Description
Technical field
The invention belongs to acoustics, intelligence instrument field, in particular with ultrasonic detecting technology, specifically a kind of spiral ultrasonic flow sensor.
Background technology
Ultrasonic flow sensor is propagated in the fluid of flowing using ultrasonic wave, by receiving and analyzing through the contained information of the ultrasonic wave of fluid, to detect the flow velocity of fluid, so as to be converted into flow.Information characteristic according to detection is different, can be divided into propagation speed differential method, Doppler method, beam deviation method, Noise Method and correlation method etc..
The ultrasonic wave of existing ultrasonic flow sensor propagation path in a fluid, it is general to have straight line to penetrating and secondary reflection, the Shi Biaoti centers flow velocity that both paths measure, during actual installation use, the length of front and rear straight tube, upstream and downstream valve elbow and ductwork pressure change etc. can produce turbulent influence, now can there is large change in the ratio between Biao Ti centers flow velocity and pipeline actual flow velocity, therefore its flow measurement precision and repeatability need to be improved.
The content of the invention
It is an object of the invention to provide a kind of spiral ultrasonic flow sensor, its ultrasonic wave propagation path covering whole table body inner hole section, to obtain the information of more complete table body actual flow velocity, effectively improves flow measurement precision and repeatability.
The technical scheme is that：
A kind of spiral ultrasonic flow sensor, including table body and reflection unit, wall circumferentially uniform four reflection units in table body, four reflection units are each at a certain angle, ultrasonic signal sends from one end transducer and is reflected on four reflection units successively, finally enters other end transducer.
The beneficial effects of the invention are as follows：
A kind of spiral ultrasonic flow sensor is provided, its ultrasonic wave propagation path covers whole table body inner hole section, the information of more complete table body actual flow velocity can be obtained, effectively improve flow measurement precision and repeatability.
