Wheat germ, like bran, is a by-product of wheat milling and serves as an additive to different types of baked goods. Following the milling process, it is stored in silos prior to being shipped. Wheat germ is sold and shipped in bulk, and flour manufacturers need to accurately monitor the inventory remaining in the silo to ensure that packing and delivery schedules can be met. Installing additional level switches prevents overfilling that may lead to overspills.
