The Deep C Meter™ is the premier ROV cathodic-protection survey system for use in deep water.

The Polatrak® Deep C Meter™ is designed for rugged service on a work-class ROV. Each unit is built and tested in Deepwater's Houston manufacturing facility.

The Deep C Meter 3000 AD™ is the premier ROV cathodic‐protection survey system for use in deep water. The unit can integrate fully with ROV systems for power and data transfer, or it can operate as a visual inspection unit with no interface with the ROV umbilical. It's designed for rugged service on a work‐class ROV at water depths up to 3000 meters (10,000 feet). The unit can integrate fully with ROV systems for power and RS‐232 serial data transfer. The ROV‐II™ contact probe (included) is mounted on a convenient, shock‐absorbing T-handle. In addition to the digital data stream, the always‐on display allows survey teams to operate even when serial communications are not available. The display brightness can be remotely adjusted in real‐time to accommodate a variety of lighting and camera conditions.

The optional electric field gradient (EFG) probe enables any AD series meter to detect electric currents in seawater, allowing touchless measurement of anode activity.

Accurate video and digital output

The Deep C Meter 3000 AD™ provides real‐time data through three LED displays and a continuous RS232 (standard ASCII string) digital feed. The included Survey™ software makes planning, executing and reporting a CP survey much more reliable, convenient and precise than ever before. Having a visual backup of the data provides more confidence during the survey and an easy way to double‐check your results when you return to shore.

Works with ROV power

The Deep C Meter 3000 AD™ is 24V DC ROV powered, which eliminates the need to open the pressure housing to change batteries and replace O‐rings. Cabling can be interfaced with the ROV either through a splice or oil‐filled cables.

Stand-alone version available

We also offer the Deep‐C‐Meter 3000™ unit, which is a battery powered version that does not interface at all with ROV systems. All readings are taken from the subsea readout via the ROV camera. Upgrade kits for these non‐AD units are also available.

Survey is designed to make cathodic protection surveys quick and easy and is included free with every Deep C Meter™ 3000 AD purchased. The software can work in multiple modes to support any survey requirements:

Traditional stab + EFG – The ROV take stabs and EFG readings, but no remote electrode readings.

Remote electrode – > Remote electrode ‐ The ROV takes stabs and EFG readings. In between stabs the ROV also takes remote variance measurements with a remote electrode deployed over the side of the vessel or attached to the ROV’s TMS.
