Dwyer Visi-Float® Flowmeters Series VFC & VFCII
Used to Indicate Air or Water Flow
The accurate and durable VFC Visi-Float® flowmeter contains a stainless
steel guide rod and large diameter float for excellent stability and visibility in
high flow rates. The large 5˝ scale provides a ±2% full scale accuracy for
precision measurement required in medical or laboratory applications. The
VFC models have PVC 1˝ female NPT connections. VFC II units are equipped
with acetal thermoplastic 1˝ male NPT fittings. VFC II fittings also include
hex wrench flats to prevent stripped threads. All models have metal mounting
inserts on the back for panel mounting. Units may also be supported directly by
system piping.
