in the industrial pipeline, such as gas, liquid, steam and other media. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. Vortex flowmeters use piezoelectric stress. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to ensure the measurement accuracy of the intelligent vortex flowmeter during installation. The intelligent vortex flowmeter is mainly used for the flow measurement of the medium fluid in the industrial pipeline, such as gas, liquid, steam and other media. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. The vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃～+250℃. Vortex flowmeter is a new type of flowmeter with international advanced level, which is successfully developed based on the principle of Karman vortex flow. Because it has the incomparable advantages of other flowmeters, it has developed rapidly since the 1970s. According to relevant data, it has been widely used in various fields. It will dominate the flow instrument in the future, and it is the most ideal alternative to the orifice flowmeter. 1. Vortex flowmeters are calibrated one by one before leaving the factory. Since the outflow coefficient is calculated by the software, the final comparison calculated by the computer is different from the scene environment. Therefore, in order to ensure the measurement accuracy, it is recommended to Each flowmeter is calibrated in real flow, and the calibrated outflow coefficient is compared with the calculated result, and the difference is calculated and modified. 2. Modification of the Reynolds number, there is a positive relationship between the flow coefficient of the vortex flowmeter and the Reynolds number. When the mass fluid changes, the Reynolds number changes in inverse proportion, thus causing the flow coefficient to change. 3. The influence of temperature on the vortex flowmeter and its modification. The change of fluid temperature causes the change of density, which leads to the change of the relationship between differential pressure and flow rate. The modification of temperature change is to use the temperature instrument to measure the on-site temperature and then output it to the secondary instrument to modify the error caused by the temperature change. 4. Collapsible proofreading. When the vortex flowmeter measures the flow of steam and gas, the collapsible calibration of the fluid must be carried out. For the detailed calibration coefficient, please refer to the throttling installation design manual. 5. Calculation of steam mass flow, when the vortex flowmeter measures steam, the flow value is first obtained from the differential pressure signal, and then the density is obtained from the steam temperature and pressure values ​​to calculate the steam flow quality.
