Product Descriptions

The AFD4 series is a vortex street water flow sensor based on the principle of Von Karman vortices. When a fluid with a certain volume flow rate 

passes through a turbulence column under certain conditions, periodic double row line vortices with opposite rotation directions and regular 

arrangement will be formed on both sides of the turbulence column, forming a Karman vortex street. The sensor senses the frequency of vortex 

flow through the internal chip, thereby calculating the liquid flow rate flowing through the pipeline. Sensors have the characteristics of long 

service life, pollution resistance, high precision, fast response, and no drift, making them an ideal choice for demanding and cost sensitive OEM 

applications.

Product  Application

The AFD4 series flow sensor is a commonly used measuring instrument with a sturdy casing and compact structure, providing a multifunctional 

sensing solution for multiple application scenarios such as harsh industrial production environments, energy metering, environmental 

protection, laboratory environments, and transportation.
