Its basic principle is the flow velocity that fluid in a certain pipeline section is measured using ultrasonic transducer, so that it is determined that the flow of fluid.
In pipeline section, a ultrasonic transducer can be set, emit and receive its back wave；Or it is opposite super with two
Acoustic wave transducer, a transmitting signal, another receives signal.
In the case where length of pipe section is certain, with according to time difference method measuring principle, effective sound path is longer, the identical situation of flow velocity
The lower time difference is bigger, and measurement data is more accurate.
The setting of ultrasonic transducer in current flux meter pipeline section, is generally orthogonal to pipeline section axis and is installed, and surpasses
Acoustic wave transducer will be visited in the middle of pipeline section, and the measurement distance of ultrasonic transducer is shorter and there is interference to fluid, therefore,
The accuracy that it is measured is poor.
Summary of the invention
The purpose of this utility model is that: design a kind of meter spool piece that can be improved measurement accuracy.
Pipeline section of the utility model itself includes the main leg with energy converter mounting hole, technical solution are as follows: described to change
Energy device mounting hole is tilted by outer and introversive adjacent pipeline section nozzle.This mounting means of the utility model, in length of pipe section one
Fixed situation is big, increases effective sound path as best one can, to improve the accuracy of measurement.
For the utility model, generally there are two types of forms, and one is nearby install ultrasonic transducer using nozzle at one end
Group, each ultrasonic transducer group have at least one ultrasonic transducer.This group of ultrasonic transducer emits signal, and through reflecting
Afterwards, which receives signal again.At this point, only being improved to the mounting hole of the ultrasonic transducer group.Separately
One kind is that installation emits the ultrasonic transducer group of signal and receives the super of signal respectively at the nozzle close to two main legs
Acoustic wave transducer group.At this point, then needing to be all provided at two port in main leg to achieve the effect that increase effective sound path
Energy converter mounting hole is set, i.e., has water inlet end energy converter mounting hole group and water outlet energy converter mounting hole group on the main leg,
Each energy converter mounting hole group includes at least one energy converter mounting hole, and two groups of energy converter mounting holes are by outer and introversive adjacent pipe
Section nozzle inclination；The axis of two groups of energy converter mounting holes is parallel.
The movement of fluid is influenced to prevent ultrasonic transducer after mounting, measurement is had an impact, preferably by its end
It is set under main leg's inner wall, i.e., is had and energy converter mounting hole on corresponding pipe segment inner surface at energy converter mounting hole inner end
Vertical slot.
The angle of energy converter mounting hole and main leg's axis is typically designed as 50 ° ~ 85 ° in the utility model.
Main leg has ultrasonic transducer position limiting structure, to guarantee the accuracy of ultrasonic transducer installation site.
The utility model after ultrasonic transducer is installed, including main leg and the ultrasonic waves being mounted on main leg
Can device, the ultrasonic transducer from outer and interior installation direction to the adjacent nozzle of main leg at tilt.
Description as the utility model to pipeline section itself, ultrasonic transducer are to be mounted on master by energy converter mounting hole
On pipeline section, energy converter mounting hole is generally required to be tilted by outer and introversive adjacent pipeline section nozzle at this time, ultrasonic transducer is in L
Shape, and loaded in energy converter mounting hole.
To guarantee that ultrasonic transducer is mounted on accurate location, limited position mechanism, ultrasonic wave transducer are set on main leg
Device and position-limit mechanism cooperate.
The beneficial effects of the utility model are: passing through setting again to the ultrasonic transducer setting angle on main leg
Meter, increases effective sound path, meanwhile, influence of the ultrasonic transducer to fluid is sufficiently reduced, is surveyed so as to effectively improve
The accuracy of amount.
