Size VFF4

The VFF is a range of reliable flow meters offering accurate flow measurement, maintenance requirement and a very high specification. Supplied as standard with a head-mounted FlowPod display.

Accurate over a wide flow range

VFF meters are accurate to within ±1% of reading over their wide operating range and are repeatable to ±0.1% of reading.

Reliable, single moving part design

Proven in service since 1985, over 5,000 VFFs are installed in arduous conditions, worldwide.

User-friendly display, analogue output & HART communications

Everything you need supplied as standard:

  • Rate and total including legends showing units chosen.
  • 4-20mA output
  • 2 wire
  • HART communications
  • Hazardous Area certified
  • IP66/IP68 Stainless steel housing

VFF8 Base Model Configuration details

VFF8 4.8 to 800 l/hr, on standard 15cP calibration

  • 316L Rotary Piston VFF Flowmeter, PBC type. Pressure rating 530 bar.
  • Nitronic 60 Rotor and Chamber with ultra low friction PVD coating
  • Viton O’ring Seals
  • 1/2 inch female NPT
  • Direct mounted FlowPod display

Complete with:

  • Exd certification
  • Material Test Certificates
  • Hydrostatic Certificate and
  • Calibration Certificates

The O-ring seals can be specified as Viton, Nitrile, EPDM or PTFE Encapsulated Viton at no extra cost.

Other materials such as Chemraz and Kalrez cost extra but are available on the same swift lead time. Calibration can be customised according to the customer’s requirement at extra cost, same lead-time.
