Product Description
Low-Range Air Flowmeter with Stainless Wetted Components
The Series VF Visi-Float® Acrylic Flowmeter – Model VFA-3-SS is a precision low-flow air rotameter engineered for analyzer panels, laboratory benches, and sampling systems that require enhanced chemical compatibility without an integrated control valve.
With a 0.6–5 SCFH air range and compact 2-inch scale, this model delivers dependable measurement in gas-monitoring applications where corrosion resistance and stable long-term performance are essential.
By upgrading the wetted metallic components to stainless steel, the VFA-3-SS is ideal for environments handling specialty gases, trace contaminants, or aggressive carrier streams while maintaining the Visi-Float platform’s proven acrylic visibility and repeatability.
