VFF Rotary Meters

 

Introduction

 

Accurate Low-Flow Metering

 

The Viscous Fluid Flowmeter Series VFF was introduced in 1986 and has successfully metered viscous fluids such as oils, hydraulic fluids, additives, paints, polymers, chemicals etc. Meter bodies are produced in 316 stainless steel offering good chemical and environmental resistance. For tougher applications titanium, super duplex and Inconel are offered.

Applications for flowrates 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 flowrange. The smallest standard stock size offers 0 to 0.7 l/min and the largest up to 270 l/min. Higher flowrate meters can be provided to special order.

An extensive range of meter construction offers pressure ratings to 50 bar suitable for most industrial applications and higher pressure rating designs are manufactured up to 4000 bar.
