Category: Tag:


Dwyer Flow Measurement Instruments are suitable for liquids and
gases in a variety of applications including HVAC, building automation, process
control industries, water, wastewater, food and beverage and pharmaceutical and
general manufacturing markets.


  • The SERIES VF Visi-Float Flowmeters are a line
    of direct reading, precision machined, clear acrylic body flowmeters suitable
    for both gas and liquid applications. The fabrication of the Visi-Float
    Flowmeters is backed by over 60 years of experience in acrylic instrument
    machining. This Series consists of 2 (51 mm) and 4 (102 mm) scales with
    optional precision metering valves.
  • The SERIES V4 Flotect Flow Switches is rugged
    and reliable, ideal for automatically protecting equipment and pipeline systems
    against damage from reduction or loss of flow. Time tested in thousands of
    pipeline installations and processing plants around the world this Series is
    Weatherproof, designed to meet NEMA 4 and Explosion-proof (listing included in
    specifications). This series can be used in pipes 1-1/2 (38.10 mm) and up.
  • The SERIES FS-2 Vane Flow Switches offers an
    economical flow proving solution. The FS-2 paddles are adjustable to fit 1 to
    8 size pipe.
  • The SERIES PFT Insertion Paddlewheel Flowmeters are
    used to monitor liquid flow rates in pipes from 1-1/2 to 40 and is available
    in brass or 316 SS body. The unit outputs a frequency proportional pulsed or 4
    to 20 mA output. The pulse models are a square wave output signal with
    frequency proportional to the flow velocity and the 4 to 20 mA models have a
    linear output of the velocity with 4 mA equal to 0 ft/s and 20 mA equal to 25
  • The SERIES WMT2 Multi-Jet Water Meters is a
    series of mechanical, water totalising meters that display the total water
    usage in gallons or m3 and provide a reed switch output proportional to flow
    rate. They are available in a range of body sizes and include NPT or BSPT
