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.
Claims19
A method, comprising:
- receiving a first ultrasonic signal from a reflector, the first ultrasonic signal reflected by the reflector in fluid moving in a pipe;
- determining a first amplitude based on the first ultrasonic signal;
- receiving a second ultrasonic signal from the reflector, the second ultrasonic signal reflected by the reflector in the fluid moving in the pipe;
- determine a second amplitude based on the second ultrasonic signal;
- compute a time correlation of the first amplitude and the second amplitude;
- and
- determine, based on the time correlation, a value indicative of a volume of gas bubbles in the fluid.
A system, comprising:
- a pipe comprising moving fluid;
- a first ultrasonic transducer configured to generate a first ultrasonic signal in the moving fluid and a second ultrasonic signal in the moving fluid, wherein a reflector causes the first or a second ultrasonic transducer to receive the first ultrasonic signal from the moving fluid, wherein the reflector causes the first or second ultrasonic transducer to receive the second ultrasonic signal from the moving fluid;
- and
- a controller configured to:
- determine a first amplitude based on the received first ultrasonic signal;
- determine a second amplitude based on the received second ultrasonic signal;
- compute a time correlation of the first amplitude and the second amplitude;
- and
- determine based on the time correlation a value indicative of a volume of gas bubbles in the moving fluid.
