Truck platform scales measure load weight.

Anybody who’s ever sold anything to the government knows that the paper trail is as important as the item or service being sold.  It can be a little frustrating, but the system is in place to ensure that transactions are fair and honest, and taxpayers get value for their money.  A case in point is the Iowa Department of Transportation’s procedure for inspecting weighable quantities of purchased materials.  The procedure describes how to use and verify platform scales, and also “weigh hoppers, batch scales, and load cells” as long as they are “checked for accuracy against truck platform scales.”
