In the food industry, grain, corn, wheat, flour and other raw materials are stored in large silos where environmental conditions inside the silos are very dusty.
Very large storage silos contain thousands of tons of inventory every month. Each month assessment of inventory and process control requirements may be off the mark by up to 10,000 tons due to inaccurate or unreliable measurement of silo contents using a single point level measurement device. This uncertainty presents challenges not only to storage and production planning, but to financial forecasting as well.
Raw materials for animal feed are stored in open bins that are emptied according to production demands. As the material is taken out using a tractor, the raw material is formed irregularly in the bins, making accurate inventory measurement nearly impossible.
