A compact and powerful tool for remote monitoring of CP single or double coupons and structure bond applications

The CorTalk 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.

Combined with the CorView Cloud Platform, pipeline operators can implement and control 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 CorTalk INT1, a compact accessory module.

FeaturesBenefits
Fast, simple installationThe compact, weather-proof RMU1 is designed to fit entirely inside a standard CP test station and can be installed in about 20 minutes
Engineered for expandable functionalityRMU1 Generation 4 hardware platform allows connection of additional external accessory modules like the INT1 for GPS synchronized interruption, the TS1 temperature sensor, and a 4-20mA Mode
Multiple pre-defined configurationsThe RMU1 can be wired for single coupon, dual coupon, separate AC and DC coupons, and bond monitoring applications
Intuitive controls and configurationsThe RMU1 can be easily programmed with our standard Programming Interface and a PC and can also be completed with a compatible iOS or Android-based mobile device and our available Bluetooth Interface
Global communication capabilitiesAvailable with cellular or satellite communication capability, the RMU1 can transmit data from virtually any location. This helps improve the quality and frequency of data collection, while reducing the need for workers to undertake long, potentially dangerous trips, to remote sites
Built to withstand the toughest conditionsLightning, surge and overvoltage protection and broad operating temperature range (-40° to +60°C [-40° to +140°F])
Long-life batteryUser-replaceable standard AA battery provides up to 10 years of monitoring and data transmission and maximizes lightning isolation

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.
