Product Description
10–100 LPM Air Acrylic Flowmeter – Visi-Float® VFA-27-EC
The Series VF Visi-Float® VFA-27-EC Flowmeter is a compact, direct-reading acrylic flow instrument designed to indicate or manually regulate air and liquid flow in laboratory, medical, and industrial systems. Built from solid clear acrylic and precision-machined for repeatable performance, this model features standard nickel-plated brass wetted components and convenient end connections for pipe-supported installation.
Hot-stamped scales, a white float background, and a tapered-bore measuring chamber make the Visi-Float® ideal for real-time process visibility without electronic sensors or power requirements.
