Designed to weigh up a continuous flow of product for inventory purposes.  There are thousands of ways we can write software for this but here is just one example:As product is coming into the plant it runs through this machine.  It weighs it into, for example, 500 pound weighments, records the weight and discharges it back into the line.As it interrupts the flow of material, it is diverted into a catch chamber that allows product to continue moving.The machine automatically continues this process.  It can be programmed to record and compile data on demand, by the hour, by the day or by the month.  This data can then be transferred to your plant’s computer where it can be stored and retreived in any number of report configurations, charts, graphs, etc.Request additional info.
