Product Description
Precision Low-Flow Air Measurement for Analytical & Process Systems
The Series VF Visi-Float® Acrylic Flowmeter with Brass Valve (VFA-3-BV) delivers highly repeatable low-flow air measurement and control for laboratory instruments, gas analyzers, sampling systems, and purge air applications. Designed for technicians who demand visual confirmation and stable regulation, this panel-mount air rotameter combines a crystal-clear acrylic body with a fine-adjust brass metering valve for dependable, field-adjustable flow tuning.
Built from decades of acrylic machining expertise, the Visi-Float platform offers direct-reading scales, precision-tapered bores, and rugged wetted components—making it a trusted solution for research facilities, environmental monitoring stations, OEM assemblies, and industrial process panels.
