Questions regarding the flow calculation formula for orifice plate flow meters
Thread Content
In the formula for orifice plate flow meters, q=C*A*（2*ΔP/ρ）^0.5, what does C represent?
~~~C is the flow coefficient~~~
How is this value generally chosen? Are there any empirical data?
It is recommended to have the supplier calculate the orifice plate values directly; they are professional manufacturers of such plates and have much greater expertise in areas such as the isentropic exponent, effective orifice diameter ratio, and throttle hole diameter. Your own calculations are likely to be inaccurate, while manufacturers generally use ISO-5167 or the latest standard GB/T2624-2006 for these calculations
Taking a look at the book \"Design Manual for Flow Measurement Throttling Devices\" will be helpful to you.
Thank you, I’ll go download it first and take a look. If I still have any issues, I’ll ask you for help again :)
I helped someone upload this book on a forum, but I deleted it right away; now I have to download it again. Ugh:L
Orifice plates are standard components; generally, once all the necessary parameters are provided to the manufacturer, they will use software to carry out the calculations directly
For orifice plate calculations, it’s better to consult the manufacturer. If you need help, feel free to contact me; I have the necessary calculation software!
Give me the orifice plate calculation software so I can study it. zhangshiwei3033@163.com
