摘要： PROBLEM TO BE SOLVED: To enhance the accuracy (resolution) of a level measurement. SOLUTION: Two probes 5, 6 are attached to the outer wall surface of a liquid tank 1. Ultrasonic pulses which are transmitted toward the inside of the liquid tank 1 from the upper probe 5 are received by the lower probe 6 as echo pulses having a delay time after they are multiple-reflected by the inside wall of the liquid tank 1. A signal detection means 9 by which the signal intensity of the received echo pulses is detected so as to be separated in every delay time is installed. A level conversion means 10 by which the level at the inside of the liquid tank 1 with reference to the mounting position of both probes 5, 6 is converted on the basis of the signal intensity and the delay time which are detected by the signal detection means 9 is installed. The level conversion means 10 is constituted in such a way that the level is converted by taking into consideration a case in which longitudinal waves and transverse waves are mode-converted when the ultrasonic pulses are multiple-reflected by the inside wall of the liquid tank 1.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic stress measuring apparatus and an ultrasonic stress measuring method which prevent the upsizing of an apparatus and improve working efficiency.
SOLUTION: By first and second horizontal transverse wave probes P1, P2, two pieces of ultrasonic sonic velocity data the vibration direction of which is horizontal are obtained. By determining the average value of the two pieces of sonic velocity data, the average sonic velocity data are regarded as data obtained by transmitting/receiving a horizontal transverse ultrasonic wave at the intermediate position between the two transverse wave probes P1, P2, that is, at the position of a longitudinal wave probe P0. A similar thought holds for first and second vertical transverse wave probes P3, P4. By arranging the probes as shown in Fig.1(b), therefore, the similar effect as a case in which the probes are exchanged is obtained without relying on a drive mechanism.
