Description
Technical field
the utility model relates to flowmeter, is specifically related to a kind of improved vane formula precession spiral flowmeter.
Background technology
Vortex precession flowmeter principle of work: when the fluid axially flowed enters flow sensor entrance, swirl generating body blade forces fluid to be rotated, so produce bumpy flow at swirl generating body center, bumpy flow is precession in Venturi tube, arriving the unexpected throttling of contraction section makes bumpy flow accelerate, after bumpy flow enters diffuser, because the effect of backflow forces it to carry out spiral fashion precession, now the gyro frequency of bumpy flow and the flow velocity of fluid are directly proportional, piezoelectric transducer detects that ultra-weak electronic signal just can obtain the flow signal of our needs by process such as prime amplifiers.
Existing vortex precession flowmeter is the data on flows of two horizontal symmetrical probe measurement medium, what despinner adopted simultaneously is quaterfoil formula, the anti-external interference ability of such design, effective flow signal can not be extracted accurately, especially when medium in upper limit value and lower limit value work time, performance is the most obvious, and quaterfoil formula despinner is when flow increases and heavy caliber works, disorderly medium can than being easier to by despinner, and medium can continue disorderly flowing.So say it, when work under bad environment and pulsation when existing, the vortex precession flowmeter of dual probe, despinner quaterfoil formula can not measuring flow data accurately.
Summary of the invention
The purpose of this utility model is: provide a kind of improved vane formula precession spiral flowmeter, this flowmeter better can extract useful signal, makes the medium flowing through flow probe disorder more stable.
Technical solution of the present utility model is: this flowmeter comprises eddy generator 1, housing 2, pressure transducer 3, calculating instrument 4, temperature sensor 5, flow sensor 6 and despinner 7, eddy generator 1 is installed in one end of housing 2, the other end of housing 2 installs despinner 7, setting pressure sensor 3, temperature sensor 5 and flow sensor 6 in Venturi tube in housing 2 between eddy generator 1 and despinner 7
Pressure transducer 3, temperature sensor 5 are connected calculating instrument 4 altogether with flow sensor 6; It is characterized in that: on housing 2, install undesired signal sensor 8 by blind hole, undesired signal sensor 8 is between pressure transducer 3 and temperature sensor 5.
Wherein, despinner 7 is five vane types.
The utility model has the advantages that: 1, increase the probe that is measured tube wall undesired signal, make vortex precession flowmeter can keep accuracy when external interference, even if so also can the flow of measuring media comparatively accurately under rugged environment; 2, despinner is five vane types, the medium by flow probe can be divided into multiply, make it better to settle out, and reduces gas pulses to the impact of measurement accuracy.
