The difference between a symmetrical flow meter and an orifice flow meter

Abstract: The difference information between symmetrical flow meter and orifice flow meter is provided by excellent flow meter and flow meter manufacturers. Comparison of Balanced Flowmeter and Orifice Plate Balanced flowmeter is suitable for almost all fluid measurements, and is a revolution in fluid measurement technology. At present, balanced flowmeters have been widely used in petroleum, chemical, metallurgy, electric power, natural gas, water treatment and other industries. balance flow. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the difference between symmetrical flowmeters and orifice flowmeters. Balanced flowmeter compared with orifice plate Balanced flowmeter is suitable for almost all fluid measurement, which is a revolution in fluid measurement technology. At present, balanced flowmeter has been widely used in petroleum, chemical, metallurgy, electric power, natural gas, water treatment and other industries. The balance flowmeter is a new type of flowmeter developed in recent years. On the basis of the standard orifice plate, the four-hole flow method is adopted, which greatly avoids the disadvantages of large pressure loss and long straight pipe sections in the field of standard orifice plate. And in terms of measurement, the accuracy of the standard orifice plate has been greatly improved. The following will give you a detailed introduction to the advantages of the balance flowmeter in industrial measurement. When the standard orifice flowmeter is used on-site, the pressure loss is large, and the front and rear are straight. The high requirement of pipe sections is the main reason that restricts its development. However, due to its own structural problems, the balanced flowmeter has fundamentally realized the conversion. The pressure loss is about 1/4 of the standard orifice plate, and the straight pipe section requirements are only the first 3D After about 1D. The orifice plate range ratio is usually 1:3-1:10, and the field measurement range often exceeds this range. This also limits the application of standard orifice plates in many cases, and the range of balanced orifice flowmeters The normal ratio is about 20:1. In some cases, the upper flow rate is unlimited, the minimum Reynolds number can be lower than 200, and the maximum Reynolds number is greater than 107;βThe value can be selected from 0.25 to 0.90. The on-site measurement of the balance flowmeter adopts a symmetrical porous structure, which can actually balance the fluid and reduce the eddy current and vibration. Compared with the on-site measurement of the orifice flowmeter, these advantages alone have improved a lot. At the same time, the measurement range is wide, which fundamentally solves the problem. It is an upgraded version of the standard orifice plate. The balance flowmeter has good long-term stability. Due to the obvious reduction of its turbulent shear force, the direct friction between the medium and the throttling member is greatly reduced. ThatβThe value remains unchanged for a long time, and the whole instrument has no moving parts, so it can maintain stability for a long time. Secondly, it also has all the measurement advantages of the standard orifice plate, which is suitable for high temperature and high pressure measurement occasions, and is basically suitable for the measurement requirements of all on-site media. The installation forms of the balance flowmeter are: pipe section type, pipe section wafer type, flange wafer type, welding type, double flange type, and square tube type. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
