Product Description
Low-Flow Air Rotameter with Stainless Steel Control Valve
The Series VF Visi-Float® Acrylic Flowmeter – Model VFA-3-SSV is a precision low-range air flowmeter engineered for analytical panels, laboratory benches, and sampling systems that require fine manual control and corrosion-resistant valve construction.
With a 0.6–5 SCFH air range, compact 2-inch scale, and integrated stainless-steel metering valve, this model excels in gas-monitoring applications where stable flow adjustment and visual confirmation are critical.
Machined from solid acrylic and backed by decades of flow-instrument expertise, the Visi-Float platform delivers consistent performance in both research and industrial environments.
Designed for Gas Control & Analyzer Panels
This configuration provides:
• stainless-steel needle valve for chemical compatibility
• ultra-low air-flow measurement capability
• precision-machined tapered bore
• direct-reading hot-stamped scale
