涡街流量计
FV系列
●结构简单而牢固,无可动部件,提供可靠长期运行                                                    
●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,无零点漂移,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,节能减排                                                                     
●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、耐高温、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。
