“The gauge worked well and we got readings off the hull, I have to admit to being surprised given the corroded state of the hull ” Ministry of Defence DESS Salvage and Marine Operations (SANMO), United Kingdom The Multigauge ROV 4100 and 4400 Underwater Gauges are simple, robust ultrasonic thickness gauges designed to be mounted onto all types of work class ROV's. There are two models in the range, the Multigauge ROV 4100 which has a depth rating of 1000m and the Multigauge ROV 4400 which has a depth rating of 4000m. Both gauges have been designed and built to survive extremely harsh conditions...

Features • Ignores coatings up to 6mm thick using multiple echo. Coating Plus+ ignores coatings up to 20mm • Easy to use datalogging software • Various output types, including ASCII to overlay measurements onto video • Compatible with most ROV's • Optional probe holder for correct presentation of the probe • Intelligent Probe Recognition (IPR) • Automatic Measurement Verification (AMVS) • Free calibration for the life of the gauge "The gauge gives quick and accurate readings, requires far less surface preparation than other makes we have used and locks on much fasten it can speed up the survey...

Probe Holder The Multigauge ROV Probe Holder has been designed to accurately present the ROV probe onto the surface being measured, whether it is curved or flat. The ingenious design means there are no moving parts to get clogged with silt and seaweed and yet there is a 75° freedom of movement in all directions - there are no axial restrictions. It is made from titanium for strength and lightness. The probe can be mounted slightly recessed into the holder to prevent damage to the probe if a collision with the surface occurred. Measurements are unaffected by the small water gap due to the Multiple...

Communicator Software Tritex Communicator software displays live measurement results from the Multigauge 4000 onto either a laptop or PC. Templates can be preset based on a grid or string of measurements. This gives maximum versatility for a wide range of applications including measurements on pipelines, pilings or ship hulls. As well as storing measurement data, Communicator software also has the option to store the time, date and an identifying label for each measurement. In addition, various settings within the gauge can be changed from the software to optimise performance. The stored data...
