Kofloc FM01 Vortex Flow Meter for Liquids

KOFLOC’s Karman Vortex Flow Meter FM Series provides an ideal tool for measuring and monitoring liquid flows, in-cluding cooling water and cleaning water.

Kofloc FM01 Vortex Flow Meter for Liquids 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 the body material, all models of the series offer superior reliability and durability.

When an object is put in a flow of liquid, an oscillating vortex street, called Karman vortex street, takes place in downstream of the object. It was named after the fluid dynamicist who discovered this phenomenon. Our Karman vortex flow meters have been developed based on the measurement principle of a Karman vortex street.

Small and lightweight.
Wide flow range available from 0.5~4L/MIN to 10~150L/MIN.
