Product Description
Low-Flow Acrylic Flowmeter for Systems Using External Control Valves
The Series VF Visi-Float® Acrylic Flowmeter – Model VFA-32 is a precision low-flow measurement instrument engineered for laboratory, analyzer, and process-monitoring systems where flow control is handled externally.
With a 6–50 cc/min water range and compact 2-inch direct-reading scale, this no-valve configuration is ideal for panel-mounted installations that rely on upstream regulators or needle valves while still requiring continuous visual flow verification.
Machined from solid clear acrylic and supported by decades of instrument-manufacturing experience, the Visi-Float platform delivers repeatable readings in demanding analytical and industrial environments.
Engineered for Accuracy, Visibility & Repeatability
This model provides dependable performance thanks to:
• precision-machined tapered bore
• hot-stamped direct-reading scale
• white contrast background for fast reading
• solid acrylic body for full visual inspection
• vertical mounting for proper operation
• compact footprint for analyzer panels
Typical Applications
• gas analyzers
• laboratory benches
• air samplers
• pollution monitors
• cabinet purge systems
• chemical injection lines
• medical equipment
• research instrumentation
