Boiler steam mass flow measurement

Abstract: The measurement information of boiler steam mass flow is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The measurement of boiler steam mass flow generally uses vortex flowmeter to measure the volume flow of boiler steam. * The steam from the boiler is generally saturated steam, and its temperature is not very high. The vortex flowmeter has good stability at 280 degrees. . Second, boiler steam. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the measurement article of boiler steam mass flow. The measurement of boiler steam mass flow generally uses vortex flowmeter to measure the volume flow of boiler steam. * The steam from the boiler is generally saturated steam, and its temperature is not very high. The vortex flowmeter has good stability at 280 degrees. . Second, the pressure of boiler steam is not very large. The default pressure of NTF-G vortex flowmeter is 1.6MPa, which generally meets the requirements. Even if there is a measurement requirement of 2.5MPa, it can be satisfied. NTF-G vortex flowmeter The maximum rated pressure can be achieved 6.3MPa. Compared with the throttle differential pressure flowmeter, the vortex flowmeter has the following advantages: 1. The structure is simple, firm, and easy to install and maintain. There is no need for throttling differential pressure flowmeters to accessories such as Yaguan and three-valve manifolds, and there is no leakage, blockage and freezing. 2. High precision. Generally (1-1.5%) R3, the measurement range is wide, and the caliber is reasonably selected according to the parameters. The range ratio can be 20:1, while the differential pressure type is only 3:14, and the pressure loss is small, which is the throttling differential pressure flow. About 1/4 of the meter 5. Output pulse signal proportional to flow rate, no zero drift The shape and size of Cunard are related. At present, in the production of enterprises, the flow rate of boiler steam is generally measured by mass flow rate. And we all know that mass is the product of volume and density. If the density of the steam is constant, or if the temperature fluctuation is not large, the density can be directly set in the NTF-G vortex flowmeter, and it can be read directly. Mass flow of saturated steam. However, in the actual working state, the temperature fluctuation (pressure change) of the boiler steam is relatively large. If an inaccurate density is set, the obtained steam mass flow is inaccurate. The error of the saturated steam mass flow (ton/hour T/h, how many tons T in total) of the boiler with temperature and pressure compensation (temperature compensation, pressure compensation) may reach more than 80%, or even larger. Therefore, it is necessary to measure the mass flow of the saturated steam of the boiler for temperature and pressure compensation. At present, there are two types of vortex flowmeters with compensation used in the industry. One is the vortex flowmeter with integrated temperature and pressure compensation, that is, the temperature and pressure compensation are directly done in the instrument. The shortcomings of this method are obvious. , There are certain defects in the instability of measurement and the service life and accuracy of the instrument. NTF-G vortex flowmeter is a vortex flowmeter with frequency output, coupled with pressure transmitter, temperature transmitter and flow totalizer to form a saturated steam mass flow measurement system to accurately measure the quality of saturated steam Flow, stable and reliable use of instruments, long life, easy maintenance, is a better choice for enterprises. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Measurement of Boiler Steam Mass Flow'
