A sensor is provided along a product passage between the meter and the distribution system. The sensor has a plurality of receivers, each receiver only covering a small portion of the product passage whereby the resolution of the sensor is increased to be able to detect relatively small particles. For certain small particles or low rate application, the sensor counts individual particles to 10 determine the application rate. For larger particles or high application rates, the sensor measures an output signal attenuation to determine the application rate. A controller then vares the meter drive to produce the desired application rate. 162/6 8282Speed Signal 80 Controller 84 Input -86 92 Feed Rate Processor 90 Controller 94 58 52 24 10 7 1(2 14 4 58 36 10 40502 76 4 4478 60 34 110 Fig. 2
