Rated 5 out of 5 by from Effective little flow meter This is an accurate, and easy to use flow meter with adjustable valve. The workmanship is good, it’s working great for my application. I did not look at other options from Omega, but it would be nice to have options on I/O locations, such as side, or end. This one had both in, and out in the back. This can make tings a little crowded to mount the unit, and set up the I/O. Overall I am happy with this unit, it is doing exactly what I was hoping for.

Rated 5 out of 5 by from Excellent meter, good value. We've been using these flow meters for about 7 years now. Have installed at least 50 in systems that we build. Never a problem.

Rated 4 out of 5 by from Good, basic low-flow flowmeter Good, simple flowmeter for low-flow applications. Not the easiest to mount well onto a panel.

Rated 1 out of 5 by from Wrong Picture... The flow meter picture shows the model for water, inducing to wrong choice.

What is the pressure drop of a FL-2012 (0.2 to 2.5) flow meter?

Asked by: jenn
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?

Asked by: Engineer2020
Send us an email to We can provide correct equation on a PDF form.

Can these be used with inert gases or solely just air?

Asked by: amyfng
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

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?

Asked by: bob100
Thank you for your inquiry! For conical floats the reading will be taken from the top
