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.

Features
  • 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

Principle Measurement
When a columnar object ( object that generates vortices) is placed in the flow path a of a fluid, regulecalled karman vortex channels, are generated at the back of the object. Since the frequency of a vortex generated is linearly proportional to the flow velocity within a given range, the flow amount can be measured by counting the number of vortices.

These series models make use of the principle. When the frequency of each vortex generated is detected by incorporated vortex detector (piezoelectric device), the signal processing circuit outputs a signal which is linearly propotional to volume flow.
