Supported Applications
The Omega FLK-2000 Series comprises acrylic variable area flow meters designed for the measurement of non-hazardous fluids, specifically air and water. These instruments are intended for applications requiring visual indication of flow rates within defined pressure and temperature limits.
Operating Conditions & Performance
The series is rated for operation at pressures up to 145 PSI (1000 kPa) and process temperatures up to 140°F (60°C). Accuracy across the FLK-2201 to FLK-2224 models is specified as ± 4% Full Scale. The meters utilize clear acrylic bodies with brass fittings, valves, and silicon O-rings for elastomers.
Flow ranges documented in the series specifications include:
- Air (SCFH): .2 - 2 SCFH through 25 - 200 SCFH
- Air (LPM): .1 - 1 LPM through 10 - 100 LPM
- Water (SCCM): 6 - 60 SCCM, 16 - 160 SCCM, and 25 - 250 SCCM
- Water (GPH): 0.25 - 25 GPH through 1.6 - 16 GPH
Floating elements are available in black agate or stainless steel.
Critical Installation Constraints
- Fluid Compatibility: Do not use hazardous fluids; the meter is designed for non-hazardous applications only.
- Cleaning Restrictions: Solvents must not be used to clean the meter as they will attack the acrylic and destroy the unit.
- Torque Limits: Inlet/outlet fittings must be torqued to 60 in-lbs maximum. Mounting inserts (10-32UNF) require slotted screws torqued to a maximum of 35 in-lbs.
Configuration Options
The series offers multiple model codes corresponding to specific flow ranges for air and water. Variants include standard configurations (e.g., FLK-2201) and models with the "NV" suffix, indicating distinct variant options within the same dimensional envelope.
- Housing Material: Clear Acrylic
- Fittings & Valves: Brass
- Elastomers: Silicon O-rings with brass fittings
- Floats: Black agate or Stainless Steel
- Mounting Inserts: 10-32UNF thread size
The documented dimensional envelope for the FLK-2201 to FLK-2224 models includes an overall height (C) of 4.01 IN / 102 mm and a width (D) of 3.03 IN / 77 mm.
Key Product Differences
The series encompasses model numbers FLK-2201 through FLK-2264, covering various flow ranges for air and water as detailed in the specification tables. The primary variation between models is the calibrated range of the float assembly to match specific SCFH, LPM, SCCM, or GPH requirements.
Model codes are structured by media type (Air vs. Water) and unit system (SCFH/LPM for air; SCCM/GPH for water). For example, FLK-2201 covers .2 - 2 SCFH Air, while FLK-2218 covers 6 - 60 SCCM Water.

Top Quality Product!
These are our go-to for our fermentation system! They allow precision and accuracy to dial in the exact airflow our individual ferments require.

Solid Quality Rotometer and Great Price
Solid quality rotometer. First time buying from Omega. Good customer service, better pricing than competition and quick delivery which allowed me to drop ship and install at the field site to get the air flow properly set for the process.

worked perfect
This Acrylic Flow Meter was just as described. It also worked perfect for our application.

What is the primary difference between the 'FLK-' flow meters and the 'FL-' flow meters? I see the inlet pressure difference but is there some reason for choosing, for example, the FL-2011 (0.1-1 LPM) over the FLK-2211 (also 0.1-1 LPM)?
Thank you for your inquiry! These meters are very similar and are interchangeable in many applications. The meters differ slightly in wetted materials and pressure which are the only major differences.

FLK-2215 are the 1/8 npt male or female. Where are panel mounting holes located dimensional and what size are they? Can I get a specification/dimensional drawing pdf?
Thank you for your inquiry. Please email the Flow Group at flow@dwyeromega.com and can provide an updated manual with the information requested.

Does this meter come with a calibraiton certificate?
Thank you for your inquiry. Unfortunately, there is no option for a calibration cert for these rotameters.
