VFF Rotary Piston Positive displacement fl owmeters

The Viscous Fluid Flowmeter Series (VFF) has successfully metered viscous fl uids such as oils, hydraulic fl uids, additives, paints, polymers, chemicals etc. Meter bodies are produced in 316 stainless steel which offers good chemical and environmental resistance. For tougher applications titanium, super duplex and Inconel are offered. Applications for fl ow-rates as low 0.00016 litre/min (0.23 litres/day) have been metered within the off- shore oil industry. The meters exhibit exceptional rangeability with a turndown of 3000:1 achieved for just moderately viscous engine oil. The rotor size determines the meter fl ow-range. The smallest standard stock size offers up to 0.7L/min and the largest up to 270 L/min. Higher fl ow-rate meters can be provided to special order. An extensive range of meter construction offers pressure ratings from 0 to 50 bar suitable for most industrial applications and higher pressure rating designs are manufactured up to 4000 bar.
