Flow Measurements for Future Environment and Energy Technology
Masaki Takamoto
Abstract:
The role of flow measurement is already very important for trading of high pressure natural gas and liquid hydrocarbon. Various new technologies are developed for these flow measurements, such as accurate and reliable ultrasonic flowmeter and Coriolis flowmeter using sophisticated computer software. However, present research and development for environment and energy technology requires flow measurement in very different conditions and it is becoming more difficult and important to meet these requirements. In this presentation, development of flow measurements for exhaust gas from vehicles and standard gas production for environment chemical analysis are introduced. New flow standard of pulsating flow and very small gas flow are developed for these purposes. Hydrogen is considered as the clean next generation energy and many technologies are being developed such as fuel battery. A new flowmeter for hydrogen is required to evaluate fuel battery performance. An ultrasonic flowmeter is developed for hydrogen. Also, up rating of existing nuclear power plants is considered as the useful method to reduce exhausting CO2 from power station. Calibration method of large ultrasonic flowmeter used for the up rating is discussed.
