The advantage and disadvantage analysis of the vortex flowmeter, Xi'an Huaheng instrument for you to bring analysis: the vortex flowmeter is a non-streamlined vortex generator placed in the fluid, the fluid on both sides of the generator alternately releases two series of regularly staggered vortices.

 

 

    渦街流量計(jì)按頻率檢出方式可分為:應(yīng)力式、應(yīng)變式、電容式、熱敏式、振動(dòng)體式、光電式及超聲式等。渦街流量計(jì)是屬于最年輕的一類流量計(jì)，但其發(fā)展迅速,目前已成為通用的一類流量計(jì)。

    Vortex flowmeter can be divided into stress type, strain type, capacitive type, heat sensitive type, vibration type, photoelectric type and ultrasonic type according to frequency detection mode. Vortex flowmeter is the youngest type of flowmeter, but its rapid development has become a general type of flowmeter.

 

 

    優(yōu)點(diǎn):

    (1)結(jié)構(gòu)簡單牢固;

    (2)適用流體種類多;

    (3)精度較高;

    (4)范圍度寬;

    (5)壓損小。

    Advantage:

    (1) The structure is simple and firm;

    (2) There are many kinds of suitable fluids.

    (3) High accuracy;

    (4) Wide range;

    (5) Low pressure loss.

  

    缺點(diǎn):

    (1)不適用于低雷諾數(shù)測量;

    (2)需較長直管段;

    (3)儀表系數(shù)較低(與渦輪流量計(jì)相比);

    (4)儀表在脈動(dòng)流、多相流中尚缺乏應(yīng)用經(jīng)驗(yàn)。

    Disadvantages:

    (1) Not suitable for low Reynolds number measurement;

    (2) Long straight pipe section is needed;

    (3) Instrument coefficient is lower (compared with turbine flowmeter);

    (4) The instrument lacks application experience in pulsating flow and multiphase flow.
