Small Karman Vortex Flow Meter for Liquids
FM0101/0102/0103/0105 SERIES
|      Features     |     Standard Specification     |    

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. PFA resin can be used instead of PPS,except for Model FM1015 Series,according to the customer's requirement.


  • Simple design that minimizes a dead space
  • Measurements of very small flows available(up to 0.5L/min)
  • Use of PPS resin has achieved a small,lightweight and rigid
  • The sensor can be used for pure water or demineralized water and chemicals(the sensor is acid-/alkali-resistant).
  • These models are in the process of application for CE Marking and CAS.
