Can these be used with inert gases or solely just air?
Hi, thanks for connecting with us! You can use these meters with inert dry gases other than air but you will have to correct for the specific gravity. If you need help calculating this, please contact our Flow Department at flow@omega.com.

What is the pressure drop of a FL-2012 (0.2 to 2.5) flow meter?
Thank you for your question?
The max drop is 3 PSI for the FL-2012

Can I use an equation to determine the flow at non-standard pressure and temperature? On another MFG's site I saw Q2 = Q1 * sqrt (P1*T2/(P2*T1)). Is that equation correct for this flowmeter?
Send us an email to flow@omega.com. We can provide correct equation on a PDF form.

We are using FL-2012 not with a ball float but with a conical float. Do we have to determine the flowrate by reading the center, top or bottom of the conical float?
Thank you for your inquiry! For conical floats the reading will be taken from the top
