| Abstract: | To meet the requirements of large air flow test for a LOX/LH2 rocket engine, Annubar mass flowmeter is adopted to measure the air flow on the basis of comprehensive analysis and re-search. The structure and working principle of the Annubar flowmeter are introduced. The flowmeter installation on pipeline and its flow data calculation are described in detail. The test data of Annubar flowmeter and Corioris mass flowmeter is compared, and also the application effect of Annubar flowmeter in the air flow test is illustrated in this paper. The performance characteristics and applica- tion prospect ofAnnubar flowmeter are discussed. |
