AFD2

The AFD2 series is a water flow sensor based on the von Karman vortex street principle. When a fluid with a certain volume flow rate bypasses the spoiler column under certain conditions, double-row line vortices with opposite rotation directions and regular arrangement will be periodically formed on both sides of the spoiler column. After nonlinear action, a Karman vortex street is formed. The frequency of vortex formation is proportional to the flow rate. The sensor detects these vortices to measure the flow rate of the fluid in the pipeline.

The sensor has no moving parts inside, and has the characteristics of long service life, pollution resistance, high precision and no drift, which can ensure long-term use by users. It is an ideal choice for OEM applications with high requirements for product performance and strict cost control.
