Ultrasonic-based gas flowmeter for harsh environmental conditions
e & i Elektrotechnik und Informationstechnik, 2009 The applicability of an ultrasonic transit-time gas flowmeter can be extended regarding its gas temperature range (up to 450°C). We used computational fluid dynamics and ray-tracing techniques to investigate thermally-related effects that influence the sound propagation inside the flowmeter.
