Product Description
Low-Range Air Flowmeter with Stainless Steel End Connections
The Series VF Visi-Float® Acrylic Flowmeter – Model VFA-3-EC-SS is a precision low-flow air rotameter engineered for laboratory panels, gas analyzer systems, and sampling skids where corrosion-resistant inlet and outlet fittings are required.
With a 0.6–5 SCFH air range and compact 2-inch scale, this configuration provides stable flow indication in sensitive gas circuits while protecting threaded connections from wear, chemical exposure, and repeated service cycles.
By upgrading the end connections to stainless steel, the VFA-3-EC-SS is ideal for facilities handling specialty gases or operating in humid or corrosive environments — without changing the proven acrylic measurement tube that makes Visi-Float meters easy to read at a glance.
