Description
Technical field
The invention belongs to acoustics, field of sensing technologies, particularly ultrasonic detection technology, specifically a kind of inserted-link type ultrasonic flow sensor structure.
Background technology
Existing ultrasonic flow sensor, the general fluid flow detection carried out using speed difference method in pipeline, i.e. using the ultrasonic wave time difference that concurrent-countercurrent is propagated in liquid, so as to calculate the flowing velocity of liquid, therefore, effective measurement distance of ultrasonic wave, determines the measurement performance of ultrasonic flow sensor.
In order to ensure sufficiently long effective measurement distance, in design discharge sensor, people try one's best makes the measurement pipeline of sensor keep having identical caliber and shape with pipe network, but by sensor pipeline section（1.1）The limitation of length, particularly bigbore sensor, its flange（1.3）Structure limits transducer（1.2）Setting angle, cause effective measurement distance L1 of ultrasonic wave shorter, certainty of measurement and repeatability is improved.
The content of the invention
The present invention is to overcome drawbacks described above, there is provided the ultrasonic flow sensor structure that a kind of assembling is simple, effective measurement distance is longer.
The technical scheme is that：
A kind of inserted-link type ultrasonic flow sensor structure, including pipeline section（2.1）, transducer inserted link（2.2）.The transducer inserted link（2.2）, for loading ultrasonic transducer（2.2.1）, can be according to pipeline section bore and precision the need for, in same transducer inserted link（2.2）Upper one or more ultrasonic transducers of loading（2.2.1）.
The pipeline section（2.1）On have vertical hole（2.1.1）, for inserting transducer inserted link（2.2）, because vertical hole is vertical with pipeline section axis, therefore the effective measurement distance L1 of ultrasonic wave of maximum can be ensured.
The beneficial effects of the invention are as follows：Assembling is simple, and effective measurement distance is longer, and the certainty of measurement and repeatability of flow are higher.
