Abstract
A volumetric metering system includes a housing configured to be coupled to a commodity container. The housing has a transducer portion. A roller is removably coupled within the housing and has an encoding tab with at least one circuit. The encoding tab is positioned to allow interaction between the circuit and the transducer portion when the roller is installed in the housing. A controller is operably coupled to the transducer portion and configured to cause the transducer portion to interact with the circuit and identify the roller based on the interaction. The controller is configured to automatically set roller information based on automatic identification of the roller. In one example, the roller is provided with a set of magnets the relative positions of which encode the roller.
