Product Description
Mid-Range Airflow Control for Process & Analyzer Systems
The Series VF Visi-Float® VFA-27-SSV Acrylic Flowmeter is engineered for applications that require both visual flow indication and precise manual airflow regulation in the 10–100 LPM range. Equipped with an integrated stainless steel metering valve, this model allows operators to fine-tune air delivery directly at the instrument—eliminating the need for separate upstream regulators in many installations.
Built from optically clear acrylic and precision-machined with a tapered bore, the VFA-27-SSV delivers fast, stable readings while maintaining excellent repeatability in laboratory panels, analyzer cabinets, cabinet purge circuits, and industrial air systems.
