Smart Position Indicator (SPI) from Rotork Gears

摘要

Refinery operators have a pressing requirement to improve the efficiency of flow control in their plants and they want to know from the Distributed Control System (DCS) if valves are open or closed. To meet this challenge, Rotork Gears has recently introduced the SPI Smart Position Indicator, designed to provide a vastly improved, more robust, reliable and accurate solution compared with previously available equipment. This innovative solution has led a Spanish end user to place an order for approximately 900 units. With an SPI installed, the control centre is able to monitor any of the valves in the refinery, so operational control is more accurate.
