ABSTRACT:
A plurality of water tanks hold a plurality of ultrasonic transducers, each providing a different angle of incidence for ultrasonic radiation for a tube or pipe passing through the tank. Water of a specific temperature is fed to the particular tank being used and in conjunction with a particularly oriented transducer, a particular test angle of refraction is established. Through a particular range of different transducer orientations in conjunction with a temperature range from about 5.degree. to 40.degree. C., a rather wide range of possible refraction angles can be established.
