Description
Technical field
The utility model relates to flowmeter, is specifically related to the high precision swirl flowmeter.
Background technology
At present, adopt traditional vortex shedding flow meter to measure fluid flow, there is following problem in the tradition vortex shedding flow meter: one, when mounted, need longer straight length on the one hand, the flow velocity of pipeline inner fluid requires than higher on the other hand, make to measure to be subjected to bigger restriction, greatly reduce the use zone of vortex shedding flow meter with use; Two, traditional vortex shedding flow meter needs temperature and pressure compensation in addition, and signal acquisition point is many, and complexity is installed, and the wiring debug difficulties is subject to disturb, and reliability reduces, and measuring accuracy is poor.
Summary of the invention
The purpose of this utility model is: a kind of high precision swirl flowmeter is provided, and this flowmeter structure is simple, will effectively reduce mounting points and straight tube requirement, the accuracy of measurement height.
Technical solution of the present utility model is: this flowmeter comprises standard vortex generation body, the vortex probe, the venturi type housing, connecting pipe, valve, fast-connecting type pressure transducer and signal Processing display, installation code vortex generation body in the venturi type housing, the vortex probe is installed at the rear that is positioned at standard vortex generation body in the venturi type housing, be positioned on the venturi type housing at rear of vortex probe communication type connecting pipe is installed, through valve the fast-connecting type pressure transducer is installed on the connecting pipe, the vortex probe is connected the signal Processing display altogether with the fast-connecting type pressure transducer, and the signal Processing display is installed on the outer wall of venturi type housing through connecting link.
Wherein, integrated encapsulation temperature sensor in the vortex probe, temperature sensor connects the signal Processing display.
Wherein, on connecting pipe, establish PIPE SYPHON.
During use, the venturi type housing of flowmeter is installed on the pipeline; The pipeline inner fluid at first produces the toll bar vortex by standard vortex generation body, and the vortex probe is frequency signal output with the vortex conversion of signals; Secondly pressure signal arrives pressure transducer by connecting pipe and valve, and pressure transducer is converted to electric signal output with pressure signal; After signal Processing display processes and displays result.
The utlity model has following advantage: 1, the housing of this flowmeter is the venturi housing, a bit of straight tube in the housing improves the stability of fluid process greatly, improved fluid velocity, increase fluid produces vortex through vortex generation body intensity, expanded measurement lower limit, adaptation is measured low flow rates of fluid, has enlarged the usable range of swirl flowmeter; 2, integrated encapsulation temperature sensor in the vortex probe, avoiding temperature sensor to stretch into pipeline center influences fluid state, disturbs vortex probe working condition, strengthens compensate function, improves measuring accuracy; 3, pressure transducer is installed on the guide pipe of band PIPE SYPHON, reduces the chance that fluid directly impacts pressure transducer, convenient maintenance; 4, simple in structure, wiring is debugged conveniently easily, gather in real time, and the synchronism height, it is low to detect error.
