Introduction to scale differential pressure type flowmeter in the application of the coke oven gas measurement

Abstract: introduction to scale differential pressure type flowmeter in the coke oven gas measurement, the application of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Introduction to differential pressure type flowmeter in the application of coke oven gas measurement for the parameter selection of flow meter, we first need to understand the physical properties of fluid, because we only know the character of fluid, can better for the process to choose the appropriate flow meter, it is today. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the introduction to differential pressure type flowmeter scale in coke oven gas measurement, the application of article details. Introduction to differential pressure type flowmeter in the application of coke oven gas measurement for the parameter selection of flow meter, we first need to understand the physical properties of fluid, because we only know the character of fluid, can better for the process to choose the appropriate flow meter, today we'll talk about the application of differential pressure type flowmeter in gas measurement. Differential pressure type flowmeter in fact on the gas measurement or relatively long history, early waxing orifice plate is usually used to compare more. Under the first to introduce the first gas flow measurement of main features: 1, fluid static pressure is low, low flow velocity, allowing small pressure loss, narrow diameter method for improvement of the flow velocity is generally unacceptable. According to this characteristic, generally choose smaller pressure loss of venturi tube, commonly used have V cone flowmeter, because its continuation of the venturi V cone flowmeter and the advantages of the circular orifice, so in the measurement of this occasion is very adapt to 2, fluid, high humidity or measuring object also contains a small amount of water, do stratified flow in pipe at the bottom of the object 3, some measuring hydrogen content is high, the fluid density is small, the frequency of the output flow meter measuring time, a weak signal 4, gas generator, coal gas from coke oven generally take dope, some with less dust. Based on this feature, choose commonly before segmental orifice, but with the constant improvement of the data of V cone flowmeter, at the time of measurement with impurity gas, V cone flowmeter is reflected, the advantages of small pressure loss, good trap. 5, measurement point is located in the compressor outlet, there are certain flow pulsation. On this occasion, the output frequency of vortex flowmeter is cannot be applied. 6, fluid belongs to flammable and explosive medium, 7 on the instrument itself has explosion-proof requirements, from small to large, in view of the above features are of all pipe diameter is how to apply to differential pressure type flowmeter and everyone discuss: impurities in the gas problem in the first place, in the above are expounded, the scene before mainly adopts segmental orifice, however, is now widely used still V cone flowmeter and wedge flowmeter, major advantages in here don't do too much elaborated secondly aimed at the problem of large gas measuring range, as you know, normal orifice flowmeter measurement range in the 3-1 in this way, so take parallel pipeline measurement methods in the cover plate flow meter range than the problem. For large diameter pipeline gas measurement, mainly USES the insert flowmeter measurement, common are pig flow meter, power meter, they in the measurement for large diameter pipeline gas, have economy better advantage. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
