Advantages and disadvantages of throttling differential pressure flowmeter
2011-9-28 15:18:26

节流式差压流量计 使用的优越性 First, the superiority of the use of throttling differential pressure flowmeter

节流式差压流量计中的标准孔板结构 容易 复制, 不仅 简单牢固,性能稳定可靠, 而且 价格低廉。 The standard orifice plate structure in the throttling differential pressure flow meter is easy to copy, not only simple and firm, stable and reliable performance, but also low price. 实流校准就可使用,这在流量计中是少有的。 It can be used without real flow calibration, which is rare in flow meters.

节流式差压流量计的 适用范围广泛。 Throttle differential pressure flowmeter has a wide range of applications. 适用于全部单相流体, 同时 也可测量 部分混相流, 如气固、汽液、固液等。 Not only suitable for all single-phase fluids, but also for measuring some mixed-phase flows, such as gas-solid, vapor-liquid, solid-liquid, etc.

节流式差压流量计在 高温高压大口径和小流量 适用。 Throttling differential pressure flowmeter is suitable for both high caliber and high caliber and small flow .

④ It is not sensitive to vibration and has excellent anti-interference ability.

节流式差压流量计 使用的 局限性 Limitations of Throttle Differential Pressure Flowmeter

①The measurement accuracy is medium level in the flow meter. Due to the complexity of many factors, it is difficult to improve the accuracy.

② The range is narrow. Due to the square relationship between the instrument signal and the flow, the general range is only 3: 1 to 4: 1 .

如需 较长的直管段( 通常 指孔板、喷嘴) ,一般难以满足。 Site installation requirements are relatively high, such as long straight pipe sections ( usually orifice plates and nozzles ) , which are generally difficult to meet.

易产生泄露、堵塞 及冻结、信号失真等故障。 ④ The pressure line between the throttling device and the differential pressure display instrument is a weak link, which is prone to leakage, blockage , freezing, signal distortion and other faults.

通常也 指孔板、喷嘴) Large pressure loss ( usually also refers to orifice plate and nozzle ) .
