Pretty much all calculations. At every flow of grain the impact sensor will have a certain output. During calibration we are assigning a known weight to the sensor output. Lets say that after calibration the monitor knows that a 1 millivolt output is equal to 10 pound per second, 2 millivolt is equal to 20, 3 is equal to 40 4 is equal to 60. Going thru the field the flow sensor has a 4 millivolt output. Now the calculations start 4 millivolt is equal to 60 pounds per second. 60 pounds per second times 60 seconds per minute times 60 min per hr is equal to 216000 pounds per hr. We are doing corn so the monitor knows that corn weighs 56 lb per bu. 216000 / 56 is equal to 3857 bu per hr At the time of the sensor reading we were going 4 mph running a 12 row 30" head which is equal to 14.54 acres per hour. Again all calculations. 3857 bu/hr divided by 14.53 acres / hr equals 265 bu per acre. An 1 millivolt output would be 44 bu per acre at the same 4 mph. This may not be exactly how they work but I think the logic is correct. Once the calibration is complete and the monitor knows the calibration curve it is all calculations based on sensor output, calibration curve, speed, head width, and grain type to get the yield per acre
