Abstract
This document discusses, among other things, apparatus and methods for a multi-section applicator having variable-rate sections. In an example, an apparatus can include at least one distribution manifold, a user interface, and an applicator controller. The at least one distribution manifold distributes a substance and can include an inlet port configured to receive the substance, a plurality of outlet ports, one or more sensors located at an outlet port, a controllable valve that supplies the substance to the inlet port. The applicator controller measures a value of the distribution parameter using the sensor signal produced by the at least one sensor of an outlet port, detects when the measured value differs from a specified target value by more than a specified error threshold value, and presents an indication, using the user interface, that the measured value differs from the target value according to the detection.
