Scales are easy to read - The front scale location and white background provides excellent visibility.
Mid-range calibration is established with a master flowmeter.
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.
Available with either brass or stainless steel inlet and outlet connections and are tapped for 1/8" NPT thread.
VFB models 85 and 86 have either 1/4" back or 3/8" end connections.
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.
Precision metering valves in brass or stainless steel are available for most VFA and VFB models.
Easy installation - All Visi–Float® flowmeters have metal mounting inserts on rear for panel mounting. They can also be supported directly by system piping.
