Designing a rotameter ?

[GogiBOB]

Hi,
I am working on a project for designing different flow meters. I am designing a rotameter alone.

I did some homework and studied equations about fluid meters and mechanics but I am still not sure of where to begin.

The principle is simple but all the articles I've read only explains basic principles.

Can anyone give me good references or heads up? I am pretty clueless at this point.

I would appreciate any comments. Thanks!

You can refer to ASME PTC 19.5

Thanks Engdoitbetter,
I've looked up ASME PTC 19.5 but the document doesn't have any information about the design of rotameters.
Is there any other ASME document regarding variable area flow meters?

Thanks,

As far a sI know there should be an ASME report on fluid meters and a part of it is dedicated to variable area flow meters.
This is the link, it's an old book

My company works a lot with DP flowmeters and little on variable area ones, so I don't know if there's any standard around regarding the latter.

Hope it helps.
