Product Description
0.1–1 SCFH Air Acrylic Flowmeter – Visi-Float® VFA-1-SS with Stainless Wetted Parts
The Series VF Visi-Float® VFA-1-SS Flowmeter provides accurate ultra-low air-flow measurement for laboratory, medical, and analytical systems where corrosion-resistant stainless steel wetted components are required without an integrated metering valve.
Constructed from precision-machined acrylic blocks and featuring hot-stamped direct-reading scales, this compact rotameter delivers reliable monitoring, repeatable readings, and clear visual verification in panel-mounted installations.
