Brief Discussion on the Application of Differential Pressure Flow Meter in Coke Oven Gas Measurement

Abstract: The application information of differential pressure flow meter in coke oven gas measurement is provided by excellent flow meter and flow meter manufacturers. Talking about the application of differential pressure flowmeter in coke oven gas measurement For on-site parameter selection flowmeter, we must first understand the physical properties of the fluid, because only by understanding the characteristics of the fluid can we better select the appropriate flow rate for the process count, today. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is a brief introduction to the application of differential pressure flowmeters in coke oven gas measurement. Talking about the application of differential pressure flowmeter in coke oven gas measurement For on-site parameter selection flowmeter, we must first understand the physical properties of the fluid, because only by understanding the characteristics of the fluid can we better select the appropriate flow rate for the process Meter, today we will talk about the application of differential pressure flowmeter in gas measurement. Differential pressure flowmeter actually has a long history in gas measurement. In the early days, round orifice plates were generally used more. First of all, let me introduce the main characteristics of gas flow measurement: 1. Low hydrostatic pressure, low flow rate, small allowable pressure loss, generally not allowed to reduce the diameter of the pipe to increase the flow rate. According to this characteristic, the Venturi tube with smaller pressure loss is generally selected. The commonly used V-cone flowmeter is the V-cone flowmeter because it continues the advantages of the Venturi and annular orifice plate, so it is very suitable for the measurement of this occasion. 2. The humidity of the fluid is high, and some measurement objects also contain a small amount of water, and stratified flow is performed at the bottom of the pipe. 3. Some measurement objects have high hydrogen content and low fluid density. When the flowmeter with frequency output is used, the signal is weak. 4. The gas produced by gas generators, coke ovens, etc. generally contains viscous substances, and some also contain less dust. According to this characteristic, the circular orifice plate was generally used in the past, but with the continuous improvement of the data of the V-cone flowmeter, the advantages of the V-cone flowmeter are reflected when measuring the gas containing impurities. Good blocking. 5. When the measurement point is located at the outlet of the compressor, there is still a certain flow of pulsation. In this case, the vortex flowmeter with frequency output cannot be used. 6. The fluid is a flammable and explosive medium, and the instrument itself has explosion-proof requirements. 7. Various pipe diameters from small to large have the above characteristics. Let’s discuss how to apply the differential pressure flowmeter. The problem of impurities is also explained above. In the past, round orifice plates were mainly used on the site. However, V-cone flowmeters and wedge flowmeters are widely used now. The main advantages will not be elaborated here. The second is In view of the problem of large gas measurement range, we all know that the normal measurement range of orifice plate flowmeter is 3:1, so the method of parallel pipeline measurement is adopted on site to make up for the small range ratio of plate flowmeter. For the measurement of large-diameter pipeline gas, the insertion flowmeter is mainly used for measurement. The common ones are Annubar flowmeter and Verabar flowmeter. They have economic comparisons for large-diameter pipelines in measuring gas. Good advantage. The above is the whole content of this article.
