  • The GF Signet 2537 paddlewheel flow meter is the next generation in fluid measurement technology from the inventor of the original paddlewheel flow meter. The 2537 Flow Meter is an improvement on what’s already an industry standard. It has the added functionality of various output options including flow switch, multi-functional pulse divider, digital (S³L), or 4 to 20mA. Additionally, the GF Signet 2537 paddlewheel flow meter offers low flow, low power, and high resolution and can be configured onsite directly through the built-in user interface.Installation is simple because the GF Signet 2537 paddlewheel flow meter utilizes the same fittings as the popular GF Signet 515 and 2536 paddlewheel sensors and fits into pipe sizes ranging from DN15 to DN200 (0.5 to 8 inches). Available in Polypropylene and PVDF, the GF Signet 2537 paddlewheel flow meter is ideal for a variety of applications including chemical processing, water, and wastewater monitoring scrubber control.
  • GF Signet 2537 Paddlewheel Flow Meter Applications:

  • Process flow monitoring
  • Pump protection
  • Pure water production
  • Filtration systems
  • Chemical production
  • Reverse osmosis
  • Demineralization / regeneration
  • Fume scrubbers
  • Cooling towers
  • Proportional metering pump
