Features
The FL-3000 and FL-3100 Series flowmeters are designed for applications which involve corrosive or ultra-pure fluids. The meters are equipped with built-in PTFE needle valves with PCTFE, borosilicate glass, sapphire, and Perfluoroelastomer O-rings.
The special scale design, where a vertical line runs up the length of the scale and intersects the horizontal scale divisions, reduces parallax and eye fatigue, thus insuring high accuracy readings. The front polycarbonate resin shield also acts as a magnifying glass, all of which makes these Variable Area Flow Meters, far easier to read than standard industrial designs.
SPECIFICATIONS
Accuracy: ±2% FS (±5% FS for models FL-3007SA and FL-3145SA)
Repeatability: ±0.25% FS
Max. Pressure: 100 psig
Max. Temperature: 66°C (150°F)
Connections: 1/8 FNPT
Mounting: Panel mount or optional tripod base
Height/Center to Center Port Distance: 65 mm (6.156'/5.156'); 150 mm (10.469'/9.469')
*Minimum flow rate is 10% of maximum rate shown.

i ordered them for someone else to use
so I don't know the outcome. They looked fine and appear to be good quality

Does Omega provide electronic copies of their flow data sheets (flow rates corresponding to scale readings on the rotameter)? Thanks!
Thanks for your question; unfortunately, we do not. Data sheets have to be requested by email or over the phone.

What is the float material for the PTFE Variable Area Flow Meter model FL-3000 or FL-3100?
Thank you for your inquiry. The float material is a sapphire and red in color.

For the included valve, can you provide a flow coefficient (i.e. pressure drop for a given flow) for the wide open condition? The data sheet lists 1 psid at 0.2 gpm for an "Accessory" PTFE valve, but is this the same as default included valve?
Thank you for your inquiry about the rotameters. Please send an email to the Flow Group at flow@omega.com and can provide the pressure loss for a specific rotameter you are interested since it varies with the media type.

These flow meters used to mount with 2 small screws in the back , now they dont have the threaded holes
The PTFE rotameters do not have 2 small screws, only the holes to thread or mount the rotameter.

Is this flow meter available in a top valve version?
Thank you for your inquiry. Please e-mail flow@omega.com with your process conditions and our Flow Engineers can advise if the modification can be done.
