Abstract
An integrated circuit includes one or more central processing unit (CPU) cores configured to cause a first ultrasonic transducer to generate ultrasonic signals into a fluid moving in a pipe and the first or a second ultrasonic transducer to receive the ultrasonic signals from the fluid. The CPU core(s) also compute a first value indicative of at least one of a standard deviation and a time correlation based on the received ultrasonic signals. The CPU core(s) further determine a second value indicative of a volume of gas bubbles in the fluid using the computed first value indicative of the at least one of the standard deviation and time correlation.
