Ultrasonic mass flowmeter for army aircraft engine diagnostics
Lynnworth L.C.
Fort Belvoir (USA): Defense Technical Information Center, 1973. - 116 p.Summary: Development is reported on a new type of ultrasonic mass flowmeter for fuel flow in gas turbine engines, consisting of a flow velocimeter, a densitometer, a time intervalometer, and a metering section containing nonintrusive transducers. The complete system was tested on various liquids at rates up to 5000 lb/hr. It was operated during and recalibrated after 104 hours exposure to a contaminated fluid flowing at approx. 1900 lb/hr. Response time was determined. The flowmeter can operate in laminar, transitional, and turbulent flow, using a special method of weighting the profile.
