Product Description
0.2–2 SCFH Air Acrylic Flowmeter – Visi-Float® VFA-2-EC with End Connections
The Series VF Visi-Float® VFA-2-EC Flowmeter is designed for low-range SCFH airflow indication in laboratory, medical, and industrial systems that use external flow-control valves and require a compact end-connection mounting configuration.
Machined from solid clear acrylic with a hot-stamped direct-reading scale, this rotameter delivers dependable repeatability, rapid visual confirmation, and long service life in tight piping layouts.
