The Dwyer Instruments Series VF Flowmeters 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.

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 ±15% of full-scale for VFA models, ±13% for VFB. Scales average 2" long on the VFA models, 4" long on VFB.
