Vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, has convenient installation and maintenance, high cost performance, the application of a wide range of features. Vortex flow meter used in petroleum, chemical, metallurgical, thermal, textile, paper and other industries of superheated steam,. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a vortex flow meter scale voltage compensation method of the article details. Vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, has convenient installation and maintenance, high cost performance, the application of a wide range of features. Vortex flow meter used in petroleum, chemical, metallurgical, thermal, textile, paper and other industries of superheated steam and saturated steam, compressed air and gas, water and liquid measurement and control. The volume of saturated steam and superheated steam under the influence of temperature and pressure is very big. Meter below to share with you about the voltage compensation method of vortex flowmeter. 1, a one-time compensation method determine the working parameters of the steam & ndash; According to temperature and pressure, vortex street flowmeter work under working state parameters to determine steam density, the density as the future of steam in the process of the flow measurement orifice * density is calculated. At work to compensate the actual changes of steam or correction, this is known as a compensation method based on one-time calculation. If in the running, the working parameters of steam consistent with the design value, the steam flow measurement accuracy can be guaranteed. If some deviation from the actual working condition parameters, the deviation is very large, even is the deviation of measurement results can be quite large. One-time compensation method, at the beginning of the automatic detection technology adopted by way of measurement, measurement result error is big, can be used as a rough measurement. This design method in the present widespread flow throttling device in the design manual is still in use. 2, on-line density compensation method with the wide application of microelectronics technology in the instrument. Computing functions of vortex flowmeter, compensation correction function, the cumulative function, historical data storage function, the digital filter function, the function, of output, digital communication function and so on can be easily implemented. Online density compensation has become a kind of indispensable basic steam metering instrument functions and is widely used. Here introduce the classification of the vapor density compensation: { 1} Saturated vapor density compensation online. Vortex flowmeter can realize the integration of temperature compensation, the temperature and pressure of saturated steam has a strict one-to-one correspondence relationship between. The density of saturated steam can be the temperature or the pressure of a single function. According to the size of the saturated steam temperature or pressure value, through the look-up table method or the formula to calculate method ( IFC1967 or IAPW - 1997). To get real-time density value. In the flow measurement, the vortex street flowmeter can choose temperature compensation or pressure compensation type flowmeter. To select flowmeter with temperature compensation capability. Open flowmeter temperature sensor, real-time detection test steam temperature, and obtained the corresponding density value. { 2} On-line density compensation superheated steam is superheated steam to saturated steam heating again after a kind of special quality of steam. It broke the inherent in the saturated steam temperature and pressure strict one-to-one relationship. Vortex street flowmeter in flow measurement in the process of superheated steam can be viewed as a single medium. Is the density of superheated steam temperature and pressure of the comprehensive function. In order to select the temperature, the vortex flowmeter pressure compensation type. In actual use, at the same time open real-time sensor measuring temperature and pressure steam temperature, pressure, density values can be according to the density of superheat steam tables or density calculation formula for accurate calculation. Meter factory as a professional research and development type flowmeter production enterprises, over the years, always adhere to the quality and brand, brand for the development of the production concept, perseverance, research, difficult, research and development of new technologies, new products constantly, for the overwhelming majority of customers with reliable quality, comply with the requirements of products, and at the same time, and many enterprises established long-term cooperative relations, set sail together with all my colleagues look forward to working with you. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
