Small Vortex Flow Meter For Liquids kofloc

Kofloc Small Karman Vortex Flow Meter For Liquids FM0101/0102/0103/0105 SERIES

KOFLOC’s Karman Vortex Flow Meter FM Series provides an ideal tool for measuring and monitoring liquid flows, including cooling water and cleaning water. Since PPS resin is used for body material,all models of the series offer superior reliability and durability.


  • Simple design that minimizes a dead space

  • Measurements of very small flows available (up to 0.5 L/min)

  • Use of PPS resin has achieved a small,lightweight and rigid

  • The sensor can be used for pure water or deionyzed water or deionyzed water and chemicals (the sensor is acid-/alkali-resistant).

  • These models are in the process of aplication for CE Marking
