Abstract
A metering system is driven by a transmission for metering product from a product tank. The metering system has a meter housing, within which is mounted a meter cartridge having an inlet releasably coupled to the product tank. A meter roller which has an axial bore is rotatably mounted in the meter cartridge. A drive shaft extends through the axial bore of the meter roller for rotating the roller with the drive shaft. A meter drive is fixed to an end of the drive shaft against rotation relative to the drive shaft. The meter cartridge has an engaged position wherein the meter cartridge is mounted in the meter housing and the meter drive is engaged by the transmission for rotating the meter roller, as well as a disengaged position where the meter drive is not engaged by the transmission for allowing the meter cartridge to be removed from the meter housing and for allowing the inlet of the casing section to be at least partially uncoupled from the product tank.
