All rights reserved, Design Right protected V270.docx VFF V270 Model: VFF/V270/SS/40 bar VFF Rotary Piston Positive Displacement Flowmeter Body: 40bar (600 psi) body provided in 316 stainless steel with 2” NPT female process connections in-line. Higher pressure versions available with connections to suit including wafer fitting between ANSI flanges and Grayloc hubs. Alternate materials are available such as titanium, duplex, super duplex and 17-4PH steel. Rotor: The rotor is provided in either anti galling stainless steel (AG, Nitronic 60), Brass (B) or Carbon graphite (C), with a 316SS encapsulated magnet depending on the application. Part code becomes VFF/V270/SS/40/AG etc. Seal: There is a single FPM O-ring seal between the top cap and body. Other elastomers are available e.g. Kalrez®, FEP covered silicon and in higher pressure versions PTFE and Inconel. Pick-up/Transmitter: There is one reed switch installed in a SS housing which is O-sealed to the meter body providing a rating of IP68. The optional Ex ia or Ex d display is mounted on the housing. Typical reed switch life is 30 years at continuous maximum operating flow rate. Pressure rating: 40, 207, 414, 690 and 1035 bar. (600, 3000, 6000, 10000 and 15000 psi). Part code becomes VFF/V270/SS/690 etc. Temperature rating: -40°C to +150°C (subject to chemical compatibility, pressure rating and location of the display), higher temperature sensor available. Pulse output: The unit provides a reed switch output with 1.2 pulses per litre (4.5 pp USG). Viscosity range: 0.8 to 2000 cSt or greater. The normal meter maximum flow rate applies for viscosities from 1.2 to 30 cSt. For higher viscosities up to 2000 cSt a reduced maximum flow rate may apply. Flow rate range: - Normal flow rate range 0-16500l/hr (0-270 l/min, 4300 USG/hr, 102000 USGPD). Minimum flow rate repeatably measured relates to application viscosity and rotor type; for example less than 1500 l/hr for 11 cSt. Consult Litre Meter for rangeability at specific viscosities with specific rotor materials. - 50% over-range capability available for some applications – Please consult Litre Meter. Filtration: A 100 micron filter is advisable for 100% long life serviceability. If filtration is not possible, consult Litre Meter. Accuracy: A calibration certificate is provided based on a representative viscosity fluid for the application. The calibration certificate confirms the flowmeter accuracy. Improved system accuracy can be provided typically to ±1% of actual reading where the linearisation signal processing facility of the display instrument is employed. Optional Display, remote or head mounted: Display of rate and total, battery, loop powered, 24 Vdc, 110 Vac, 240 Vac, optional flow alarms. GRP or Aluminium. Exia display of rate and total , battery or loop-powered, optional flow alarms, ATEX. GRP or coated aluminium. Exd display of rate and total (as shown), 24Vdc, 3 or 4 wire with Optional HART, MODBUS or Fieldbus comms. ATEX or UL. Coated aluminium or stainless.
