Series VF VISI-Float Acrylic Flowmeter
Brand: Dwyer Instruments, LLC
The Series VF Visi-Float® Flowmeters are a line of direct reading, precision machined, clear acrylic body flowmeters suitable for both gas and liquid applications.
The fabrication of the Visi-Float® flowmeters is backed by over 60 years of experience in acrylic instrument machining.
This Series consists of 2" (51 mm) and 4" (102 mm) scales with optional precision metering valves.
Features- Bodies are cut and precision machined from solid, clear acrylic blocks allowing for complete visual inspection
- White background allows for better visibility of the float 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 with metal mounting inserts that can be supported directly by system piping
