Detailed description of the invention
With specific embodiment, the utility model is described in detail below in conjunction with the accompanying drawings.The present embodiment is new with this practicality
Implement premised on type technical scheme, give detailed embodiment and concrete operating process, but this practicality
Novel protection domain is not limited to following embodiment.
Embodiment 1
A kind of ultrasonic calorimeter pipeline as shown in Figure 1, including the water inlet segment 1 being sequentially connected with, measures pipeline section
3 and water outlet pipeline section 2, described measurement pipeline section 3 is used for installing upstream transducer 4 and downstream transducer 9.Described
Measure pipeline section 3 inwall be fixed with the reflecting surface for reflectance ultrasound ripple signal, including for reflecting upstream transducer
