Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As Figure 2-3, the syndeton of a kind of transducer gauge outfit of the utility model and measuring tube, comprising: a measuring tube 3, and two ends of measuring tube 3 are connected in the pipeline of testing liquid, and testing liquid flows continuously through measuring tube 3.For ease of the installation of gauge outfit 1, measuring tube 3 is generally all arranged on the pipeline of level; Gauge outfit 1 level is arranged on the outer wall at measuring tube 3 top, two ultrasonic transducers 5 are arranged on the side of measuring tube 3 with identical orientation, its installation place is provided with the mounting hole be communicated with the inside of measuring tube 3, packing washer is provided with in mounting hole, prevent testing liquid from leaking, ultrasonic transducer 5 is fixed in mounting hole, and its end face is towards the inside of measuring tube 3; Measuring tube 3 internal fixtion has acoustic reflection device, the sound wave that one of them ultrasonic transducer 5 is launched is reflected, make sound wave pass testing liquid, and reflex on the end face of another ultrasonic transducer 5, realize the sound wave transmission between two ultrasonic transducers 5; Gauge outfit 1 is connected with two ultrasonic transducers 5, for the data that display measurement arrives.
In the outside of two ultrasonic transducers 5, be provided with watchcase 2, watchcase 2 is connected between gauge outfit 1 and measuring tube 3, for the protection of two ultrasonic transducers 5 and relevant measuring sensor.
Be provided with the described ultrasonic transducer 5 in 4, two, measurement zone in described measuring tube 3 to be communicated with measuring tube 3 inside at the two ends of measurement zone 4 respectively, the sound wave after the reflection of acoustic reflection device, by behind measurement zone 4, is received by another ultrasonic transducer 5.The internal diameter of measurement zone 4 is consistent, to obtain the testing liquid of flow speed stability, improves the accuracy of measuring; The internal diameter of measurement zone 4 is less than the internal diameter of the measuring tube 3 at its two ends, and the two ends of measurement zone 4 are provided with taper surface, for realizing the transition between measuring tube 3, reducing caliber as far as possible and changing the impact caused the flow state of liquid, ensureing the accuracy of measurement data.
During measurement, testing liquid continues to flow in measuring tube 3 and measurement zone 4, ultrasound wave launched by one of them ultrasonic transducer 5, and ultrasound wave enters again measurement zone 4 through the reflection of acoustic reflection device, is then received by another ultrasonic transducer 5 after acoustic reflection device again secondary reflection.Because liquid can affect hyperacoustic biography degree of hastening, under having liquid and no liquid two states by contrast, the sound wave that ultrasonic transducer 5 sends and the mistiming of sound wave received, can record the flow velocity of liquid, the parameters such as the flow velocity recorded are presented in gauge outfit 1 in real time.
As can be seen from the above embodiments, ultrasonic transducer 5 is arranged on the mode of measuring tube 3 side by the utility model by adopting, and eliminates the bubble of fluid generation when showing the flowing of body inner fluid to the impact of metric results.Because gas is lighter, even if create bubble in measuring tube 3, due to the effect of gravity, less bubble may be adsorbed on the inwall of measuring tube 3, larger bubble can gather measuring tube 3 top, there will not be a large amount of bubble coalescence on ultrasonic transducer 5 surface, and cause hyperacoustic travel-time to occur the phenomenon of deviation, ensure that measurement result is unaffected.
In addition, compared with prior art, after ultrasonic transducer 5 being arranged on the side of measuring tube 3, comprise: the measurement mechanism of the parts such as measuring tube 3, gauge outfit 1, watchcase 2, ultrasonic transducer 5, its whole height diminishes, and the space taken during installation is less, even if also can install and use in the place of pipeline distribution comparatively dense, save space, applied range.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
