The Cygnus Mini ROV Mountable thickness gage has been specially designed to be mounted onto small observation ROVs with or without a manipulator facility. Built in conjunction with VideoRay, this mountable subsea thickness gage will allow the operator to carry out an ultrasonic thickness measurement in areas that have previously been unfeasible using larger ROVs or divers. The multiple echo thickness gage measures metal thickness and corrosion without removing protective coatings.
Dedicated software displays the time, date and thickness readings on the surface which can all be stored or logged. Alternatively, an optional Topside Repeater (TSR) is available which has the facility to display the thickness measurements remotely and overlay them on to a video signal. This allows the measurements to be superimposed on the ROV camera’s monitor screen.
The unit is pressure tested to 1,500 ft (500 m).

CygLink is a Windows® application for PCs that allows remote viewing, control and data logging for the Cygnus Mini ROV gauge. CygLink displays the
thickness measurements in real-time and these can then be logged.
Settings within the gauge can be controlled remotely through CygLink, including calibrating the gauge to a known thickness and inputting a velocity of sound for the material being tested. There is also the option to choose the velocity from a list of common materials.
Each recorded measurement can have pre-set comments and/or a manually typed note added.
The data logged measurements can be recorded in a Linear List or a TwoDimensional Grid. Each survey can have separate groups of measurements within it and a “Reference” and “Minimum” thickness set.
Reports can be created either as a .pdf or the data exported to a .csv file. The measurements can also be represented graphically.
Top Side Repeater (TSR) - Optional
|The Top Side Repeater is a small display unit that can be used to display the thickness measurements sent from the Cygnus Mini ROV gauge to the surface.
Kit includes data and video cables.
TSR Video Overlay Facility
|The Top Side Repeater can also superimpose the thickness measurements on to a composite PAL or NTSC video signal to display it on a monitor screen and/or the video recording of the survey. This provides a thickness measurement that can be linked to a position or place in the video recording.|
