Supported Applications
The Omega FL-3600 and FL-3800 Series are precision variable area flow meters designed for measuring the flow of air, water, and gases. The series supports applications involving nitrogen, oxygen, hydrogen, helium, argon, and carbon dioxide; correlation data for these specific gases is available by consulting Engineering.
Operating Conditions & Performance
The FL-3600/FL-3800 Series delivers an accuracy of ±2% full scale (±5% FS on * models) with a repeatability of ±0.25% full scale. The meters operate at process temperatures up to 121°C (250°F) and withstand pressures up to 200 psig (13.8 bar). Flow ranges vary by tube size: the 65 mm flowtube covers Air from 5.77 cc/min to 58,500 cc/min and Water from 0.07 cc/min to 1866.0 cc/min; the 150 mm flowtube covers Air from 48.5 cc/min to 59,494 cc/min and Water from 0.53 cc/min to 1881.0 cc/min.
Key performance characteristics include:
- Scales: 65 or 150 mm arbitrary scale with 1 mm (⅜") increments
- Minimum Flow Rate: 10% of the maximum rate shown for each model
- New Flow Rates Effective Date: March 1, 2013
Configuration Options
The series is configurable across frame materials, float types, and valve options to meet specific installation needs. Models are available with aluminum or 316 SS frames.
- Frame Materials: Anodized aluminum (FL-36xx) or 316 Stainless Steel (FL-37xx/FL-39xx)
- Float Types: Glass ('G'), 316 SS ('ST'), Carboly ('C'), and Sapphire ('SA')
- Process Connections: ½ FNPT, horizontal
- Wetted Materials by Frame Type:
- Anodized Aluminum Models: Borosilicate glass flow tube; Polyacetal valve orifice; Buna O-rings and packings.
- 316 SS Models: Borosilicate glass flow tube; Kel-F valve orifice; FKM O-rings and packings.
- Special Options (Suffixes):
- -HRV: 16-turn, high-resolution, non-rising stem valve (for 150 mm models)
- -NV: No valve configuration
- -NIST AIR / -NIST WATER: Optional NIST calibration
- -02CLEAN: Oxygen cleaning service
Key Product Differences
The series distinguishes between two primary flow tube sizes and frame material families. The FL-36xx/FL-37xx models utilize 65 mm flow tubes, while the FL-38xx/FL-39xx models utilize 150 mm flow tubes.
- Frame Designation: Models beginning with '36' feature an aluminum frame; models beginning with '37', '38', or '39' feature a 316 SS frame. The second digit indicates the tube size (e.g., FL-36xx/FL-37xx are 65 mm; FL-38xx/FL-39xx are 150 mm).
- Float Material: Suffixes 'G', 'ST', 'C', and 'SA' denote glass, stainless steel, carboly, and sapphire floats respectively.
- Housing Dimensions (Center to Center): 131 mm (5.156") for the 65 mm size; 240 mm (9.469") for the 150 mm size.
- Valve Orifice Material: Polyacetal is used in aluminum models, while Kel-F is specified for 316 SS models.

A sturdy flow meter
Was delivered a couple of weeks ago. It's well built. Mounting holes are easy to drill on panels. Attaches well to the panel. Documentation is poor. The spec sheet is online, but there is a flow data sheet that comes with the unit. If all this is together in one place, it'd help the user a lot. If the flow data can be downloaded as a spreadsheet, it'd be a lot more user-friendly. I'm typing the data into a spreadsheet to use in my lab.

Hi, I was curious about the carboloy float. What is the total volume and cross sectional area for this model. I plan on flowing different gasses and wanted to calculate the corresponding flow rates.
Thank you for your inquiry about the rotameter. The Carboloy float has a density of 14.98 g/mL.

Does the flow meter come with a CoC that certifies it is built to the specifications stated in the datasheet? Will the CoC serve as an initial calibration certificate (not an NIST type)?
Thank you for your inquiry about the rotameter. Yes, a CoC is included with the purchase and can serve as a calibration cert.
