Remote Test Station Monitoring of Pipe-to-Soil Potential Engineered for Large-Scale Deployments
MOBILTEX introduces the CorTalk RMU1-LITE — a robust and purposefully-engineered device that enables pipeline operators to effectively automate the collection pipe-to-soil potential measurement data from Cathodic Protection (CP) test stations in extreme or difficult-to-access locations. It’s now possible to realize the operational, functional, and safety benefits of large-deployment remote CP data collection.
High volume deployments within operational budgets are now possible
The CorTalk RMU1-LITE offers user-selectable intervals, greatly enhancing the amount of pipe-to-soil data that is automatically collected as compared to manually obtained annual pipe-to-soil potential readings. Pipeline operators can take advantage of this capability to collect multiple measurements throughout the year, providing a richer data set to understand seasonal variations or short-term operating irregularities that can negatively impact CP system performance. This flexibility also provides a measure of future-proofing since the RMU1-LITE will be able to meet regulatory requirements for more frequent data collection that may come into force.
The RMU1-LITE also has a unique feature that adds to it’s autonomy and reliability, it can collect separate pipe-to-soil potential measurements from two connected reference cells. This allows technicians to use our CorView Cloud Platform to remotely compare the results and validate whether the reference cells are functioning properly. During an interruption event, the device can also capture an instant-off potential measurement, meeting the data requirements for annual level of protection surveys and further reinforcing the operational insights provided by more granular measurements.
| Features | Benefits |

Frequently asked questions
What is the difference between an RMU1-I, RMU1-S and RMU1-G antenna?
The RMU1-I uses Iridium satellite for connectivity. The RMU1-S is the Globalstar satellite communications variant of the RMU1. The RMU1-G is the cellular version.
Which cellular network does the RMU1-G antenna utilize?
AT&T in the USA, Rogers in Canada. Cellular provider coverage maps can be used to ascertain if your sites have cellular coverage.
The RSSI (Receive Signal Strength Indicator) is different each time my RMU1-I reports in. Is this normal?
Yes, this is normal. The Iridium satellites the RMU1-I utilizes are in-motion orbiting around the earth. When the satellite is directly above the antenna, it will report a strong RSSI. If the satellite is low on the horizon when the RMU1 transmits, a lower RSSI is possible. The RSSI will change throughout the day as the satellite constellation moves through its orbit.
How can I tell if my RMU1 is transmitting a message to CorView?
Look for “Tx” and an antenna icon near the bottom left corner of the RMU1’s display. This indicates that the communications antenna is transmitting a message to CorView. There could be minor delays depending on network traffic and site coverage.
