Abstract: The metering assembly for metering and dispensing non-solid material includes a metering cylinder, an air cylinder, and an air actuator. The metering cylinder has a metering body with a bore and an inlet/outlet port which is in communication with the bore. The metering cylinder includes a displacement rod which has a first end positioned in the bore and an opposed second end. The displacement rod has a first position where the first end of the rod is adjacent to the bottom of the bore and a second position where the first end is spaced from the bottom of the bore. The displacement rod moves between the first and second positions with movement from the first position toward the second position defined as movement in a filling direction and movement from the second position toward the first position defined as movement in a dispensing direction. The metering cylinder also includes a seal for sealing the rod to the bore.
