1. An implement for applying an input product to an agricultural field at variable rates between frame sections, the implement comprising:
- a frame including a plurality of designated frame sections;
a plurality of product dispensers supported on the frame, each product dispenser of the plurality of product dispensers associated with a respective designated frame section of the plurality of designated frame sections;
a product supply arranged to store the input product, the product supply in communication with the plurality of product dispensers;
a plurality of conveying lines, each of the respective conveying lines of the plurality of conveying lines communicating between the product supply and respective product dispensers of the plurality of product dispensers;
a plurality of metering pumps, each of the metering pumps in communication with the product supply and the respective conveying line of the plurality of conveying lines, and each metering pump is associated with the respective designated frame section of the plurality of designated frame sections;
at least two metering devices located downstream of at least one metering pump of the plurality of metering pumps, each metering device in communication with a respective conveying line of the plurality of conveying lines, wherein each metering device includes an adjustable device flow rate independently adjustable from the other metering devices, the device flow rate is adjustable to dispense input product from the product supply to the respective conveying line and designated frame section at a variable rate with respect to the other metering devices; and
each metering pump includes an adjustable set point flow rate independently adjustable from the other metering pumps, wherein each set point is adjustable to dispense input product from the product supply to the respective conveying line and respective designated frame section at a variable rate with respect to the other metering pumps.

Abstract
Metering devices for an agricultural implement are provided for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.
