On the original basis, a plurality of signal output connectors are additionally arranged, a plurality of parameter change conditions can be shown in an intuitive mode, and accuracy of measurement is improved. Due to the adoption of the advanced micro power high and new technology, the precession vortex flowmeter can operate for a long time by relying on a battery and can operate when a power supply directly supplies power for the precession vortex flowmeter, and stability of equipment operation is improved. Automatic compensation can be conducted on the temperature and the pressure, and the precession vortex flowmeter can directly detect the standard volume flow rate of gas and the quality flow of saturated steam.
Description
Technical field
The utility model relates to the flow measurement field, relates in particular to a kind of vortex precession flowmeter of low in energy consumption, superior performance.
Background technology
Flow measurement is the science of research material quantitative change, and there is the problem of flow measurement in all places that need grasp quantitative change.At oil, chemical industry, iron and steel, metallurgical, electric power, industries such as light industry all can relate to rock gas, fluids such as general gas and saturated vapour, need measure these fluids, determine flowing velocity, temperature, pressure, parameters such as flow, so that control and accurately grasp, vortex precession flowmeter is the first-selected product of present domestic fluid metering, the structure more complicated of existing similar vortex precession flowmeter, not compact, owing to can not the temperature and pressure of detected medium be compensated automatically, therefore need change volumetric flow rate data under the status of criterion that needing just can obtain to the data that detect, though Overall Power Consumption is low, but rely on the just long-time running of interior battery, but this single power supply can not make the operation of equipment be ensured completely, and vortex precession flowmeter need have the people often it to be safeguarded when long-term work, has strengthened staff's workload.
Summary of the invention
According to above technical matters, it is a kind of low in energy consumption that the utility model provides, the vortex precession flowmeter of superior performance, by the precession vortex flow sensor, flow integrator, temperature sensor and pressure transducer four big parts are formed, it is characterized in that: described precession vortex flow sensor comprises housing, except revolving rectifier, vortex generation body, vortex detector, support, described flow integrator comprises display, output interface, the inside of described housing is the Venturi tube structure, the front end of described housing is provided with vortex generation body, the rear end is provided with except revolving rectifier, the sidewall of described housing is provided with the temperature detection interface, pressure detection interface and vortex detect interface, be connected with temperature sensor respectively, pressure transducer and vortex detector, described housing is provided with support, on the described support display is installed, described display is provided with output interface, described support links together display and housing, described pressure transducer, temperature sensor, vortex detector is connected with the display input end by connecting lead, forms an integrated flow meter.
The beneficial effects of the utility model are: the utility model has increased communication output, electric current output, pulse signal output on original basis, the change curve of exportable parameter, and the situation of change of display parameter has improved the accuracy of measuring intuitively; Adopt advanced little power consumption new and high technology, Overall Power Consumption is low, can improve operation stability of equipment by the power supply powered operation again with the long-term powered operation of internal battery; Adopt advanced microcomputer technology and high performance integrated chip, complete machine is powerful, superior performance; Can and compensate automatically the temperature and the pressure that detect medium, can directly detect the standard volume flow of gas or the mass rate of saturated vapour; Non mechanical movable is difficult for burn into fiduciary level height, good stability, and long-term work need not be safeguarded.

Embodiment
In conjunction with Fig. 1, shown in Figure 2, the utility model is further specified:
The utility model comprises housing 1, except revolving rectifier 2, vortex generation body 3, vortex detector 4, support 5, display 6, output interface 7, temperature sensor 8, pressure transducer 9, the inside of housing 1 is the Venturi tube structure, vortex generation body 3 is installed in the front end of housing 1, to be installed in the rear end of housing 1 except revolving rectifier 2, temperature sensor 8, pressure transducer 9 and vortex detector 4 are connected respectively to the temperature detection interface on the housing sidewall, pressure detection interface and vortex detect interface, again support 5 is installed on the housing 1, display 6 is installed above the support 5, display 6 is provided with output interface 7, temperature sensor 8, pressure transducer 9, vortex detector 4 is connected with the signal input part of display 6 by connecting lead, forms an integrated flow meter.
The housing 1 of vortex precession flowmeter is put into measured fluid fully, when fluid enters the flow sensor entrance along axia flow, vortex generation body 3 forces fluid to be rotated motion, produce bumpy flow at vortex generation body center, bumpy flow is precession in Venturi tube, arriving the unexpected throttling of contraction section accelerates bumpy flow, after bumpy flow enters diffuser, because forcing, the effect that refluxes carries out the rotation of screw type secondary, the gyro frequency of bumpy flow is directly proportional with velocity of medium and is linearity at this moment, the faint charge signal that is detected by vortex detector 4, be exaggerated by prime amplifier, filtering, shaping, become the pulse signal that frequency is directly proportional with flow velocity relatively, send into flow integrator and count processing, when eddy-currents during through temperature sensor 8 and pressure transducer 9, detected signal will be admitted to the signal amplifying part branch and amplify separately, frequency signal after the amplification compares through comparer again, comparer will be exported the pulse signal that is directly proportional with flow velocity, send into integrating instrument again and count, data after treatment show at display 6.
