Description
Technical field
The present invention relates to water meter technical field, particularly relate to a kind of ultrasonic water meter.
Background technology
As everyone knows, in order to save water source, controlling artificial waste water resource, usually on the water inlet pipe of each household, tap water meter being installed.Ultrasonic water meter is the time difference produced because speed changes when time and tide is propagated in water by detecting ultrasonic wave acoustic beam, analyzing and processing obtains the new-type water meter of one of the flow velocity of water outlet thus the flow of integrating water outlet further, because its range ratio is wide, measuring accuracy high workload is stable and very popular.
Existing ultrasonic water meter is divided into correlation and reflective according to the arrangement of sound channel.The ultrasonic propagation direction of correlation type ultrasonic water meter and water (flow) direction are crossed as certain angle, output signal little, complex structure, cost are high.Reflecting type ultrasonic water meter can weaken ultrasonic energy by reflectors reflects ultrasound wave, and reflecting element is subject to sediment incrustation and weakens ultrasonic energy, and ultrasonic water meter adopts single channel to measure, and at water flow more hour, measuring accuracy is lower.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of ultrasonic water meter.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of ultrasonic water meter, comprise table body, first ultrasonic transducer, second ultrasonic transducer and controller, described table body comprises water inlet flow channel, measure runner, outlet passage, connect described water inlet flow channel and measure the first flow of runner and be connected the second runner of described outlet passage and measurement runner, described water inlet flow channel and outlet passage are positioned on same axis, described measurement runner is positioned at above described water inlet flow channel and outlet passage, described water inlet flow channel, measure runner, outlet passage, first flow and the second runner are the runner of same cross-sectional, described first ultrasonic transducer and described second ultrasonic transducer are located on the table body at the two ends of described measurement runner respectively, described first ultrasonic transducer and described second ultrasonic transducer are electrically connected with described controller and send and receive ultrasound wave, described measurement runner is made up of the first measuring channel and the second measuring channel, the flow of described first measuring channel is less than the flow of described second measuring channel and described first measuring channel is positioned at the below of described second measuring channel, the first electrically-controlled valve is provided with in described first measuring channel, the second electrically-controlled valve is provided with in described second measuring channel, described first electrically-controlled valve and described second electrically-controlled valve are electrically connected with described controller, described controller is used at water flow hour, opens described first electrically-controlled valve and closes described second electrically-controlled valve simultaneously, and when water flow is large, opens described second electrically-controlled valve and close described first electrically-controlled valve simultaneously.
Be different from the situation of prior art, the invention has the beneficial effects as follows: measure runner and be located at above water inlet flow channel and outlet passage, so ultrasonic signal is strong and stable, and ultrasonic transducer is not easy sediment incrustation at the highest point of current, and measure runner to be made up of two measuring channels, a flow is little, and a flow is large, no matter so discharge amount is large or little, measuring accuracy is all higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention ultrasonic water meter.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the structural representation of embodiment of the present invention ultrasonic water meter.The ultrasonic water meter of the present embodiment comprises table body 1, first ultrasonic transducer 2, second ultrasonic transducer 3 and controller (figure does not illustrate).
Table body 1 comprises water inlet flow channel 11, measurement runner 12, outlet passage 13, connects water inlet flow channel 11 and measure the first flow 14 of runner 12 and be connected the second runner 15 of outlet passage 13 and measurement runner 12, water inlet flow channel 11 and outlet passage 13 are positioned on same axis, measuring runner 12 is positioned at above water inlet flow channel 11 and outlet passage 13, and water inlet flow channel 11, measurement runner 12, outlet passage 13, first flow 14 and the second runner 15 are the runner of same cross-sectional.
First ultrasonic transducer 2 and the second ultrasonic transducer 3 are located on the table body 1 at the two ends measuring runner 12 respectively, and the first ultrasonic transducer 2 and the second ultrasonic transducer 3 are electrically connected with controller and send and receive ultrasound wave.
Measure runner 12 to be made up of the first measuring channel 121 and the second measuring channel 122, the flow of the first measuring channel 121 is less than the flow of the second measuring channel 122 and the first measuring channel 121 is positioned at the below of the second measuring channel 122.Be provided with in first measuring channel 121 in first electrically-controlled valve 4, second measuring channel 122 and be provided with the second electrically-controlled valve 5, first electrically-controlled valve 4 and the second electrically-controlled valve 5 is electrically connected with controller.
Controller is used at water flow hour, opens the first electrically-controlled valve 4 and closes the second electrically-controlled valve 5 simultaneously, and when water flow is large, opens the second electrically-controlled valve 5 and close the first electrically-controlled valve 4 simultaneously.
The ultrasonic water meter of the present embodiment operationally, current enter from water inlet flow channel 11, upwards by first flow 14, enter again and measure runner 12, under measurement runner 12 is backward, enters the second runner 15, then is flowed out by outlet passage 13, namely the flow direction of current is first levels, again upwards, again level, downwards, final level, track of stream forms " convex " shape.At measurement runner 12, if water flow is little, controller opens first electrically-controlled valve 4 closes the second electrically-controlled valve 5 simultaneously, uses the first measuring channel 121 to carry out the accurate-metering of low discharge; If water flow is large, controller opens second electrically-controlled valve 5 closes the first electrically-controlled valve 4 simultaneously, uses the second measuring channel 122 to carry out the accurate-metering of large discharge.
By the way, the measurement runner of the ultrasonic water meter of the embodiment of the present invention is located at above water inlet flow channel and outlet passage, so ultrasonic signal is strong and stable, and ultrasonic transducer is not easy sediment incrustation at the highest point of current, and measure runner to be made up of two measuring channels, a flow is little, and a flow is large, no matter so discharge amount is large or little, measuring accuracy is all higher.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
