It has the characteristics of convenient installation and maintenance, high cost performance and wide application range. Vortex flowmeters are used in the measurement and control of superheated steam, saturated steam, compressed air and general gases, water and liquids in petroleum, chemical, metallurgical, thermal, textile, papermaking and other industries. The volume of saturated steam and superheated steam is affected by temperature And stress has a big impact. The following flowmeter will share with you the realization method of voltage regulation compensation of vortex flowmeter. 1. One-time compensation implementation method First determine the working parameters of steam—Temperature and pressure, the vortex flowmeter determines the density of the steam in the working state according to the working parameters, and the density is used as the maximum density of the steam in the future flow measurement process for orifice calculation. The actual change of steam is no longer compensated or corrected during the work, which is the so-called one-time calculation compensation method. If during operation, the working parameters of steam are consistent with the set values ​​during design, the accuracy of steam flow measurement can be guaranteed. If the parameters deviate from the actual working conditions, or even deviate greatly, the deviation of the measurement results may be very large. The one-time compensation method, the measurement method adopted in the early stage of the development of automatic detection technology, has a large error in the measurement result and can be used as a rough measurement. Such design methods are still used in the design manuals of flow throttling devices that are currently widely popular. 2. The realization method of online density compensation is widely used in the instrument with the microelectronic technology. The calculation function, compensation and correction function, accumulation function, historical data storage function, digital filtering function, output function, digital communication function and so on of the vortex flowmeter can be easily realized. On-line density compensation has become an essential basic function of steam metering instruments and is widely used. The following introduces the classification of steam density compensation: {1} Online density compensation for saturated steam. Vortex flowmeter can realize integrated temperature and pressure compensation, and there is a strict one-to-one correspondence between the temperature and pressure of saturated steam. The density of saturated steam can be a single function of its temperature or its pressure. According to the temperature value or the pressure value of the saturated steam, the real-time density value can be obtained by the look-up table method or the formula calculation method (IFC1967 or IAPW-1997). In flow measurement, the vortex flowmeter can be realized by temperature compensation or pressure compensation flowmeter. To choose a flowmeter with temperature compensation function. Turn on the temperature sensor of the flowmeter to detect the measured steam temperature in real time, so as to obtain the corresponding density value. {2} Superheated steam online density compensation Superheated steam is a kind of steam with special quality obtained by reheating saturated steam. It breaks the strict one-to-one relationship between temperature and pressure inherent in saturated steam. Vortex flowmeter can treat superheated steam as a single medium in the flow measurement process. The density of superheated steam is a combined function of its temperature and pressure. When ordering the vortex flowmeter, select the temperature and pressure compensation type. In actual use, the temperature and pressure sensors are turned on at the same time to measure the steam temperature and pressure value in real time, and the density value can be accurately calculated according to the superheated steam density table or density calculation formula.
