進(jìn)口旋進(jìn)旋渦流量計(jì) 文丘里流量計(jì) 產(chǎn)品用途 Product use
1.在入口側(cè)安放一組螺旋型導(dǎo)流葉片,當(dāng)流體進(jìn)入流量傳感器時(shí),導(dǎo)流葉片迫使流體產(chǎn)生劇烈的旋渦流。當(dāng)流體進(jìn)入擴(kuò)散段時(shí),旋渦流受到回流的作用,開(kāi)始作二次旋轉(zhuǎn),形成陀螺式的渦流進(jìn)動(dòng)現(xiàn)象 A set
of spiral guide vanes is placed on the inlet side. When the fluid enters the
flow sensor, the guide vanes force the fluid to generate a violent vortex flow.
When the fluid enters the diffusion section, the vortex flow is subjected to
the effect of reflux and begins to undergo seco
2.進(jìn)動(dòng)頻率與流量大小成正比,不受流體物理性質(zhì)和密度的影響,檢測(cè)元件測(cè)得流體二次旋轉(zhuǎn)進(jìn)動(dòng)頻率就能在較寬的流量范圍內(nèi)獲得良好的線性度 RETZ
The precession frequency is proportio
3.信號(hào)經(jīng)前置放大器放大、濾波、整形轉(zhuǎn)換為與流速成正比的脈沖信號(hào),然后再與溫度、壓力等檢測(cè)信號(hào)一起被送往微處理器進(jìn)行積算處理,最后在液晶顯示屏上顯示出測(cè)量結(jié)果(瞬時(shí)流量、累積流量及溫度、壓力數(shù)據(jù))The
signal is amplified, filtered, and transformed into a pulse signal proportio
