Summary:An apparatus for detecting and measuring gas voids in a pipe with a fluid includes a first ultrasonic transducer externally disposed on the pipe. The apparatus includes a second ultrasonic transducer externally disposed on the pipe. The apparatus includes a multiplexer, transmitter, receiver, controller and processor in communication with the first transducer and the second transducer which in combination identify a void in the pipe from ultrasonic measurements of properties of the fluid in the pipe. A method for detecting and measuring gas voids in a pipe with a fluid includes the steps of measuring properties of the fluid internal to the pipe with transmissions of ultrasonic energy from transducers externally disposed on the pipe. There is the step of identifying a void in the pipe from the properties of the fluid internal to the pipe using signals processed by processor.
