Abstract
The utility model discloses an ultrasonic large-caliber reflection type water meter. A large-caliber water flow measurement channel is formed in the meter body, a first stainless steel refection column and a second stainless steel reflection column are arranged at the two ends of the lower portion of the large-caliber water flow measurement channel respectively, a first ultrasonic transducer and a second ultrasonic transducer are correspondingly arranged at the two ends of the upper portion of the large-caliber water flow measurement channel respectively, a meter head shell is arranged at the upper end of the meter body, a circuit board, a battery and a liquid crystal display are arranged in the meter head shell, a meter head face cover is arranged at the upper end of the meter head shell and fixed through a meter head end cover, the first ultrasonic transducer is connected with the liquid crystal display through a first transducer lead, and the second ultrasonic transducer is connected with the liquid crystal display through a second transducer lead. The ultrasonic large-caliber reflection type water meter has the advantages that the traditional ultrasonic counter-transmitting type is changed into the reflection type, and a reflection mechanism is directly inlaid in the water meter shell through stainless steel. The ultrasonic large-caliber reflection type water meter has the advantages of being simple and reliable in structure, little in water wave influences and higher in measurement accuracy.
Description
Technical field
The utility model relates to water meter, relates in particular to the reflective water meter of a kind of ultrasound wave heavy caliber.
background technology
Existing heavy caliber ultrasonic water meter or flowmeter, great majority adopt the sensing mode of correlation, but to the table tool below 100mm bore, the detection of correlation distance is too short, and sampling signal resolution is out low, causes the poor stability of table, and measuring accuracy is not high.
summary of the invention
The purpose of this utility model is in order to overcome existing ultrasonic water meter, especially its detection distance of the table tool below 100mm bore is short, and sampled signal resolution is low, causes the poor stability of table tool, the problem that measuring accuracy is not high, provides a kind of ultrasound wave heavy caliber reflective water meter.
The reflective water meter of ultrasound wave heavy caliber comprises gauge outfit end cap, wiring board, the first transducer lead-in wire, the first ultrasonic transducer, the first stainless steel reflection post, table body, the second stainless steel reflection post, the second ultrasonic transducer, the second transducer lead-in wire, gauge outfit shell, battery, liquid crystal display, gauge outfit face shield;
In table body, be provided with heavy caliber water flow measurement passage, two ends, heavy caliber water water flow measurement passage bottom are respectively equipped with the first stainless steel reflection post, the second stainless steel reflection post, heavy caliber water water flow measurement passage both upper ends thereof respectively correspondence is provided with the first ultrasonic transducer, the second ultrasonic transducer, table body upper end is provided with gauge outfit shell, in gauge outfit shell, be provided with wiring board, battery, liquid crystal display, gauge outfit shell upper end is provided with gauge outfit face shield and fixes by gauge outfit end cap, the first ultrasonic transducer is connected with liquid crystal display by the first transducer lead-in wire, the second ultrasonic transducer is connected with liquid crystal display by the second transducer lead-in wire.
The beneficial effects of the utility model are conventional ultrasonic wave correlation to be made into reflective, and reflecting mechanism is to be directly embedded on water meter case with stainless steel, and its advantage is simple and reliable for structure, and little on water wave impact, measuring accuracy is higher.
accompanying drawing explanation
Fig. 1 is the structural representation of the reflective water meter of ultrasound wave heavy caliber.
Embodiment
As shown in Figure 1, the reflective water meter of ultrasound wave heavy caliber comprises gauge outfit end cap 1, wiring board 2, first transducer lead-in wire the 3, first ultrasonic transducer 4, the first stainless steel reflection post 5, table body 6, the second stainless steel reflection post 7, the second ultrasonic transducer 8, the second transducer lead-in wire 9, gauge outfit shell 10, battery 11, liquid crystal display 12, gauge outfit face shield 13;
In table body 6, be provided with heavy caliber water flow measurement passage, two ends, heavy caliber water water flow measurement passage bottom are respectively equipped with the first stainless steel reflection post 5, the second stainless steel reflection post 7, heavy caliber water water flow measurement passage both upper ends thereof respectively correspondence is provided with the first ultrasonic transducer 4, the second ultrasonic transducer 8, table body 6 upper ends are provided with gauge outfit shell 10, in gauge outfit shell 10, be provided with wiring board 2, battery 11, liquid crystal display 12, gauge outfit shell 10 upper ends are provided with gauge outfit face shield 13 fixing by gauge outfit end cap 1, the first ultrasonic transducer 4 is connected with liquid crystal display 12 by the first transducer lead-in wire 3, the second ultrasonic transducer 8 is connected with liquid crystal display 12 by the second transducer lead-in wire 9.
Principle of the present utility model is: by the first ultrasonic transducer 4 and the second ultrasonic transducer 8, convert electric energy to sound wave, also can convert sound wave energy to electric energy; When water meter inside has current out-of-date, the first ultrasonic transducer 4 sends acoustic wave energy, through pillar top, become the first stainless steel reflection post 5 at 45 degree oblique angles to reflex to the second stainless steel reflection post 7 that pillar top becomes 45 degree oblique angles, by the second stainless steel reflection post 7, reflex to the second ultrasonic transducer 8 and convert electric signal to, by interlock circuit and program, calculate, draw adverse current time difference t1; By the second ultrasonic transducer 8, send acoustic wave energy again, through the second stainless steel reflection post 7, reflex to the first stainless steel reflection post 5, by the first stainless steel reflection post 5, reflex to the first ultrasonic transducer 4 and convert electric signal to, by interlock circuit and program, calculate, draw following current time difference t2, complete above after two flow processs, just can obtain the flow velocity of water outlet, i.e. △ t=t1-t2.
