Abstract
The utility model relates to a structure of an ultrasonic flow sensor. The ultrasonic flow sensor comprises a sensor tube section (2.1), stand holes (2.1.1), energy converter inserting rods (2.2) and energy converters (2.2.1), wherein the sensor tube section (2.1) is provided with two pairs of stand holes (2.1.1), and the stand holes (2.1.1) arranged in pairs are respectively located on two sides of the sensor tube section (2.1). The energy converter inserting rods (2.2) are vertically inserted into the stand holes (2.1.1), and two energy converters (2.2.1) are arranged on the same energy converter inserting rod (2.2). The ultrasonic flow sensor has the advantages of being simple to assemble and high in measuring accuracy.
Description
Technical field
The utility model belongs to acoustics, field of sensing technologies, particularly ultrasonic detection technology, specifically 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, namely 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, transducer is arranged on the two ends of transducer inserted link, this structure is owing to being subjected to the restriction of sensor pipeline section (2.1) length, bigbore sensor particularly, 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.
The utility model content
The purpose of this utility model, for overcoming defects, provide a kind of easy for installation, measure accurate ultrasonic flow sensor.
For realizing above-mentioned utility model purpose, adopt following structure:
A kind of ultrasonic flow sensor, comprise sensor pipeline section 2.1, vertical hole 2.1.1, transducer inserted link 2.2, transducer 2.2.1 is provided with vertical hole 2.1.1 in pairs on the described sensor pipeline section 2.1, the vertical hole 2.1.1 that arranges in pairs lays respectively at the both sides of sensor pipeline section 2.1, among the vertical vertical hole 2.1.1 of insertions of transducer inserted link 2.2, at same transducer inserted link 2.2 one or more transducers 2.2.1 that packs into.Because vertical hole is vertical with the pipeline section axis, therefore can guarantee the maximum effective propagation distance L1 of ultrasound wave, has also guaranteed the stability in flow field simultaneously.
Vertical hole 2.1.1 will arrange in pairs, and number can be the 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 arranges in pairs, and is mutually corresponding, plays respectively hyperacoustic effect that transmits and receives.The number of transducer can be one, or a plurality of.
Described ultrasonic flow sensor, the number that preferred scheme is described vertical hole 2.1.1 is four.
Described ultrasonic flow sensor, the number that preferred scheme is described transducer 2.2.1 is two.
The beneficial effects of the utility model are: assembling is simple, and measuring accuracy is high.
