Abstract:

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 lbhr. It was operated during and recalibrated after 104 hours exposure to a contaminated fluid flowing at approx. 1900 lbhr. Response time was determined. The flowmeter can operate in laminar, transitional, and turbulent flow, using a special method of weighting the profile.
