Industry Information
Difference between balanced orifice plate and standard orifice plate
2011-6-3 9:15:35

The balanced orifice plate flowmeter is a new type of flowmeter newly developed in recent years.Based on the standard orifice plate, a four-hole circulation method is adopted, which greatly avoids the large pressure loss of the standard orifice plate in the field and requires long straight pipe sections. Disadvantages, and in terms of measurement, the accuracy of the standard orifice plate has been greatly improved.The advantages of the industrial measurement of the balanced flow meter will be described in detail below.
1.The field measurement of the balanced flow meter adopts a symmetrical porous structure, which can actually balance the fluid and reduce eddy currents and vibrations. Compared with the on-site measurement of the orifice flow meter, these advantages alone have improved a lot, and the measurement range is wide. It solves the defects of the differential pressure flowmeter and is an upgrade of the standard orifice plate.
2.Everyone knows that when a standard orifice flowmeter is used in the field, the pressure loss is large, and the high requirements of the front and back straight pipe sections are the main reasons that restrict its development. However, due to its own structural problems, the balance flowmeter has basically realized the conversion. The starting pressure loss is about 1/4 of the standard orifice plate, and the requirements for straight pipe sections are only about 3D after the first 3D. Technical hotline: 0517-86901324
200 ,最大雷诺数大于 10 7 β 值可选 0.25 0.90 This is often 1: 3, and the on-site measurement range often exceeds this range.This often limits the application of standard orifice plates, and the normal ratio of the range of the balanced orifice plate flowmeter is about 20: 1.Sometimes, The upper limit flow is even more unlimited. Its minimum Reynolds number can be lower than 200 and the maximum Reynolds number is greater than 10 7. The β value can be selected from 0.25 to 0.90 .
β 值长期保持不变,整个仪表无可动部件,因此可以长期保持稳定性.其次还具有标准孔板的所有测量优势,适合高温高压的测量场合,基本适用于所有现场介质的测量. 4, good long-term stability, because its turbulent shear force is significantly reduced, greatly reducing the direct friction between the medium and the throttle, its β value remains unchanged for a long time, the entire instrument has no moving parts, so it can be long-term Maintain stability.Second, it also has all the measurement advantages of standard orifice plates, suitable for high-temperature and high-pressure measurement occasions, and basically suitable for all field media measurements.
The use of balanced flow meters in the field is being accepted by field maintenance personnel. From the sales report of Jiangsu Dongxiang Meter, sales are gradually increasing. Dongxiang people will continue to work hard to fight for our first-class products to serve our customers. . Welcome to inquire: 18952332920
