MOBILTEX CorTalk RMU3 Remote Monitoring and GPS Interruption for Rectifiers

- Quickly and Affordably Add Two-way Communication for Accurate, Remotely Controlled Configuration and GPS-Synchronized Interruption of Rectifiers
-
Description
Gain deep insight into the performance of your CP system with continuous remote monitoring capabilities. The RMU3 is a small, two-piece device that can be easily installed into a rectifier cabinet and features a full range of configurable functions to collect critical measurement data.
Two-way information can be transmitted via satellite or cellular network as frequently as every few hours to provide a highly detailed view of the CP system and identify short-lived events that may impact CP performance.
When combined with CorView web analytics platform, pipeline operators can use a network of RMU3 devices to instantly evaluate overall CP performance, identify areas of concern and remotely manage interruption activities.
