進口旋進旋渦流量計(文丘里)產(chǎn)品用途 Product use

1.在入口側(cè)安放一組螺旋型導流葉片，當流體進入流量傳感器時，導流葉片迫使流體產(chǎn)生劇烈的旋渦流。當流體進入擴散段時，旋渦流受到回流的作用，開始作二次旋轉(zhuǎn)，形成陀螺式的渦流進動現(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 secondary rotation, forming a gyroscopic vortex precession phenomenon

2.進動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，檢測元件測得流體二次旋轉(zhuǎn)進動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 proportional to the flow rate, and is not affected by the physical properties and density of the fluid. The detection element can measure the secondary rotational precession frequency of the fluid to obtain good linearity over a wide flow rate range

3.信號經(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，然后再與溫度、壓力等檢測信號一起被送往微處理器進行積算處理，最后在液晶顯示屏上顯示出測量結(jié)果（瞬時流量、累積流量及溫度、壓力數(shù)據(jù)）The signal is amplified, filtered, and transformed into a pulse signal proportional to the flow rate by a preamplifier, and then sent together with temperature, pressure, and other detection signals to the microprocessor for integration processing. Finally, the measurement results (instantaneous flow, cumulative flow, and temperature, pressure data) are displayed on the LCD screen
