This paper presents a cost-effective sensor design based on an arrangement of light dependent resistors (LDRs) to determine the particle flow velocity and the particle concentration of granular material flow. The sensor is designed for both dense phase and dilute phase flow and can be applied wherever a transparent sightglass is used in material conveying. The measurement setup and its applicability for industrial conveying processes are discussed and measurement results utilising plastic pellets are presented.
