Cygnus Instruments offers two dedicated ROV mountable thickness gauges in this design. Available in 2000 m and 4000 m depth rated, these multiple echo ultrasonic thickness gauges are truly versatile and designed to measure metal thickness through coatings in the harshest operating conditions. Dedicated software displays the time, date and thickness readings on the surface which can all can 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.
