• Optional dedicated probe holder to allow measurements on curved or flat surfaces.
• Small, lightweight and easy to install.
• Single twisted pair to transfer data to urface.
• Power supply taken locally from ROV.
• Probe does not need to touch surface under test.
• Measurements can be taken through 5 mm of water.
• Readings not influenced by the probe orientation.

Typical Applications:
Shipping industry, deepwater pipeline inspection, offshore industry, pier & piling inspection.

The Cygnus ROV Range comprises of three Multiple Echo ROV Mountable thickness gauges rated at different depths:
- Cygnus MINI ROV - Rated to a depth of 500 m
- Cygnus ROV 1000 - Rated to a depth of 1000 m
- Cygnus ROV 3000 - Rated to a depth of 3000 m
Each ROV is designed to be mounted onto a Work Class ROV. Thethickness measurement data is transmitted topside via a single twisted-pair RS422 link. Dedicated Windows software then displays thickness readings, which can be stored or data-logged as required.

• Pressure rated to depth of 1000 m or 3000 m.
• 15 ft (5 m) of probe cable for routing around most ROVs.
• Power taken from ROV.
• Only one twisted pair is required to transfer data to surface.
• Probe does not need to touch surface under test, measurements can be taken through 5 mm of water.
• Readings not influenced by the probe orientation.
• Dedicated software for topside PC display of measured results, data storage and gauge calibration.

Typical Applications:
Shipping industry, deepwater pipeline inspection, offshore industry, pier & piling inspection.

Cygnus Multiple Echo Technology

With multiple echo technology, readings are taken by measuring the time delay between any three consecutive backwall echoes. The time T1 (for coating thickness) is ignored. The times T2 and T3 are equal to the time that it takes for sound to travel through the metal. Only by looking at three echoes can the measurements be made for the metal thickness, where T2 = T3.
