Cygnus ROV mountable
Multiple Echo Ultrasonic Thickness Gauge
Cygnus Instruments offers three versions of the ROV Mountable using our Multiple-Echo technology, designed for undertaking subsea surveys. The Deepwater is rated to 10,000 ft (3,000 m); the Shallow water is rated to 3,000 ft (1,000 m) and the Mini is rated to 1,500 ft (500 m). These units have been designed to be mounted on most types of Work Class ROV’s using a manipulator facility or mounted on small inspection ROV’s with or without a manipulator facility.

Three models available:
- Deepwater pressure tested to 10,000’ (3,000 m)
- Shallow Water pressure tested to 3,000’ (1,000 m)
- Mini pressure tested to 1,500’ (500 m)
- 16' (5 m) of probe cable for routing around most Work Class
ROV's with the Deepwater and Shallow water units
- 1' (.03 m) of probe cable for the Mini
- Power supply normally taken from the ROV or one twisted pair
- Only one twisted pair is required to transfer the data to the surface
- The probe does not need to touch the surface under test, as measurements can be taken through 3/16" (5 mm) of water
- Stable calibration – linear accuracy – no zero adjustments
- Dedicated software for displaying the measured results, storing
the measurements, printing 8 ½" X 11" meaningful reports and
setting the calibration of the gauge.
- Self verification of the measurements to ensure accuracy
- Echo strength indicator to aid measuring
- Inch/Metric switchable
| OPTIONAL PROBE HOLDER |
| Cygnus Instruments offer a dedicated probe holder to be held by a manipulator arm or to be mounted aboard the ROV. The holder is spring loaded to help in aligning the probe and protecting the probe from excessive force exerted by a manipulator arm. |
