<P>PROBLEM TO BE SOLVED: To provide a reliable ultrasonic measuring device, with a simplified process for attaching a ultrasonic transducer to a flow channel to be measured, which reduces chances of errors at site. <P>SOLUTION: An attachment structure comprises an ultrasonic transducer 14 having a bottomed cylindrical case 1, acoustic matching layer 5, and a piezoelectric body 6, an insulator 15 made of electrical insulating material, an airtight seal material 18, and a to-be-attached part 16. The ultrasonic transducer 14 is attached to the to-be-attached part 16 through the insulator 15. The seal material 18 is inserted between the ultrasonic transducer 14 and the insulator 15, and between the insulator 15 and the to-be-attached part 16, so that vibration propagation between the ultrasonic transducer and a flow channel to be measured is reduced with secured insulation and sealability. In a process for attaching the ultrasonic transducer to the flow channel to be measured, the ultrasonic transducer is easily attached by mounting the insulator and the seal material on the flow channel to be measured in advance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
