Comparison of Balanced Orifice Flow Meters and Standard Orifice

Abstract: The comparison information between the balance orifice flow meter and the standard orifice is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Balanced orifice flowmeter is a new type of flowmeter developed in recent years. On the basis of standard orifice plate, it adopts the method of four-hole flow, which greatly avoids the large pressure loss of standard orifice plate in the field, and requires long straight pipe sections before and after. Cons, but also better than standard in terms of measurement. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the comparison article of the balance orifice flowmeter and the standard orifice. Balanced orifice flowmeter is a new type of flowmeter developed in recent years. On the basis of standard orifice plate, it adopts the method of four-hole flow, which greatly avoids the large pressure loss of standard orifice plate in the field, and requires long straight pipe sections before and after. In addition, the accuracy of the measurement has been greatly improved compared with the standard orifice plate. The following will give you a detailed introduction to the advantages of industrial measurement of the balance flowmeter. 1. The balance flowmeter adopts a symmetrical porous structure for on-site measurement, which can conduct Actual balance, reducing eddy current and vibration, compared with the on-site measurement of the orifice flowmeter, these advantages alone have improved a lot, and at the same time the measurement range is wide, which fundamentally solves the defects of the differential pressure flowmeter, which is the standard orifice flowmeter. Upgrade.2, we all know that when the standard orifice flowmeter is used in the field, the pressure loss is large, and the high requirements of the front and rear straight pipe sections are the main reasons that restrict its development. However, due to its own structural problems, the balanced flowmeter fundamentally realizes For conversion, the starting pressure loss is about 1/4 of the standard orifice plate, and the requirements for the straight pipe section are only about 3D in the front and 1D in the back. It is usually 1:3, and the field measurement range often exceeds this range. It limits the application of standard orifice plate, and the normal ratio of the range of balanced orifice plate flowmeter is about 20:1. In some cases, the upper limit flow is unlimited, and 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. 3, the long-term stability is good, due to the obvious reduction of the turbulent shear force, the direct friction between the medium and the throttling member is greatly reduced, and theβThe value remains unchanged for a long time, and the entire instrument has no moving parts, so it can maintain stability for a long time. Secondly, it also has all the measurement advantages of standard orifice plates, which are suitable for high temperature and high pressure measurement occasions, and are basically suitable for the measurement of all on-site media. Balanced flowmeter Nowadays, the use in the field is being accepted by the field maintenance personnel. From the sales report, the sales volume is gradually increasing. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
