Liquid Flow Meters

VAF Instruments positive displacement liquid flow meters stand for accurate volumetric

measurement of a wide range of liquids, from low-density LPG to viscous chemical and

petroleum products. VAF Instruments liquid flow meters are used in continuous metering

applications, in-line blending processes, metered deliveries as well as for batching

applications, such as the filling of containers and storage tanks. VAF's range of

products covers flow rates from 1 litre/hour up to 960 m3/hour.

Why choose VAF Instruments liquid flow meters?

VAF Instruments flow meters are accurate and reliable. They are approved by 14 independent classification agencies, which is more than any other flow meter can boost on. Specific models are suitable for operating pressures up to 320 bar and a standard choice of high quality materials cover almost every service condition.

User benefits

Product quality:

blending and batching system accuracy

 consistent end-product quality suitable for a wide viscosity range without affecting the accuracy specified for the measuring range
