Multigauge 4000 ROV Metal Thickness Gauge
Tritex NDT, UK, has upgraded its Multigauge 4000 Series ROV thickness gauges for mounting onto most work-class ROVs. The range includes the Multigauge 4100 and Multigauge 4400 which are for use in depths of 1,000m and 4,000m respectively. The Multigauge 4100 is now made from acetal and the Multigauge 4400 from titanium for extra durability.
The gauges are used for inspecting metal thickness to check for corrosion in pipelines, pilings, ship's hulls and subsea structures without the need for using divers. They use multiple echo to ensure coatings do not have to be removed, since only the metal substrate is measured. Additionally, they have Intelligent Probe Recognition (IPR) and Automatic Measurement Verification System (AMVS).
Another upgrade includes a selectable RS422 or RS232 output by means of a simple switch on the gauge. To accompany the Multigauge 4000 series, Tritex have developed Communicator Software, for use on a PC or laptop, to display and record the measurements and associated data such as the time and a descriptive label if required. Templates can be set up to store measurements in a grid, string or combination of both.
