Abstract
The invention relates to a structure of an ultrasonic flow sensor, which comprises a sensor pipeline section (2.1), vertical holes (2.1.1), transducer insert rods (2.2) and transducers (2.2.1), wherein the two pairs of the vertical holes (2.1.1) are formed in the sensor pipeline section (2.1); the vertical holes that are formed in pairs are respectively positioned on both sides of the sensor pipeline section (2.1); the transducer insert rods (2.2) are vertically inserted in the vertical holes (2.1.1); and the two transducers (2.2.1) are arranged in the same transducer insert rod. Through the adoption of the ultrasonic flow sensor, the characteristics of simple assembly and high measuring accuracy are achieved.
Description
Technical field
The invention belongs to acoustics, field of sensing technologies, particularly ultrasonic detection technology, specifically is a kind of structure of ultrasonic flow sensor.
Background technology
Existing ultrasonic flow sensor; The general fluid flow that adopts the velocity contrast method to carry out in the pipeline detects; Promptly utilize the ultrasound wave mistiming that concurrent-countercurrent is propagated in liquid, thereby calculate the flowing velocity of liquid, therefore; Hyperacoustic effective propagation distance and flowing field stability have determined the measurement performance of ultrasonic flow sensor.
In order to guarantee flowing field stability, when the design discharge sensor, people make the measuring channel of sensor keep with pipe network identical caliber and shape being arranged as far as possible; Structure such as Fig. 1 show; The transducer inserted link passes measuring channel sideling, and transducer is arranged on the two ends of transducer inserted link, and this structure is owing to receive the restriction of sensor pipeline section (2.1) length; Particularly bigbore sensor; Its flange (1.3) structural limitations the setting angle of transducer (2.2.1), cause hyperacoustic effective propagation distance L1 shorter, final measuring accuracy is always barely satisfactory.
Summary of the invention
The object of the invention, for overcoming above-mentioned defective, provide a kind of easy for installation, measure accurate ultrasonic flow sensor.
For realizing the foregoing invention purpose, adopt following structure:
A kind of ultrasonic flow sensor comprises sensor pipeline section 2.1, upright hole 2.1.1; Transducer inserted link 2.2; Transducer 2.2.1 is provided with upright hole 2.1.1 in pairs on the said sensor pipeline section 2.1, the upright hole 2.1.1 that is provided with in pairs lays respectively at the both sides of sensor pipeline section 2.1; The 2.2 vertical insertions of transducer inserted link are stood among the 2.1.1 of hole, and one or more transducers 2.2.1 packs on same transducer inserted link 2.2.Because therefore upright hole and pipeline section axis normal can guarantee the maximum effective propagation distance L1 of ultrasound wave, have also guaranteed the stability in flow field simultaneously.
Upright hole 2.1.1 will be provided with in pairs, and number can be even numbers such as 2,4,6,8.
The vertical insertion of transducer inserted link is stood in the hole, also paired setting, and transducer is arranged on the transducer inserted link, also is provided with in pairs, and is corresponding each other, plays transmitting and receiving action of ultrasonic waves respectively.The number of transducer can be one, or a plurality of.
Described ultrasonic flow sensor, the number that preferred scheme is described upright hole 2.1.1 is four.
Described ultrasonic flow sensor, the number that preferred scheme is described transducer 2.2.1 is two.
The invention has the beneficial effects as follows: assembling is simple, and measuring accuracy is high.
