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