涡街流量计

FV系列

●结构简单而牢固，无可动部件，提供*长期运行                                                    

●安装简单，维护十分方便                                                                                          

●检测传感器不直接接触被测介质，性能稳定，寿命长                                                

●输出是与流量成正比的脉冲信号，无*点漂移，精度高                                             

●测量范围宽，量程比可达1:10～1:30                                                                          

●压力损失较小，运行费用低，*减排                                                                     

●应用范围广，蒸汽、气体、油基液体、水基液体的流量均可测量          

原理，结构                                                                       

在流体中设置非流线型旋涡发生体（阻流体），则从旋涡发生体两侧交替地产生两列有规则的旋涡，这种旋涡称为卡曼涡街，通过测量卡门涡街分离频率便可算出瞬时流量和累计流量

特点                                                                     

"其不受介质温度、压力、粘度及组分的影响，同时不堵、不卡、不易结垢、*、高压，适用于恶劣环境。流量计分一体化显示和远传显示，并可输出脉冲信号或电流信号与微机联网。
