Lih, Shyh-Shiuh; Lee, Hyeong Jae; Bar-Cohen, Yoseph; Badescu, Mircea; Cervantes, William; Simonini, Alan, 2017, "Development and Testing of a Multi-Transducer System for Measuring Height of Condensed Water in Steam Pipes with Steady-State and Turbulent Flow Conditions", https://hdl.handle.net/2014/46254, 2017 SPIE Smart Structures and Materials/NDE Symposium, Portland, Oregon, March 25-29, 2017, JPL Open Repository
One of the critical requirements for ensuring the safety of a steam pipe is to monitor the condensed water level under operation. For this objective, the authors initially developed methods and obtained preliminary test results based on the use of ultrasonic pulse-echo transducer... |
