Mobiltex CorTalk - Model RMU1-ER -Electrical Resistance (ER) Corrosion Probes
The CorTalk RMU1-ER collects and transmits a measurement of the corrosion rate near the pipe surface through the use of sacrificial electrical resistance (ER) probes as frequently as every few hours via satellite or cellular network. This provides technicians with highly detailed, near real-time measurement data that is useful in determining the underlying cause of corrosion and the ability to measure changes in corrosion conditions including the effectiveness of repairs, temperature cycles or sudden environmental changes.
Test Station Remote Monitoring of Electrical Resistance (ER) Corrosion Probes
The RMU1-ER is designed to be compatible with a wide range of ER probes. The RMU1-ER has the capability to measure ER probes constructed with tubular, wire, cylindrical, flush, spiral and strip geometries.
In addition to metal loss, the RMU1-ER can also measure the ER probe potential when a reference cell is connected. As the ER probe is typically electrically connected to the protected structure, the structure potential can be measured.
Combined with the CorView Cloud Platform, pipeline operators can implement and control a network of RMU1-ER devices to gain deep insight into the performance of the CP system, generate reports and instantly identify areas of concern.
