Abstract: A device for measuring a volume of flowable material and may be used for transporting dewatered biosolids over relatively short distances through a pipe. The device includes a screw conveyor including a conveyor housing, and a conveyor screw rotatably supported in the conveyor housing and operable to move flowable material through a housing outlet, and an electromagnetic flow meter operable to measure the volume of flowable material flowing from the housing outlet. The conveyor housing may include a generally cylindrical first portion and a tapered, generally frusto-conical second portion adjacent the housing outlet. The device may include a flap assembly supported adjacent the outlet of the flow meter. The device may include a pipe arrangement on the discharge of the flow meter.
