1. An agricultural machine comprising:
a metering system comprising one or more meters configured to meter particulate material into a first material distribution line and a second material distribution line;
a first sensor configured to generate a first sensor signal indicative of a first pleasure of a flow of the particulate material in the first material distribution line;
a second sensor configured to generate a second sensor signal indicative of a second measure of the flow of the particulate material in the first material distribution line; and
a control system configured to:
receive an indication of a sensed flow rate of the particulate material in the second material distribution line;
obtain an adjusted flow rate indication by applying, to the sensed flow rate, a rate offset based on the first and second sensor signals; and
control the metering system based on the adjusted flow rate indication.
