Embodiment Construction
[0028] Embodiments of the present invention will be described in detail below in conjunction with the drawings.
[0029] figure 1 It is a structural schematic diagram of the ultrasonic and electrical dual-mode measurement system in the measurement method of the present invention. The electrical sensor is described by taking a conductance ring sensor as an example. The measurement system consists of a group of electrical sensor arrays 2 installed on the experimental pipe section 1 and an electrical signal generation and acquisition unit 4 connected thereto, a group of ultrasonic sensor arrays 3 and an ultrasonic signal generation and acquisition unit 6 connected thereto. The electrical sensor array 2 is composed of four ring-shaped metal electrodes embedded in the inner wall of the pipeline at certain intervals; the ultrasonic sensor array 3 is composed of a group of dual-crystal ultrasonic transducers with integrated transceiver installed on the same side of the pipeline.
