Introduction
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
Cost saving:
savings on raw materials in the production process
extended metering range; saves on initial purchasing cost and
service parts inventory
User-friendliness:
no need for external viscosity settings; a single meter model is suitable for
different liquids and various physical conditions
easy customer maintenance because of simplified construction and
few internal parts
Unique product features:
constructed for rough industrial environments
reliable construction with few inner parts
local totaliser and/or pulse transmitter according NAMUR for data processing
material certificates according EN 10204 2.2 and EN 10204 3.1B can be provided
measuring tolerance better than +/- 0.1% depending on model and flow range
reproducibility better than +/- 0.05%
flow range up to 1:100 depending on model and requested accuracy
