Abstract: A monitoring system for the affirmative measurement of feed levels in a bin includes a vertically disposed series of pressure sensors carried on a flexible detector strap releasably mounted at the center of the feed bin. The sensors include radially projecting blades that deflect and actuate in response to the downward flow of material being discharged. The signals from the sensors are routed to a local monitoring site permitting on-site determination of fill level. The signals from plural bins may also be routed to a central monitoring site. The local monitoring site is preferably provided with a programmable logic controller for periodically recording the level of the feed bin. The fill data is remotely retrievable for use in determining resupply needs. The system may also beneficially incorporate a modem communications link with a remote service monitoring site.
