Above road, so ultrasonic signal is strong and stablizes, and ultrasonic transducer is not easy sediment incrustation in the highest point of water flow, and
And measurement runner is made of two measurement pipelines, a flow is small, and a flow is big, no matter so water flow amount is big or small,
Measuring accuracy is higher.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of direct-injection type ultrasonic water meter of the embodiment of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiments are merely a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It is the structural schematic diagram of direct-injection type ultrasonic water meter of the embodiment of the present invention referring to Fig. 1.The direct-injection type of the present embodiment is super
Sound wave water meter includes table body 1, the first ultrasonic transducer 2, the second ultrasonic transducer 3, the first turntable 21,31 and of the second turntable
Controller (meaning not shown).
Table body 1 includes water inlet flow channel 11, measurement runner 12, outlet passage 13, connection water inlet flow channel 11 and measurement runner 12
First runner 14 and connection outlet passage 13 and the second flow channel 15 for measuring runner 12, water inlet flow channel 11 and outlet passage 13
On same axis, measurement runner 12 is located at 13 top of water inlet flow channel 11 and outlet passage, water inlet flow channel 11, measurement runner
12, outlet passage 13, first runner 14 and second flow channel 15 are the runner of same cross-sectional.
First ultrasonic transducer 2 and the second ultrasonic transducer 3 are pacified by the first turntable 21 and the second turntable 31 respectively
On the table body 1 at the both ends loaded on measurement runner 12, the first turntable 21 and the second turntable 31 are attached on table body 1 and can rotate,
First turntable 21 and the second turntable 31 are electrically connected with the controller by driving circuit (meaning not shown), the first ultrasonic transducer
2 and second ultrasonic transducer 3 be electrically connected with the controller and send and receive ultrasonic wave.
Measurement runner 12 is made of the first measurement pipeline 121 and the second measurement pipeline 122, the stream of the first measurement pipeline 121
It measures the flow for measuring pipeline 122 less than second and the first measurement pipeline 121 is located at the lower section of the second measurement pipeline 122.First surveys
It is equipped with the first electrically-controlled valve 4 in buret road 121, is equipped with the second electrically-controlled valve 5, the first electrically-controlled valve 4 and second in the second measurement pipeline 122
Electrically-controlled valve 5 is electrically connected with the controller.
Wherein, the first turntable 21 and the second turntable 31 all have first position and the second position, when the first turntable 21 and
When two turntables 31 go to first position, the first ultrasonic transducer 2 and the second ultrasonic transducer 3 distinguish the first measurement pipe of face
The both ends in road 121；When the first turntable 21 and the second turntable 31 go to the second position, the first ultrasonic transducer 2 and the second surpass
