Since 1989, FGIS has been encouraging export elevators to install automated systems to monitor grain flow paths, maintain weight records, and activate alarms and shut-down devices, if necessary. Such systems can monitor flow paths more diligently than humans and are less likely to record erroneous weights. In addition, they can prompt personnel to perform scale checks and reduce the need for inspection personnel to visit sites inside the elevator. As entering the elevator always involves some risk, an automated system improves safety. The elevator benefits because a properly functioning automation system allows FGIS to operate with a smaller inspection team, and hence charge smaller fees.
The elevator is responsible for contracting for the design and installation of the official automated system because it must be integrated with the elevator's own control system. FGIS advises the elevator and contractors during the development of the system, and carefully checks out the system for security and functionality before approving its use. FGIS assumes control of the automated system after its approval. Repairs and upgrades are made by the elevator's automation contractor, but must be approved beforehand and checked out afterward by FGIS.
Eight export elevators' systems have been approved. Four more automated weighing systems are in development.
