Description
The RM4014 and RM4015 are satellite-based, reliable, two-way, wireless remote monitoring units (RMUs) for cathodic protection applications, and they’re Built Bullhorn Tough. The only difference between these units is that the RM4014 is mounted externally, while the RM4015 is small enough to fit inside most rectifier cabinets. Otherwise, both units have the same functionality.
These units monitor pipelines, well casings, tanks and other assets by reading rectifier AC and DC volts and amps, pipe-to-soil potential, shunts, and more. Additionally, they can survive the harshest of conditions, with built in surge protection and an optional high-energy surge arrester.
The RM4014 and RM4015 remotely collect cathodic protection (CP) measurements used to demonstrate corrosion mitigation effectiveness. They monitor pipelines, well casings, tanks and other assets by reading rectifier AC and DC volts and amps, pipe-to-soil potential, shunts, and more. GPS synchronized interruption is available at time of purchase or as a field upgrade. The Orbcomm IsatData Pro satellite network is used for global, low-latency, two-way communications. Measurements are automatically uploaded to Bullhorn Web, a web-based asset manager that works with PCS™ to form a full end-to-end regulatory compliance solution from field measurement to reporting. The RM4014 is mounted externally, while the RM4015 is small enough to fit inside most rectifiers.
Feature | Benefit |
