The technical solution of the utility model: integral intelligent shrinking neck type vortex shedding flow meter, comprise meter body, auxiliary body, support, the intelligent flow-integrating instrument of taking place, meter body medium position is the straight-line segment body, it is characterized in that: forward and backward at the straight-line segment body at middle part, Vickers curve contraction section body and back Vickers curve diffuser body before being provided with respectively, the meter body is made of preceding Vickers curve contraction section body, middle straight line segment body and back Vickers curve diffuser body; At middle straight line segment body place, be provided with force transducer, temperature sensor and pressure transducer, force transducer, temperature sensor and pressure transducer are connected with intelligent flow-integrating instrument respectively by connecting line.
Further feature is: the curve linear of preceding Vickers curve body and back Vickers curve body meets hot this base curves in Victor, and preceding Vickers curve body is hot this base curves contraction section in Victor, and back curve body is hot this base curves diffuser in Victor.
The utility model integral intelligent shrinking neck type flux of vortex street flowmeter with respect to prior art, also has following characteristics:
1, adopts microcomputer chip and software engineering, give instrument powerful intelligent function.Adopt integrated design technology, instrument integrates various input and processing, flow rate calculation and compensation, demonstration and communication.Microcomputer technology, software engineering, the information processing technology, mechanics of communication and integrated design technology are organically merged, represented the direction of modern instrument development.
2, integrate high-precision flow, pressure, temperature sensor and intelligent flow integrating unit, display unit, can measure pressure, temperature and the flow of measured medium.And can carry out automatic tracking and compensating to flow.
3, adopt little power consumption electron device, both can be by a joint 1# lithium battery power supply (need not mains-supplied).Again can be by the external power powered operation.Overall Power Consumption is low.
4, adopt high-performance microprocessor, software function is powerful, and (to temperature, pressure) has zeroing and transfers range function, superior performance.
5, adopt the mechatronics technology well-designed, make flowmeter handsome in appearance generous, compact conformation, non mechanical movable, good stability, the life-span is long.
6, adopt the large-screen lc of high-contrast to show, but justifying demonstrates under the standard state or duty under the strong attitude of instantaneous delivery, pressure, temperature and standard under parameters such as fluid total volume.Convenient reading, clear and intuitive.
7, have the real time data memory function, can prevent to change battery and power down loss of data suddenly.Under power down mode, inner parameter can permanently keep.
8, straight length requires low (preceding 0～3D, back 0～1D).
9, improve instrument discharge characteristic and measuring condition, made original immeasurable flow become and to measure, solved the problem of " big caliber low discharge " or " the low flow velocity of big caliber ".
10, because not standardization of flowmeter, thereby flowmeter dispatches from the factory and all need carry out reality and fail to be sold at auction calmly, makes metering more accurate, reliable.
11, owing to adopted Victor hot this base curves contraction section and diffuser, saved the instrument harsh conditions strict to forward and backward straight length, made measurement range more extensive, structure is simpler, compact, elegant in appearance.Installation workload and erected cost have been saved.
