三、分类1.按传感器结构分类(1)轴向型(普通型)叶轮轴中心与管道轴心重合,是涡轮流量计的主导产品,有全系列产品(DN10～DN600).(2)切向型 叶轮轴与管道轴心垂直,流体流向叶片冲角约90°,适合于小口径微流量产品.(3)机械型 叶轮转动直接或经磁耦合带动机械计数机构,指示积算总量,测量精度比电信号检测传感器稍低,其传感器与显示仪组成一体,方便使用.(4)井下专用型 运用于石油开采、井下作业及
Third, the classification 1. According to the sensor structure classification (1) axial type (common type) impeller shaft center coincides with the pipe axis, turbine flowmeter is the leading product, a full range of products (DN10 ~ DN600) Vertical impeller shaft and the pipe axis, the flow of fluid to the blade angle of about 90 °, suitable for small diameter microflow products. (3) mechanical impeller rotation directly or through magnetic coupling driven mechanical counting agencies, indicating the total volume, The measurement accuracy is slightly lower than that of the electric signal detection sensor, and the sensor and the display instrument are integrated and convenient to use. (4) The underground type is used in the fields of oil extraction, downhole operation and
