Low Flow Magmeter - Discontinued

FMG80 Series

 | FMG80 Series

See All Models Below

  • No Moving Parts
  • Requires No Straight Pipe
  • Pulse and/or 4 to 20 mA Output
  • Chemical and Corrosion Resistant
  • Insensitive to Fluid Density and Fluid Viscosity Changes
  • NEMA 4X (IP66)


The FMG80 series has been discontinued. Please see the FMG80A Series as a possible alternative or contact our Flow Engineering department.

The FMG80 Series magmeter is designed for low-flow chemical injection or difficult-to-meter applications with pulsating metering pumps in ¾ to ¼" pipe/tube. The housing is made of sturdy splashproof HDPE plastic.

With no moving parts, the FMG80 Series can handle fluids containing particulate matter without clogging or jamming, keeping maintenance at a minimum. With no metallic parts (100% PVDF body and PVDF carbon fiber-filled electrodes), the meter is corrosion-resistant and compatible with a wide range of chemicals. Accuracy is maintained with conductive fluids (>20 micro Siemens) of varying viscosities and densities.

The FMG80 Series meter is compact enough to fit most pump/injection systems. With zero straight pipe required after an elbow, it can be easily mounted in tight spaces. The mounting bracket adds stability.

The FMG80 Series meter has opto-coupled current sinking or current sourcing pulse as well as a 4 to 20 mA output that can be connected to many OMEGAR panel meters, controllers and data loggers; outputs and power are provided through a 6 m (18') cable with 8-pin female circular connector.
