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 flow signal and a notification device coupled to the controller and configured to produce a first alarm in response to the first alarm signal and a second alarm in response to the second alarm signal. Preferably, the controller is configured to generate the first visual display based on the first fill signal and the first flow signal to simultaneously indicate the amount of material within the first bin and whether the material within the first bin is bridging. The controller is also preferably configured to generate a second visual display based on the second fill signal and the second flow signal to simultaneously indicate the amount of material within the second bin and whether the material within the second bin is bridging.
