  • Patent number: 9476858
    Abstract: Disclosed is a clamp-on-type ultrasonic concentration metering system and method. The clamp-on-type ultrasonic concentration metering system includes an ultrasonic sensor portion and a concentration meter. The ultrasonic sensor portion is attached to an outer wall of a pipe through which a fluid to be measured flows and that transmits and receives an ultrasonic signal through a wall of the pipe. The concentration meter measures a concentration of a substance according an intensity of the ultrasonic signal that is received after passing through the wall of the pipe, the fluid to be measured, and the wall of the pipe by means of the ultrasonic sensor portion.

  • Publication number: 20140238116
    Abstract: Disclosed is an ultrasonic system for measuring both a flow rate and a concentration including: a transmission ultrasonic sensor which is attached to an outer wall of a pipe and which transmits an ultrasonic signal, a concentration-metering ultrasonic sensor which is attached to the opposite outer wall of the pipe and receives the ultrasonic signal that has passed through the wall of the pipe, flow-metering sensors which are attached to the opposite wall of the pipe and receive ultrasonic signals transmitted by the transmission ultrasonic sensor at different points in time, and a unified signal processor which measures a concentration and a total amount of suspended solids according to the intensities of the ultrasonic signals received by the sensors, and measures a flow rate of a fluid using a difference in transit time through a medium.
