渦街流量計的優(yōu)缺點(diǎn)分析,西安華恒儀表為您帶來(lái)分析:渦街流量計是在流體中安放一根非流線(xiàn)型游渦發(fā)生體,流體在發(fā)生體兩側交替地分離釋放出兩串規則地交錯排列的游渦的儀表。
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.
渦街流量計按頻率檢出方式可分為:應力式、應變式、電容式、熱敏式、振動(dòng)體式、光電式及超聲式等。渦街流量計是屬于最年輕的一類(lèi)流量計,但其發(fā)展迅速,目前已成為通用的一類(lèi)流量計。
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)結構簡(jiǎn)單牢固;
(2)適用流體種類(lèi)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)不適用于低雷諾數測量;
(2)需較長(cháng)直管段;
(3)儀表系數較低(與渦輪流量計相比);
(4)儀表在脈動(dòng)流、多相流中尚缺乏應用經(jīng)驗。
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.
