The Series VFC Visi-Float® Acrylic Flowmeters are direct reading, precision
machined, clear acrylic body owmeters suitable for both gas and liquid applications.
This Series consists of two 5˝ (127 mm) scale owmeters, the VFC and VFC II. The
VFC features PVC 1˝ female NPT connections and the VFC II units are equipped with
acetal thermoplastic 1˝ male NPT ttings.
FEATURES/BENEFITS
• Bodies are cut and precision machined from solid, clear acrylic blocks allowing for
complete visual inspection
• White background allows for better visibility of the oat increasing reading accuracy
• Direct reading scales are hot stamped into the plastic eliminating the need for
troublesome conversions and increasing product operating life
• Precision machined tapered bore enables high repeatability
• Low installation costs with back or end connection options
