CP Remote Monitoring is a technology that allows users to collect information about the environment surrounding the anode and cathode, without having to touch them. This data is collected through the difference in voltage between the anode and cathode. This can be used to monitor the effectiveness of the CP system. It can also be a great way to help detect corrosion coupons. source: https://www.rmftek.com/cathodic-protection-remote-monitoring-products/

Coupon can be used to monitor the effectiveness of the CP system

Using corrosion coupons is a convenient and relatively inexpensive way to monitor the cathodic protection system’s effectiveness. It can be used to evaluate the level of cathodic protection at a given location, assess the suitability of specific materials, and monitor a chemical treatment program.

To manage the coupons correctly, the remote monitoring devices need to be equipped with an integrated interrupter, to control the connection between coupon and pipe. The best choice is a solid state interrupter which allows fast operational timings and avoid any bouncing that could affect the measurements, as well as the flowing of the polarization current without introducing any further resistance than the shunt one, used to perform its measurement.

The most common method is the instant disconnect structure-to-electrolyte potential measurement. This involves momentarily disconnecting the coupon from the pipeline while measuring the current. The resulting voltage drop is proportional to the magnitude of the current flowing through the electrolyte. The difference between the “on” and “off” mV drops can then be used to calculate the net current.

Flexible Data Acquisition and Logging

PWATCH-2 incorporates total eight channels each of which may be sampled at user-configured intervals and logged. Each channel incorporates separate alarm limits and alarm counts filter.

The most impressive part of this system is its ability to measure multiple parameters in order to provide real-time data on the condition of the protected object. As such, the PWATCH-2 system can be deployed to support a variety of applications. Combined with its other features, the PWATCH-2 system provides a robust cathodic protection monitoring solution that fits right in with the rest of the equipment.

Cathodic Protection Remote Monitoring Solution

Use of remote monitoring of cathodic protection systems has become a critical component for pipeline operators. The PWATCH cathodic protection remote monitoring solution detects potential corrosion problems and immediately alerts the operator.

With the support of WEB-based architecture, cathodic protection operators can access real-time data at any time. PWATCH is an easy-to-use and fast solution supporting an effective reporting plug-in as well as graphical and digital data display.

The interactive mapping service was specifically designed for administrators and cathodic protection operators. It provides with all the important information of cathodic measurement points on a map together with the tools required for remote configurations.
