Steel pipelines are protected against corrosion through cathodic protection. For optimal protection, cathodic protection needs to be maintained. This means that the voltage and current need to be within the defined boundary. With this remote monitoring device, the voltage and current can be measured on a continuous basis. As a result, damage and degradation are detected earlier, operational costs are reduced, and the asset lifetime is increased.
The online Withthegrid application is designed to give the user a complete overview of asset performance. For example, you can view historic performance, set thresholds and alarms, and enrich the overview with manual measurements from the field.
Deep integration with leak detection devices allows for:
- Adjusting measurement frequency
- Measure the open circuit potential or off-potential
- Turning off cathodic protection (e.g. for works)
- Switch the rectifier (e.g. for DCVG inspection)
- Configure the rectifier (works with Amstel rectifiers)
- Measure once every second for 5 minutes up to 24 hours
- Easy installation by smartphone or tablet with direct connectivity to device
-Modern LTE-M mobile communication allows for communication with device even during setup.
- 8 channel measurement
-3 channel AC+DC and additional current AC+DC measurement for a coupon
- On/off measurements and data logging combined
-Define your own desired measurement frequency (1X/5 minutes to 1X/week) and carry out more frequent samplings for stray current measurements (every second for 5minutes or every second for 24 hours). Automatic calculation of min, max and standard deviation for rectifier connected devices.
- Coupon measurement with relay
-Carry out coupon measurements including AC+DC current measurement
- Time synchronisation and coordinates
-Electronic time synchronisation allows for synchronized switching of rectifiers and test points and measurements.
- Rectifier switching and control
-The device can also switch rectifiers with an external relay. In addition with a 0-10V/4-20mA output signal it can also control any rectifier.
- Cloud based advanced monitoring software
-Create alerts, monitor thresholds, assign actions for your CP personnel all from one always accessible dashboard
-Insert manual measurements including standard routes
