|Improved Stability and Repeatability at Normal and Elevated Temperatures|
Billerica, MA, USA June 15, 2009 The DM5E family is the latest generation of portable, ultrasonic, corrosion monitoring thickness gauges from GE Sensing & Inspection Technologies. The DM5E series offers significant improvement in performance over previous corrosion thickness gauges in terms of thickness measurement and stability and repeatability at normal and elevated temperatures. Its designed for operation in the harshest working environments, performing wall thickness measurements on pipelines, pressure vessels and storage tanks in the oil and gas industry, as well as the petrochemical and power generation sectors.
Our new DM5E family allows operators to choose the level of thickness measuring functionality to suit them, while its flexibility allows them to upgrade their instruments whenever they wish, says Stefan Frank, product manager at GE Sensing & Inspection Technologies. The instruments come with a new range of ultrasonic probes to ensure optimized performance even at high temperatures.
The new corrosion measurement solution is available in three versions; the DM5E Basic; the DM5E; and the DM5E DL. All versions weigh just 223g, including their AA batteries, which allow up to 60 hours operation. They feature an LCD data display, which is backlit to be visible in all lighting conditions, and operation is carried out with one hand using a user-friendly operator interface.
The DM5E instrument additionally offers the DUAL MULTI operating mode, which allows metal thickness to be measured through coatings. Protective coatings, including paint, contribute significant error to thickness measurements of underlying metal walls when using conventional methods. In addition, the removal of coatings, and their subsequent reapplication, involves considerable cost and time.
The DM5E DL version has a built-in datalogger, with a capacity to store up a massive 50,000 reading in grid and linear files. This makes the measurement data available for further processing. Using GEs UltraMATE software, measurement data files can be transferred from the instrument to a PC, where they can be analyzed and stored. The Basic version can be simply up-graded into a DM5E instrument and both DM5E Basic and DM5E can be field-upgraded to become DL versions.
