MA-1™
Monitored Sacrificial Anode
The cathodic protection "fuel gauge." Monitored anode performance allows operators to predict CP system life.
The Polatrak MA-1 provides a reliable, accurate method for monitoring anode performance and consumption. It can be hardwired to the surface, or connected to a SunStation subsea readout, making it suitable for any depth.
The MA-1 allows accurate logging of the total number of Ampere-hours delivered by the anode. The time-consuming acts of cleaning an anode and then visually estimating consumption (an inherently unreliable exercise) are no longer required. The unique design of the monolithic isolators used in the system provides 100% life cycle reliability; there are no insulated flange joints or other unreliable components. The double armored wires used on all Polatrak instruments ensure full life cycle performance.
Polatrak monitors have an excellent track record of success and are installed on more offshore structures worldwide than any other fixed monitoring system. The system has been applied to all galvanic anode types, platform anodes, flush mount anodes as well as onshore and offshore pipeline bracelets.

Key design points
1. The cathodic protection "fuel gauge"
The MA-1 allows an operator to accurately measure anode consumption, and therefore the remaining life of the anode without interference. This data for a handful of anodes will give general trends for the entire cathodic protection system.
2. Gives direct verification of CP design criteria
Verification of certain anode performance allows corrosion engineers to evaluate not only the design of a particular system, but of design methodology in general.
3. Designed for any type of anode
The MA-1 system is available for all types of major sacrificial anode (platform anodes, pipeline bracelets, etc.), and can be used offshore or onshore on buried pipelines. The systems is also available sans anode, allowing it to be attached to any required anode in the fab yard.
