Development, Evaluation, and Testing of an Active Ultrasonic Cross-Correlation Coal-Slurry Flowmeter

摘要

This paper describes the development of an active ultrasonic cross-correlation flowmeter at Argonne National Laboratory (ANL). The flowmeter includes transducer standoffs for high-temperature application, an integrated electronic package for signal generation and conditioning, and data processing software operating on an IBM-AT computer. The flowmeter has been tested for coal/water and coal/oil slurries over a wide range of concentration at the ANL Solid/Liquid Flow Test Facility (SLFTF) and at the SRC-1 coal-slurry feedline. Test results leading to the selection of standoff design, operating frequency, signal filtering, and transducer spacing are discussed. Flowmeter performance is evaluated in terms of accuracy, response time, and consistency. 6 refs., 11 figs. (ERA citation 12:019957)
