Abstract
The utility model relates to an ultrasonic flow measuring transducer, especially detect the ultrasonic flow measuring transducer of medium (liquid or gaseous) flow in the pipeline. The technical scheme is that the ultrasonic flow measurement sensor comprises a pipeline (1), a pair of transducers (2 and 3) and a pair of reflectors (4 and 5), wherein the two transducers are fixed on the pipeline at a distance, the two reflectors (4 and 5) are arranged in the pipeline at positions corresponding to the two transducers, the reflecting surfaces of the two reflectors form an angle of 45 degrees with the pipeline, and the two reflecting surfaces are matched with each other. When the device is used, the relation between transmission and reception is formed by the reflection of the two transducers through the reflecting surface, and the medium flow of the pipeline can be measured by a speed difference method. The utility model has the characteristics of rational in infrastructure, easily make, measure the accuracy height etc.
Description
The utility model relates to the ultrasonic flow rate survey sensor of medium (liquid or gas) flow in a kind of the ultrasonic flow rate survey sensor, particularly signal piping.
At present, in needs are measured pipeline during medium (liquid or gas) flow, often adopt the ultrasonic flow rate survey sensor to measure, be called " calorimeter ultrasonic flow transducer " as 00207712.4 of Chinese patent, be to be that the main transducer that constitutes inserts at a distance of a segment distance and is placed in the pipeline by piezoelectric ceramic wafer with two, sending ultrasound wave by a transducer transmits in pipeline, another transducer receives, after piezoelectric signal handled, obtain the flow of liquid in the pipeline or gas.The problem that this device exists is: because transducer is inserted in the pipeline, the resistance of media flow is increased, the fluidised form shakiness directly influences accuracy of measurement, and volume is bigger in addition, is difficult for making.
The utility model purpose provides a kind of ultrasonic flow rate survey sensor, reduces the mobile resistance of pipeline medium is improved measuring accuracy, is convenient to make, and solves the problems referred to above that prior art exists.
The technical solution of the utility model is: constitute the ultrasonic flow rate survey sensor by pipeline, a pair of transducer, a pair of reflecting body, transducer is made up of shell, piezoelectric ceramic wafer, output cable, piezoelectric ceramic wafer places in the shell, one end of output cable is connected with piezoelectric ceramic wafer, the other end stretches out shell, two transducers are fixed on the pipeline at a distance of a segment distance, in pipeline, two reflecting bodys are set with two corresponding positions of transducer, the reflecting surface and the pipeline of two reflecting bodys are 45, and two reflectings surface mate mutually.
Adopt the utility model, output cable is connected with known converter, after the ultrasound wave that first transducer sends arrives reflecting body reflecting surface corresponding with it in the pipeline, reflex to again on the reflecting surface of another reflecting body that matches, reflex to again with corresponding another transducer of this reflecting body on receive, vice versa.When pipeline internal medium was below first transducer, there were a time difference in ultrasound wave trace (downbeam) travel-time and flyback (countercurrent direction) travel-time, can measure the pipeline medium flow with " velocity contrast method " by known computing method.Because the reflecting body in the pipeline can manufacture streamlined and volume is very little,, can improve the accuracy of measurement to the basic not influence of flowing of medium.
The utlity model has rational in infrastructure, be easy to characteristics such as manufacturing, measurement accuracy height.
Accompanying drawing is the utility model example structure synoptic diagram.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
In an embodiment, adopt the utility model that the fluid flow in the pipeline is measured, the ultrasonic flow rate survey sensor is by pipeline (1), a pair of transducer (2,3), a pair of reflecting body (4,5) constitute, transducer is by shell (6), piezoelectric ceramic wafer (7), output cable (8) is formed, piezoelectric ceramic wafer places in the shell, one end of output cable is connected with piezoelectric ceramic wafer, the other end stretches out shell, two transducers are fixed on the pipeline at a distance of a segment distance, in pipeline, two reflecting bodys (4 are set with two corresponding positions of transducer, 5), the reflecting surface and the pipeline of two reflecting bodys are 45, and two reflectings surface mate mutually.Output cable output is connected with known converter, after ultrasound wave that first transducer sends arrives in the pipeline with it the reflecting surface of corresponding reflecting body, reflex on the reflecting surface of another reflecting body that matches, reflex to again with corresponding another transducer of this reflecting body on receive, vice versa.
Claims (1)
1, a kind of have a pipeline (1), a pair of transducer (2,3) ultrasonic flow rate survey sensor, transducer is by shell (6), piezoelectric ceramic wafer (7), output cable (8) is formed, piezoelectric ceramic wafer places in the shell, one end of output cable is connected with piezoelectric ceramic wafer, the other end stretches out shell, it is characterized in that two transducers (2,3) be fixed on the pipeline (1) at a distance of a segment distance, in pipeline, two reflecting bodys (4 are set with two corresponding positions of transducer, 5), the reflecting surface and the pipeline of two reflecting bodys are 45, and two reflectings surface mate mutually.
