ABSTRACT:
A method and apparatus for metering flowable particulates wherein the particulates are fed at a uniform speed through an array of radiation beams, the interruptions of these beams are used to compute a value representing the total amount of particulates present in the array of beams and this value is totalized with time. This totalized value is used for monitoring the flow of particulates.
