Emerson Process Management’s Rosemount Analytical GDU-Incus ultrasonic leak detector received the Det Norske Veritas (DNV) type approval. The device is suitable for use on board marine vessels, including liquefied natural gas and liquefied propane gas carriers, crude oil tankers, and FPSO units. Because the detector responds to the ultrasound produced by the leak, extreme weather and wind on vessels and platforms do not affect its performance. Using four acoustic sensors that constantly monitor wide areas for ultrasound generated from the release of pressurized gas, the device is suited for monitoring ventilated outdoor applications and responds instantly to methane, hydrogen, and other low-molecular-weight gases. The company said it does not require calibration or replacement for the life of the instrument, and an integrated self-test ensures fail-safe operation.
