Abstract: the boiler steam mass flow rate measurement information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Boiler steam mass flow rate measurement of vortex flowmeter are generally selected measuring boiler steam volume flow, *, boiler steam is saturated steam commonly, not very high, the temperature of the vortex flowmeter at 280 degrees temperature stability is very good. Second, the steam boiler. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the boiler steam mass flow rate measurement details. Boiler steam mass flow rate measurement of vortex flowmeter are generally selected measuring boiler steam volume flow, *, boiler steam is saturated steam commonly, not very high, the temperature of the vortex flowmeter at 280 degrees temperature stability is very good. Second, the boiler steam pressure is not very big, NTF - G of vortex street flowmeter pressure is 1 by default. 6 mpa, generally meet the requirements, even if there is 2. 5 mpa measurement requirements, also can meet, NTF - G zui big pressure rating of the vortex flowmeter can do 6. 3MPa。 Relative to the throttle differential pressure flowmeter, vortex flowmeter has the following advantages: 1, simple structure, strong, easy installation and maintenance. No throttle differential pressure flowmeter to regards, three valves group and accessories, there is no leaking, blocking and freezing, and so on and so forth. 2, high precision. As a general rule, be ( 1 - 1. 5%) R3, wide measuring range, according to the parameter selecting good caliber, range than can be done systematically, and the differential pressure type 3:14, small pressure loss, only about a quarter of the throttle differential pressure flowmeter 5, the output is proportional to the flow of the pulse signal, no zero drift 6, RE only within a certain range, the frequency output is not affected by the physical properties and composition of instrument coefficient and triangular prism (only Vortex sound body) Related to crown reaches the shape, size. Now in the production of enterprises, the boiler steam flow rate measurement is generally mass flow. And we all know, the quality is the product of volume and density, if the steam density is constant, or temperature fluctuation is not big, the NTF - directly G internal set density, vortex flowmeter can directly read out the mass flow of saturated steam. However, the actual work condition, the boiler steam temperature fluctuations ( Pressure changes) Is relatively large, if inaccurate set a density, it is concluded that the steam mass flow rate is not accurate, according to the experience, do not do temperature pressure compensation ( Temperature compensation, pressure compensation) (mass flow of saturated steam boiler Tons/hour T/h, how many tons of total T) The error may reach more than 80%, even more. Therefore, measuring the mass flow of saturated steam boiler, do the temperature and pressure compensation when necessary. Currently the industry use with compensation of vortex flowmeter is divided into two kinds, one kind is vortex flowmeter of temperature, pressure compensation integration, namely, the temperature and pressure compensation directly to do within the instrument, the disadvantage of this approach is obvious, the service life of the instability of measurement and instrumentation, precision have some defects. NTF - G, vortex flowmeter is the output frequency of vortex flowmeters, deserve to go up pressure transmitter, temperature transmitter of saturated steam mass flow rate and flow totalizer. especially measurement system, to accurately measure the mass flow of saturated steam, instrument used is stable and reliable, long life, easy maintenance, is a better choice. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
The use of vortex flow meter manufacturer mass flow meter is a great trend in today's world. What you should know is that it has become a very important part of business today.
