涡流 为了蒸汽 适用于天然气

当流体在凹槽主体周围时，产生操作涡流的原则，如图中所示（单击上面的图像选项卡）。漩涡在主体的每一侧交替均匀，彼此相位的180度，导致振荡压力梯度。随着流程增加，涡流的频率与增加的流量成比例地增加，从而产生线性关系。由304或316型不锈钢构造的一般描述可以插入承载气体，液体或蒸汽的管道导管中。插入应用有助于4到12英尺的内径。通过将直接移植到管道中，不需要延长导管线。可选隔离阀允许安装，维修或移除涡旋仪表，而无需关闭气体，液体或蒸汽处理操作。提供键盘或通信接口以访问以下参数：测量单元;可编程流动报警;两个可编程累加器; programmable flow rate pulse output; two programmable optically isolated outputs; battery backed real time clock (RTC); digital communication interface (RS-232 or RS-485); programmable diagnostic events log and register with date/time stamp; programmable process variable log with date/time stamp; calibration and flowing fluid parameters adjustment; extensive diagnostics. Aalborg’s unique dual signal processing technology independently measures each vortex on either side of the bluff body and filters out non-flow noise. This results in less noise and higher accuracy throughout the flow range.
