Measure the second flow channel of runner, the water inlet flow channel and outlet passage be located on same axis, the measurement runner described in into
Above water flow passage and outlet passage, the water inlet flow channel, measurement runner, outlet passage, first runner and second flow channel are phase
With the runner in section, water level sensor is equipped in the water inlet flow channel, the water level sensor is electrically connected with the controller, institute
On the table body for stating the both ends that the first ultrasonic transducer and second ultrasonic transducer are respectively arranged on the measurement runner, institute
It states the first ultrasonic transducer and second ultrasonic transducer is electrically connected with the controller and sends and receives ultrasonic wave,
The measurement runner is made of the first measurement pipeline and the second measurement pipeline, and the flow of the first measurement pipeline is less than described the
The flow of two measurement pipelines and the first measurement pipeline are located at the lower section of the second measurement pipeline, the first measurement pipeline
In be equipped with the first electrically-controlled valve, it is described second measurement pipeline in be equipped with the second electrically-controlled valve, first electrically-controlled valve and it is described second electricity
Control valve is electrically connected with the controller；The water level sensor is detecting that current level is lower than for detecting current level
The first signal is sent to the controller when preset water level, and when detecting that current level is higher than the preset water level to institute
It states controller and sends second signal；The controller is used for when receiving first signal, opens first electrically-controlled valve
Second electrically-controlled valve is simultaneously closed off, and when receiving the second signal, opens second electrically-controlled valve and simultaneously close off
First electrically-controlled valve.
It is in contrast to the prior art, the beneficial effects of the present invention are: measurement runner 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 the valve-regulated 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 the valve-regulated ultrasonic water meter of the embodiment of the present invention referring to Fig. 1.The valve-regulated of the present embodiment surpasses
Sound wave water meter 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.Water level is equipped in water inlet flow channel 11 to pass
Sensor 110, water level sensor 110 are electrically connected with the controller.
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
Electrically-controlled valve 5 is electrically connected with the controller.
Wherein, water level sensor 110 is for detecting current level, and when detecting current level lower than preset water level to
Controller sends the first signal, and sends second signal to controller when detecting that current level is higher than preset water level.
Controller is used for when receiving the first signal, is opened the first electrically-controlled valve 4 and is simultaneously closed off the second electrically-controlled valve 5, and
When receiving second signal, opens the second electrically-controlled valve 5 and simultaneously close off the first electrically-controlled valve 4.
At work, water flow enters the valve-regulated ultrasonic water meter of the present embodiment from water inlet flow channel 11, upwardly through first
Runner 14 enters back into measurement runner 12, second flow channel 15 is downwardly into after measuring runner 12, then flow by outlet passage 13
Out, i.e. the flow direction of water flow is first level, then upwards, again it is horizontal, still further below, final level, track of stream forms " convex " shape.
Due to being equipped with water level sensor 110 in water inlet flow channel 11, if current level is lower than preset water level, illustrate water flow stream
Measure it is small, if current level be higher than preset water level, illustrate that water flow is big.And in measurement runner 12, if water flow is small, control
Device processed opens the first electrically-controlled valve 4 and simultaneously closes off the second electrically-controlled valve 5, and the accurate meter of small flow is carried out using the first measurement pipeline 121
Amount；If water flow is big, controller opens the second electrically-controlled valve 5 and simultaneously closes off the first electrically-controlled valve 4, uses the second measurement pipeline
122 carry out the accurate metering of big flow.
By the above-mentioned means, the measurement runner of the valve-regulated ultrasonic water meter of the embodiment of the present invention is set to water inlet flow channel and goes out
Above water flow passage, so ultrasonic signal is strong and stablizes, and ultrasonic transducer is not easy connate water in the highest point of water flow
Dirt, and measure runner and be made of two measurement pipelines, a flow is small, and a flow is big, no matter so water flow amount it is big or
Be it is small, measuring accuracy is higher.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
