Supported Applications
The Omega FL-75 Series consists of industrial variable area flow meters designed for water applications with capacities ranging from 0.5 to 200 GPM. These units feature direct-reading scales and vertical connections intended for easy installation in process lines.
Operating Conditions & Performance
The series operates within a maximum temperature of 130° and a maximum pressure rating of 150 psi. Accuracy varies by model configuration, with documented values including "3/1 % FS", "6/2 % FS", and "4/1 % FS" depending on the specific range selected.
Key performance specifications include:
- Scale Length: 127 mm (5") direct reading on tube
- Media Compatibility: Water
- Construction Type: Shatter-resistant, non-glass acrylic metering tubes
Variance by Model Range
The series offers 14 distinct model numbers covering specific flow ranges. Pressure drop requirements increase with capacity, ranging from 10 inH₂O for the FL-75A (0.5 to 5 GPM) up to 80 inH₂O for the FL-75P (55 to 200 GPM).
Wetted Materials
The internal components utilize specific materials suited for water service:
- Metering Tubes: Acrylic
- Floats and Guide Rods: 316 SS
- Float Stops: Polysulfone
- O-Rings: EPR
- End Fittings: PVC
Configuration Options
The FL-75 Series is available in 13 enabled variants, each corresponding to a specific flow range and connection size. The series supports three process connection sizes: 1 NPT, 1½ NPT (male), and 2 NPT.
Model Selection by Connection Size
- 1 NPT: Models FL-75A through FL-75E cover ranges from 0.5 to 30.5 GPM with an overall width (Dimension A) of 51 mm (2 in).
- 1½ NPT (male): Models FL-75F and FL-75G cover ranges up to 50 GPM, maintaining a Dimension A of 51 mm (2 in) but with increased height.
- 2 NPT: Models FL-75J through FL-75P handle higher capacities from 4 to 200 GPM. These units feature an overall width (Dimension A) of 76 mm (3 in).
Calibration Options
The series supports optional calibration certificates. For a 5-point NIST calibration certificate, add the suffix "-NIST 5PT" to the model number; for a 10-point calibration, use the suffix "-NIST 10PT".
Key Product Differences
Differences across the FL-75 Series are defined by flow capacity, accuracy class, and physical dimensions. Models with lower capacities (FL-75A to FL-75E) utilize a "3/1 % FS" accuracy specification, while higher-capacity models such as FL-75F and FL-75G list "6/2 % FS", and the 2 NPT series includes both "4/1 % FS" (FL-75J to FL-75M) and "6/2 % FS" (FL-75N to FL-75P).
Physical dimensions vary by connection size. Models with 1 NPT connections have a height (Dimension B) of 260 mm (10.3 in). The 1½ NPT models increase this dimension to 306 mm (12.1 in), while the larger 2 NPT series units measure 337 mm (13.3 in) in height.
Each unit comes complete with an operator's manual and includes a standard warranty option of "1 YEAR WARRANTY" along with RoHS compliance.
