April 4, 2014 - Flowserve announced the Limitorque Master Station III, a digital network solution that provides complete control, monitoring and diagnostics for up to 250 Flowserve Limitorque valve actuators.
The Master Station III’s modular, hot-swappable, redundant design reduces commissioning and configuration time. If the active module fails, the advanced design of the Master Station III initiates the standby module to immediately take over the network for seamless control. When a module needs to be replaced or repaired, it can be removed and a new module can be installed without taking the device offline, reducing costly downtime. Another capability of the Master Station III is the slave register polling schedule that can be configured in order to optimize overall network communication performance and enable end users to download status and diagnostic information of critical valve actuators more frequently.
A built-in network time protocol (NTP) provides time synchronization with the host controller, resulting in harmonized date and time stamped diagnostic logging. When an alarm is triggered, an e-mail notification is automatically sent to facility operators. The Master Station III can serve as an interface device between the host and the valve actuator network, or it can stand on its own. It features a simple touch-panel Human Machine Interface (HMI) supporting five languages: English, Spanish, German, French and Italian; and an external monitor and mouse can be connected through VGA and USB ports. The new digital network controller is compatible with Flowserve Limitorque MX, QX, and L120 field units and can be used for power, petrochemical, oil and gas, water and wastewater applications.
