Product Description
10–100 LPM Air Acrylic Flowmeter – Visi-Float® VFA-27 (No Valve)
The Series VF Visi-Float® VFA-27 Flowmeter is a compact, direct-reading acrylic instrument designed for air-flow indication in laboratory, medical, and industrial systems where external valves handle regulation. Precision-machined from solid clear acrylic, this model delivers dependable repeatability and full visual inspection of the flow path.
Hot-stamped scales, a white float background, and a tapered-bore measuring chamber provide long service life and easy field readability without electronics or power requirements.
