Product Description
6–50 LPM Air Acrylic Flowmeter with Brass Valve – Visi-Float® VFA-26-BV
The Series VF Visi-Float® VFA-26-BV Flowmeter combines accurate visual flow indication with an integrated brass precision metering valve for manual air-flow control in laboratory, medical, and industrial process systems. Machined from solid clear acrylic and engineered for repeatable performance, this model is ideal where operators need to both monitor and regulate low-range gas flow from a single compact instrument.
Hot-stamped direct-reading scales, a white float background, and a precision-tapered bore deliver long service life and easy readability without electronics or power requirements.
