品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……、进口旋进旋涡流量计 文丘里流量计 产品用途 Product use
1.在入口侧安放一组螺旋型导流叶片，当流体进入流量传感器时，导流叶片迫使流体产生剧烈的旋涡流。当流体进入扩散段时，旋涡流受到回流的作用，开始作二次旋转，形成陀螺式的涡流进动现象 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.进动频率与流量大小成正比，不受流体物理性质和密度的影响，检测元件测得流体二次旋转进动频率就能在较宽的流量范围内获得良好的线性度 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.信号经前置放大器放大、滤波、整形转换为与流速成正比的脉冲信号，然后再与温度、压力等检测信号一起被送往微处理器进行积算处理，最后在液晶显示屏上显示出测量结果（瞬时流量、累积流量及温度、压力数据）The signal is amplified, filtered, and transformed into a pulse signal proportional to the flow rate by a preamplifier, and then sent together with jpgtemperature, 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
