Abstract: A flow monitoring system for a particulate feeder having first and second metering devices that meter particulate material from first and second bins, respectively, to a material flow tube, includes a first sensor supported and configured to generate a first flow signal in response to the absence of particulate material within the first metering device; a second sensor supported and configured to generate a second flow signal in response to the absence of particulate material within the second metering device; a third sensor supported adjacent the first bin and configured to generate a first fill signal indicating a level of particulate material within the first bin; a fourth sensor configured to generate a second fill signal indicating the level of particulate material within the second bin; a controller coupled to a first, second, third and fourth sensors and configured to generate a first alarm signal in response to receiving the first flow signal and a second alarm signal in response to receiving a second
