HR-LU涡街流量计主要用于工业管道介质流体的流量测量,如气体、液体、蒸气等多种介质。其特点是压力损失小,量程范围大,精度高,在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响。无可动机械零件,因此可靠性高,维护量小。仪表参数能长期稳定。涡街流量计采用压电应力式传感器,可靠性高,可在-20℃~+250℃的工作温度范围内工作。有模拟标准信号,也有数字脉冲信号输出,容易与计算机等数字系统配套使用,是一种比较先进、理想的流量仪表。

一、HR-LU涡街流量计测量原理:

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; 
Pn,P--分别为标准状态下和工况下的绝对压力,Pa;
Tn,T--分别为标准状态下和工况下的热力学温度,K;
Zn,Z--分别为标准状态下和工况下气体压缩系数。 
亚博足球app 由上式可见,VSF输出的脉冲频率信号不受流体物性和组分变化的影响,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。
