Abstract
The utility model relates to an ultrasonic wave flow sensor for measuring the flow capacity of big pipe diameter fluid, in particular to a directly-inserted ultrasonic wave sensor. The technical solution is that the ultrasonic wave flow sensor comprises a pipeline (1), an upstream sensor (2) and a downstream sensor (3), wherein the upstream sensor and the downstream sensor are vertically insertedin the pipeline (1), and the depths of the two sensors which are inserted in the pipeline are consistent, thereby leading the centers of receiving surfaces (5) of the two sensors to be on the same straight line, and sounding surfaces (4) of the two sensors are opposite. The shaft line mounting distances of the two sensors are assured according to measured fluid. The ultrasonic wave flow sensor hasthe advantages that since the depths of the two sensors which are inserted in the pipeline are consistent, the centers of receiving surfaces (5) of the two sensors are led to be on the same straightline, the sounding surfaces are opposite, ultrasonic wave acoustic range can not be influenced by a measured pipe diameter, and the problem of use limitation of an existing ultrasonic wave sensor is solved.

The utility model purpose provides a kind of ultrasonic flow sensor, can not impact pipeline inner fluid fluidised form, and its sound path also can not be subjected to the restriction of caliber, guarantees to measure accurately, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: ultrasonic flow sensor comprises pipeline, upstream sensor, downstream sensor, upstream sensor and downstream sensor are separately positioned on the upstream and downstream of pipeline, pipeline between upstream sensor and the downstream sensor is made up of three parts, the centre is one section rectilinear duct, be parallel to the sensor pipe laying, the two ends of rectilinear duct are respectively two sections oblique line pipelines, mate mutually at angle of inclination between two sections oblique line pipelines and the rectilinear duct, two sensors are separately positioned on two sections corresponding positions of oblique line pipeline, the inner tubal wall of oblique line pipeline section is provided with the reflecting surface of sensor, with the corresponding coupling of the sounding face of sensor.
Inclination angle between said oblique line pipeline and the rectilinear duct is 45 degree.
Said sensor reflecting surface is exactly the inwall of oblique line pipeline, inner wall smooth can become reflecting surface, the ultrasound wave that upstream sensor sends, through corresponding with it upstream sensor reflecting surface reflection, after rectilinear duct, arrive the downstream sensor reflecting surface, reflex to downstream sensor again, sound path can not be subjected to the restriction of caliber.
Two outsides of ultrasonic sensor in pipeline are consistent with inner-walls of duct, can not impact pipeline inner fluid fluidised form.
The beneficial effects of the utility model are: ultrasonic signal is after upstream sensor takes place, two secondary reflections in pipeline are received by the downstream ultrasonic sensor, can not impact pipeline inner fluid fluidised form, its sound path can not be subjected to the restriction of caliber again, guarantees the accuracy of measuring.
