Dwyer Instruments VFB series flowmeters feature a 4 Inch scale and easy to read design. The direct reading scales eliminate troublesome conversions. Integral flow guides stabilise the float throughout the range. The float is highly visible against a white background. The VFB series are accurate within ±3% of full-scale reading.Easy to read design. 4 Inch Scale. Simple installation.
