SERIES MW – VARIABLE AREA FLOW RATE INDICATORS

FEATURES/BENEFITS:

  • Direct Reading Flow Rate Indication
  • Optional switch(es)
  • Optional 4-20mA output signal
  • Pressures up to 2000 PSIG (410 Bar)
  • Maximum temperatures to 400oF (315oC)
  • Wafer connection mounts easily between ANSI, JIS or DIN flanges
  • Versatile mounts in any orientation
  • No Straight Pipe Runs Required
  • Easy to read with Dark or Opaque Fluids
  • Full Scale Flow Ranges from 15 GPM (50 LPM) to 5000 GPM (19,000 LPM) 100 SCFM to 50,000 SCFM (depending upon pressure)
  • Connections sizes are from 3-inch to 12-inches

GENERAL DESCRIPTION:

Sure Flow Products variable area flow rate indicators are designed for touch industrial applications.This flow indicator is mechanical with a spring-loaded vane and pointer indicator. This allows for mounting in any orientation and is ideal for use with dark or opaque fluids. The body mounts between flanges which reduces weight, size and cost. Standard with mechanical indication with options of one or two switches, and /or a two wire 4-20mA output signal.
