Bin weighing system
A bin monitoring system functions both as a device for lifting the bin and as a weighing system for monitoring or measuring the level of feed or other product in a bin. Various embodiments and methods of retrofitting the bin monitoring system to existing bins are provided. Further, the accuracy provided by various embodiments enables one to accurately predict when the bin will be empty. Thus, a feed mill, for example, can be aware of anticipated needs days in advance, allowing the feed mill to better optimize its scheduling and deliveries.
