Cygnus: ROV Mountable Ultrasonic Thickness Gauge

Availability: Rental, Sale

Cygnus offer two dedicated ROV mountable thickness gauges, the M5-ROV-2K up to 2000m depth rated, and the M5-ROV-4K up to 4000m depth rated. This gauge is versatile and designed to measure metal thickness in the harshest subsea operating conditions – without the need to remove coatings.

Features

Selectable Deep Coat mode for measuring through coatings up to 20mm thick.

Supplied with CygLink software to display and log thickness measurements from the ROV on a computer at the surface which can be saved to a file and printed out.

CygLink has two data logging facilities: Quick Log for simple recording of thickness measurements and structured mode with four templates available. Single Point, Multi Point, Grid Point and Key Point.

The ROV Gauge sends thickness measurement data to the surface via an RS-422 serial link, Cygnus can supply the RS-422 umbilical cable up to 1,200m in length.

For longer distances the ROV Gauge can output data in RS-232 mode.
