The pipe flow rate calculation above is for liquids. Orifice gas pipe flow rate calculations (D<5 cm, D≥5 cm) have an additional factor called expansibility.Equations The pipe flow rate calculations on this page are for orifices carrying a liquid as described in ISO (1991) and ASME (...
Coefficient used for compressible flow calculation C - coefficient of discharge Coefficient used for orifice plate based on ISO 5167 ReD- upstream Reynolds number Reynolds number calculated in front of the orifice K - resistance coefficient That you can use in pipeline calculation, as orifice is crea...
Use this calculator to quickly calculate the actual flow rate through the orifice plate flow meter with only a few inputs. This calculator performs the flow rate calculation from the measured pressure drop caused by the orifice plate inserted in the pipeline. ...
进口蒸汽流量测量喷嘴流量计,美国Texas得州进口喷嘴流量计,Orifice plate flowmeter进口流量计中国代理商:上海沪贡 喷嘴的测量是依据流体力学的节流原理。当充满管道的流体流经管道内的喷嘴时,流束将在喷嘴处形成局部收缩,从而使流速加快,静压力降低。于是在喷嘴前后便产生了压力降或叫压差。介质流动的流量愈大,在喷嘴...
The calculation was checked through software and confirmed that the data is suitable for orifice plate with bore size 27 mm. The current issue is; the transmitter of this orifice plate is reading over range "IOP" lively and DP was checked at site to be found 0.7 bar which makes sense for...
through orifice meters. Gas flow calculations include an expansibility factore, which is not present in the liquid calculation. The expansibility factor accounts for the effect of pressure change on gas density as gas flows through the orifice. Our calculation is valid for subsonic gas flow. ...

To calculate the flowrate of a fluid passing through an orifice plate, enter the parameters below. (The default calculation involves air passing through a medium-sized orifice in a 4" pipe, with answers rounded to 3 significant figures.) ...
ZY Flowmeter offers a wide range of primary differential pressure flowmeters, Orifice Plates, Orifice Plate assemblies, venturi tubes, wedge flow meter,meter run and v cone flow meters.
How Does an Orifice Plate Flow Meter Work? The orifice plate can be made of any material, although stainless steel is the most common. The thickness of the plate used (1/8 – 1/2") is a function of the line size, the process temperature, the pressure, and the differential pressure. ...
