Description
Technical field
The utility model relates to a kind of precession vortex flowmeter, is specifically related to a kind of precession vortex flowmeter of integral structure.
Background technology
Energy supply not only exists in the daily life, and also be very important in commercial production, traditional human metering mode will change to the robotization mode, and traditional measuring instrument will be substituted by advanced, efficient more, intelligentized technical products, thereby the robotization and the systematized management that realize energy supply are inexorable trends.Fluids such as the rock gas in industries such as oil, chemical industry, iron and steel, metallurgy, electric power, light industry, environmental protection and urban construction, coal gas, pressurized air, oxygen, carbon dioxide and other chemical medium, all need fluid (liquid state or gaseous state) is wherein measured, determine parameters such as its flowing velocity, temperature, pressure, flow, so that control and accurately grasp.Chinese patent 200720124971.2 discloses a kind of integral intelligent vortex precession flowmeter, it is characterized in that: in the gauging table body, be provided with pressure transducer and temperature sensor, on the gauging table body, support is set, the flow rate calculation instrument is set on the support, and pressure transducer and temperature sensor are electrically connected with the flow rate calculation instrument through lead respectively.This product can directly be measured parameters such as the instantaneous delivery, integrated flux, pressure, temperature of measured medium.And pressure, temperature factor compensated calculating automatically, but its poor anti jamming capability, measuring accuracy is because undesired signal former thereby reduce.
The utility model content
The technical problems to be solved in the utility model is: provide that a kind of antijamming capability is strong, the intelligent precession vortex flowmeter of stable performance.
The technical scheme that the utility model adopted is: a kind of intelligent vortex precession flowmeter, comprise gauging table body, power supply, in the gauging table body, be provided with pressure transducer and temperature sensor, on the gauging table body, support is set, flow measurement instrument is set on the support, pressure transducer and temperature sensor are electrically connected with flow measurement instrument by lead respectively, it is characterized in that: also be provided with the pulse signal phase comparator; Described pressure transducer comprises two piezoelectric sensors that are provided with about rotational symmetry in the gauging table body, and described two piezoelectric sensors are electrically connected the pulse signal phase comparator, and the pulse signal phase comparator is electrically connected flow measurement instrument.
Adopt the technique scheme vortex precession flowmeter compared with prior art, owing to be provided with the pulse signal phase comparator, 180 ° of the pressure signal phase differential that two piezoelectric sensors that are provided with about rotational symmetry in the gauging table body transmit, be reinforced through relatively later pressure signal amplitude, and undesired signal is because its two paths of signals phase place is identical, through being attenuated after relatively, pressure, temperature and the flow velocity of fluid are accurately measured in the therefore influence that can exclude the interference signal compared to existing technology.
Further, for saving the energy, described power supply power supply mode is: flow measurement instrument, frequency are amplified plate, temperature, pressure test section, working current is respectively 0.3mA, 0.2mA, 1.5mA, the every 4s work of flow measurement instrument once, working time＜1s enters park mode when not working, the dormancy after-current is 0.01mA; Temperature, pressure test section intermission power supply method, every 10s works once, working time＜0.2s.The working current of flow measurement part has only tens microamperes, uses once the joint lithium battery and can work more than 3 years.The power supply difficulty being provided, can't providing working power maybe need reduce because of outage can't to measure the application scenario of bringing economic loss, is one well to select.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the longitudinal sectional drawing of the utility model vortex precession flowmeter;
Embodiment
Vortex precession flowmeter of the present utility model comprises gauge outfit 1, lead-in wire mouth 2, piezoelectric sensor 3, temperature sensor 4, table body 5, racemization 6, vortex generation body 7, piezoelectric sensor 8 is in table body 5, be provided with piezoelectric sensor 3 (8), temperature sensor 4, on table body 5 support is set, support links together gauge outfit 1 and table body 5, becomes an integrated flow meter.Pressure transducer 3, temperature sensor 4 piezoelectric sensors 3 (8) are connected with gauge outfit 1 through connecting lead respectively, and the data of its detection are input in the gauge outfit 1, carry out data processing and computing.Piezoelectric sensor 3 wherein, temperature sensor 4, piezoelectric sensor 8 and all be product of the prior art can satisfy separately detection, sensing function.Piezoelectric sensor 3 can test fluid pressure signal, and this pressure signal is input in the gauge outfit 1 through connecting lead; Temperature sensor 4 can test fluid temperature signal, and this temperature signal is input in the gauge outfit 1 through connecting lead; Piezoelectric sensor 8 can detect faint charge signal, this electric signal is input in the gauge outfit 1 through connecting lead, gauge outfit 1 is microprocessor of the prior art and display screen, be intelligent, has the Intelligent treatment chip, can handle the data of importing in it according to setting program, can calculate or directly demonstrate the parameter such as instantaneous velocity, pressure, temperature of detected fluid medium; And the factor of pressure, temperature, flow velocity carried out the automatic tracking and compensating computing.Piezoelectric sensor 3 (8) is about rotational symmetry setting in the gauging table body, 180 ° of the pressure signal phase differential of its transmission, be reinforced through relatively later pressure signal amplitude, and undesired signal is because its two paths of signals phase place is identical, after relatively, be attenuated, pressure, temperature and the flow velocity of fluid are accurately measured in the influence that therefore can exclude the interference signal compared to existing technology.The circuit of the present utility model powered battery of 3.6V 16Ah, three parts that power consumption is bigger on the circuit board are as follows: MCU, frequency are amplified plate, temperature, pressure test section, working current is respectively 0.3mA, 0.2mA, 1.5mA, the every 4s work of MCU once, working time＜1s, enter park mode when not working, the dormancy after-current is 0.01mA; Temperature, pressure test section intermission power supply method, every 10s works once, and working time＜0.2s adds other parts IC power consumption, and the complete machine average power consumption is about 0.5mA (1.8mW).
Above embodiment only illustrates concrete application of the present utility model; can not be interpreted as qualification to the utility model protection domain; so long as employing the technical solution of the utility model; perhaps only be to change or distortion, all fall among the protection domain of the present utility model by the routine that those of ordinary skill in the art can both make.
