涡街流量计球探体育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、理想的测量仪器。主要用于工业管道(Conduit)介质(起决定作用的物质)流体的流量测量,如气体、液体、蒸汽等多种介质。无需导压管和三阀组等,减少泄露、堵塞(dǔ sè)和冻结等。涡街流量计涡街流量计是根据卡门(Karman)涡街原理研究生产的测量气体、蒸汽或液体的体积流量、标况的体积流量或质量流量的体积流量计。主要用于工业管道介质流体的流量测量,如气体、液体、蒸汽等多种介质。
