Dwyer, VFB-51D-EC-SS, Series VFB Visi-Float Flowmeter, 4" Scale, 2-20 SCFH & 0.5-9.5 LPM Air, End Connections, SM Wetted Parts
The Visi-Float® flowmeter - bodies are cut and precision machined from solid, clear acrylic plastic blocks. This construction not only produces a handsome finished product, but permits complete visual inspection. As a result, the Visi-Float® flowmeters are especially popular for medical and laboratory equipment applications.
Scales are easy to read - The front scale location and white background provides excellent visibility. The direct reading scales are hot stamped into the plastic and will not wear off. Mid-range calibration is established with a master flowmeter. Accuracy is ±3% of full scale. Scales average 4".
Durable and attractive construction - The machined acrylic bodies of the Visi-Float® flowmeters are practically unbreakable. Fabrication is backed by over 60 years of experience in acrylic instrument machining. The tapered bore is precision machined to a smooth surface that provides perfect visibility of the indicating float. The VFA and VFB models are available with either brass or stainless steel inlet and outlet connections and are tapped for 1/8" NPT thread. All standard models employ Buna-N o-rings for leak proof operation and are available with either back or end connections for horizontal or vertical piping.
Easy installation - All Visi-Float® flowmeters have metal mounting inserts on rear for panel mounting. They can also be supported directly by system piping.
