Ultrasonic Devices Designed for Concentration Measurements in Reservoirs
Ultrasonic spectroscopy is a rapid, on-line, noninvasive measurement technique for suspension characterization of different particle sizes and wide-ranging concentrations. This study presents the design and fabrication of two experimental systems to simultaneously measure the sediment concentration of ultrasound wave propagation in liquid. Each monitoring system includes design and manufacture for an ultrasonic transducer, an electric transmitting and receiving circuit, and data log. This work also integrates these components into a portable type system operating underwater at 100 meters depth, and a fixed chamber type able to draw water from various depths. Measurement results show that ultrasonic attenuation variations are driven by concentration. The chamber type and portable type ultrasonic measurement system took successful measurements in the Shihmen and Tsengwen reservoirs during several typhoons.
