DWYER Flowmeter - Series VFA & VFB ( Visi-Float® FLowmeters )
Used to indicate or Monually Control Air or Water Flow
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® floemeters are especially popular for medical and laboratary 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.
