Turbine flow meter concept
2011-9-30 9:44:13

速度式流量计中涡轮流量计是应用最广的流量仪表。 Turbine flow meters are the most widely used flow meters in speed flow meters. 一多叶片转子( 也可以说 涡轮) 在流体动能 作用下 旋转的角速度与管内平均流速成正比这一特性 ,制作而 成的流量计。 It is a flow meter manufactured by using a multi-blade rotor ( also called a turbine ) in the pipeline under the action of fluid kinetic energy , the angular velocity of rotation is proportional to the average flow velocity in the pipeline .

机械、磁感应、光学方式、电子方式等手段检测得到涡轮的转速, 目前一般是通过磁感应方式来测量涡轮转速的。 The rotational speed of the turbine can be detected through mechanical, magnetic induction, optical, electronic and other means . At present , the rotational speed of the turbine is generally measured by magnetic induction. 由传感器和显示仪表两部分组成,也可 做成一体式涡轮流量计 Structurally, a turbine flowmeter is generally composed of two parts, a sensor and a display instrument, and can also be made into an integrated turbine flowmeter . 测量精度很高,可 与容积式流量计 并列,可以说是目前流量计中测量精度较高的流量计。 Its measurement accuracy is very high, and it can be juxtaposed with the volumetric flowmeter . It can be said that it is a flowmeter with higher measurement accuracy in current flowmeters.
