Water meter.Ultrasonic water meter is generated when time and tide is propagated in water because speed changes by detection ultrasonic wave acoustic beam
The time difference, analysis handle water outlet flow velocity to further integrating water outlet flow a kind of new-type water meter, due to its range ratio
Width, the high the operation is stable of measurement accuracy and it is very popular.
Existing ultrasonic water meter is divided into correlation and reflective according to the arrangement of sound channel.Correlation type ultrasonic water meter
Ultrasonic direction of wave travel intersect with water (flow) direction angled, output signal is small, structure is complicated, at high cost.It is reflective super
Sound wave water meter is reflected ultrasonic wave by reflector plate can weaken ultrasonic energy, and reflecting element weaken vulnerable to sediment incrustation it is super
Acoustic wave energy, and ultrasonic water meter is measured using single channel, is got over hour in water flow, measuring accuracy is lower.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of ultrasonic water meters.
In order to solve the above technical problems, one technical scheme adopted by the invention is that：A kind of ultrasonic water meter is provided, including
Table body, the first ultrasonic transducer, the second ultrasonic transducer and controller, the table body include water inlet flow channel, measurement runner,
Outlet passage connects the water inlet flow channel and measures the first runner of runner and connect the outlet passage and measure runner
Second flow channel, the water inlet flow channel and outlet passage are located on same axis, the measurement runner be located at the water inlet flow channel and
Above outlet passage, the water inlet flow channel, measurement runner, outlet passage, first runner and second flow channel are same cross-sectional
Runner, first ultrasonic transducer and second ultrasonic transducer are respectively arranged on the table at the both ends of the measurement runner
On body, first ultrasonic transducer and second ultrasonic transducer are electrically connected and send and receive with the controller
Ultrasonic wave, the measurement runner are made of the first measurement pipeline and the second measurement pipeline, and the flow of the first measurement pipeline is small
The lower section that the flow and the first measurement pipeline for measuring pipeline in described second measure pipeline positioned at described second, described first
It measures and is equipped with the first electrically-controlled valve in pipeline, be equipped with the second electrically-controlled valve, first electrically-controlled valve and institute in the second measurement pipeline
The second electrically-controlled valve is stated to be electrically connected with the controller；The controller is used to that it is automatically controlled to open described first in water flow hour
Valve simultaneously closes off second electrically-controlled valve, and when water flow is big, opens second electrically-controlled valve and simultaneously closes off described the
One electrically-controlled valve.
It is in contrast to the prior art, the beneficial effects of the invention are as follows：It measures runner and is set to water inlet flow channel and out water flow
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 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 ultrasonic water meter of the embodiment of the present invention referring to Fig. 1.The ultrasonic water meter of the present embodiment includes
Table body 1, the first ultrasonic transducer 2, the second ultrasonic transducer 3 and 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 respectively arranged on the table body 1 at the both ends of measurement runner 12
On, the first ultrasonic transducer 2 and the second ultrasonic transducer 3 are 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
