Level control is an increasingly important issue for a variety of industries involved in the production, processing, or packaging of liquids or bulk solids, such as the citrus industry. The growing importance of level control is driven by several factors. First, many companies simply have not had adequate methods of level control, relying on rough measurements of inflow and outflow, or purely manual methods. These companies have been ‘flying blind’ and unable to accurately ascertain their inventory conditions, resulting in a host of operational problems. As these companies invest in automated systems, level is one of many inputs that need to be properly monitored. Second, more companies are seeking to manage and reduce their inventory levels in order to reduce both the capital and tax costs of inventory holding.
