Agricultural seed sensing and control system

A method performed by an agricultural machine, the method comprising:

• receiving a first sensor signal from a first sensor, the first sensor signal being indicative of a first measure of a flow of particulate material in a first material distribution line;
• receiving a second sensor signal from a second sensor, the second sensor signal being indicative of a second measure of the flow of the particulate material in the first material distribution line;
• receiving an indication of a sensed flow rate of particulate material in a second material distribution line;
• obtaining an adjusted flow rate indication by applying, to the sensed flow rate, a rate offset based on the first and second sensor signals;
• and
• controlling a metering rate of the particulate material in the second material distribution line based on the adjusted flow rate indication.

A control system for an agricultural machine, the control system comprising:

• at least one processor;
• and
• memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the control system to:
• receive a first sensor signal from a first sensor, the first sensor signal being indicative of a first measure of a flow of particulate material in a first material distribution line;
• receive a second sensor signal from a second sensor, the second sensor signal being indicative of a second measure of the flow of the particulate material in the first material distribution line;
• receive an indication of a sensed flow rate of particulate material in a 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 a metering rate of the particulate material in the second material distribution line based on the adjusted flow rate indication.
