Positive displacement flow-meter LITRE METER

Chemical injection fluids are normally viscous and are therefore natural applications for the VFF meter. The flowrates are relatively low and the pressure is high compared to most general industrial applications. The VFF Rotary meter is the ideal measuring element for these service requirements. Long term stability of metering and reliability is assured by the basic simplicity of design and quality of production.

VFF Meter Design & Advantages

The heart of the VFF meter is a simple but precisely made, oscillating rotor that sits freely within the rotor chamber of the meter. It is manufactured in a variety of materials. The meter principle is of 'positive displacement'. The rotor is driven 'positively' by the flow, which passes through the flowmeter in 'discrete pockets' with minimum fluid 'slippage'. This gives inherently greater accuracy than is available from axial flow turbine type meters for a low flow of a fluid more viscous than water. Each meter provides a exceptionally wide flowrange and has excellent low flow metering capability.
