MOBILTEX CorTalk RMU1 Remote Monitoring for Test Stations with Coupons and Bonds

Designed To Fit Entirely Inside a Standard CP Test Station, The RMU1 is a Small, Powerful Tool for Remote Monitoring of CP Single or Double Coupons and Structure Bond Applications.


The RMU1 collects and transmits CP performance data and GPS location as frequently as every few hours via satellite or cellular network. This provides technicians with a highly detailed, near-real-time view of the CP system and helps identify short-lived events that may impact CP performance.

When combined with the Mobiltex CorView web analytics platform, pipeline operators can implement a network of RMU1 devices to gain deep insight into the performance of the CP system, generate reports and instantly identify areas of concern.

RMU1 Generation 4 is also capable of two-way communication and can provide remote, GPS-synchronized interruption with the addition of MOBILTEX INT1, a compact accessory module.
