Product Description
0.1–1 SCFH Air Acrylic Flowmeter – Visi-Float® VFA-1 Indicator-Only Model
The Series VF Visi-Float® VFA-1 Flowmeter is engineered for ultra-low airflow measurement in laboratory, analytical, and OEM systems that utilize external flow-control valves.
This acrylic rotameter provides a direct-reading SCFH scale, a precision-machined tapered bore, and a compact 2-inch scale length — ideal for tight panel assemblies and instrumentation racks requiring repeatable micro-flow monitoring without onboard regulation.
