Small Karman Vortex Flow Meter for Liquids
FM0101 / 0102 / 0103 / 0105 SeriesKOFLOC'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
- Measurement 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 and chemicals (The sensor is acid-/alkali-resistant).
- These models are in the process of application for CE Marking
Standard Specifications
Principle of Measurement
When a columnar object (object that generates vortices) is placed in the flow path of fluid, regular channels of vortices, called 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 rangem the flow amount can be measured by counting the number of vortices.These series models make use of this principle. When the frequency of each vortex generated is detected by the incorporated vortex detector (piezoelectric device), the signal processing circuit outputs a signal which is linearly proportional to volume flow.
