Plastic flowmeters

DESCRIPTION

The Visi–Float® flowmeter

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 ±5% of full scale for VFA models, ±3% for VFB. Scales average 2" long on the VFA models, 4" long on VFB.

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. 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 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.
