WJ-LU智能涡街流量计的详细资料: |
|
智能涡街流量计原理 在流体中设置三角柱型旋涡发生体,则从旋涡发生体两侧交替地产生有规则的旋涡,这种旋涡称为卡门旋涡,如右图所示,旋涡列在旋涡发生体下游非对称地排列。 f=SrU1/d=SrU/md (1)
管道内体积流量qv为
K=f/qv=[πD2md/4Sr]-1 (3) (4)
式中 qVn,qV--分别为标准状态下(0oC或20oC,101.325kPa)和工况下的体积流量,m3/h;
涡街流量计便是依据卡门旋涡原理进行封闭管道流体流量测量的新型流量计。因其具有良好的介质适应能力,无需温度压力补偿即可直接测量蒸汽、空气、气体、水、液体的工况体积流量,配备温度、压力传感器可测量标况体积流量和质量流量,是节流式流量计的理想替代产品。 为了使用方便,电池供电的本地显示型涡街流量计采用微功耗高新技术,采用锂电池供电可不间断运行一年以上,节省了电缆和显示仪表的采购安装费用,可就地显示瞬时流量、累积流量等。温度补偿一体型涡街流量计还带有温度传感器,可以直接测量出饱和蒸汽的温度并计算出压力,从而显示饱和蒸汽的质量流量。温压补偿一体型带有温度、压力传感器,用于气体流量测量可直接测量出气体介质的温度和压力,从而显示气体的标况体积流量。 ◆测量介质:气体、液体、蒸气 涡街流量计的优点:
涡街流量计的技术参数
●测量范围
●额定压力:1.6MPa、2.5MPa、6.3MPa
●工作电源
●输出信号:脉冲输出、4~20mA 电流输出,RS485通讯等三种输出可供选择 一般原则:在易受电噪声干扰的场所,使用屏蔽电缆。屏蔽层应可靠的接在放大器的接地螺丝上或在控制室接工作接地。在高温或低温环境中或者是现场空气中含有油、溶剂或其他腐蚀性气体时,要采用适合于这种特殊场合的的屏蔽电缆。 |
