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.

Visi-Float® Series Flowmeters are available from Amron in a broad selection of flow ranges and direct reading scales for air, gas or water.
Visi-Float® Acrylic Flow meters are exceptionally tough. They are designed for use at pressures up to 100 PSI and temperatures up to 150°F. Do not exceed these limits! Flowmeters should not be exposed to strong chlorine atmospheres or solvents that may be destructive to the acrylic body.
Visi-Float® Flow meters must be mounted in a vertical position with the inlet connection at the bottom and outlet at the top. They can be mounted to a panel, in front of a panel supported by piping only, or mounted directly in rigid piping.
The Series VF Visi-Float® Acrylic Flowmeter is a line of direct reading, precision machined, clear acrylic body flowmeters suitable for both gas and liquid applications. The fabrication of the Visi-Float® flowmeter is backed by over 60 years of experience in acrylic instrument machining. This series consists of 2 in. (51 mm) and 4 in. (102 mm) scales with optional precision metering valves.
What is the maximum supply pressure I can use with the Visi-Float® Flowmeter?
Can I mount my Visi-Float® Flowmeter in any other position than vertical?
No, the flowmeter must be mounted in the vertical position.
