Product Description
Low-Flow Acrylic Flowmeter for Laboratory & Analyzer Systems
The Series VF Visi-Float® Acrylic Flowmeter – Model VFA-32-BV is a precision, direct-reading instrument engineered for accurate low-flow measurement of air, water, and compatible gases or liquids.
Featuring a 6–50 cc/min water range, 2-inch scale, and an integrated brass metering valve, this compact meter is ideal for applications requiring fine manual flow control and continuous visual verification.
Manufactured from solid clear acrylic and backed by over six decades of machining expertise, the Visi-Float series is trusted in analytical, medical, and industrial monitoring environments where stability and repeatability matter.
Designed for Visibility, Control & Repeatability
This model delivers dependable performance in low-flow systems thanks to:
• precision-machined tapered bore for repeatable readings
• hot-stamped direct-reading scale — no conversion charts
• white background for improved float visibility
• solid acrylic body for full visual inspection
• integrated brass needle valve for manual adjustment
• vertical mounting orientation for accurate operation
