靶式流量计工作过程中示值出现非正常增大造成该现象的主要原因有：b高结圬条件下靶片和靶杆产生严重结圬使受力元件靶板沿测量管轴线上投影面积增加即靶片与测量管之间环形过流面积减少进而在相同流量下传感器受力增大zui终导致流量示值非正常增加;处理方法：取下过渡部件用工具将靶片和靶杆以及测量管内壁上的圬物即可。计量误差大造成该现象的原因很多其zui主要的原因为以下几种：a安装时靶式流量计与连接管道相对同心度出现较大错位密封垫片未同心从而形成节流阻件极大影响被测介质流态;靶式流量计常见故障及处理方法b靶式流量计前后直管段太短并于靶式流量计前直接安装了弯头阀门等极大干扰被测介质流态部件;处理方法：按照说明书要求进行安装或对靶式流量计进行实地实流标定。气体涡街流量计输出的脉冲频率信号不4000118588和组分变化的影响即仪表系数在一定雷诺数范围内仅与旋涡发生体及管道的形状尺寸等有关。但是作为流量计在物料平衡及能源计量中需检测质量流量这时流量计的输出信号应同时监测体积流量和流体密度流体物性和组分对流量计量还是有直接影响的。气体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。
