     涡街流量计的优缺点分析,西安华恒仪表为您带来分析:涡街流量计是在流体中安放一根非流线型游涡发生体,流体在发生体两侧交替地分离释放出两串规则地交错排列的游涡的仪表。  

    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.
 
 
    涡街流量计按频率检出方式可分为:应力式、应变式、电容式、热敏式、振动体式、光电式及超声式等。涡街流量计是属于最年轻的一类流量计,但其发展迅速,目前已成为通用的一类流量计。
    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.
 
 
    优点:
    (1)结构简单牢固;
    (2)适用流体种类多;
    (3)精度较高;
    (4)范围度宽;
    (5)压损小。
    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.
  
    缺点:
    (1)不适用于低雷诺数测量;
    (2)需较长直管段;
    (3)仪表系数较低(与涡轮流量计相比);
    (4)仪表在脉动流、多相流中尚缺乏应用经验。
    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.
