Float reading

I corrected this several years ago and see that it was changed. Every sphereical rotameter I've ever purchased (many) is meant to be read at the center of the bead. A sphere has only one widest point...the center. A cylinder has many widest points, so you read it at the top of the widest section...the top of the float. For a pyramid shaped float it's read at the widest point...the bottom of the pyramid.Beakerboy (talk) 20:11, 15 April 2010 (UTC)[reply]

If we wanted to be semantic about it, we could say that gases are fluids and that listing both is redundant, but I'm not that pedantic. Thanks for catching my spelling error on separate though... -- Kowh 06:57, 25 Apr 2004 (UTC)

It's an encyclopedia, pedantic is good and redundant is bad. I made that change, as well as altering the format slightly. The Table of Contents didn't seem necessary for an article of this length. The rotameter is a cool concept. A disadvantage that I couldn't put concisely is that the operating pressure of the fluid has to be less than the yield strength of the glass. --Brockert 09:11, Apr 25, 2004 (UTC)

How do one caliberate the rotameter? i dont know —Preceding unsigned comment added by 59.96.20.252 (talk) 11:28, 24 October 2008 (UTC)[reply]

Is Rotameter a Generic Trademark?

Apparently, there used to be a page called Variable area meter which has been merged with Flow measurement. There is also a page called Thorpe tube flowmeter, covering the simpler sort of ball-in-tapered-tube device used for less precise measurement of gas flow. This page is entitled Rotameter but is about Variable area meters in general; I do not think this is appropriate.
