工作原理

V. Working Principle

当被测流体流经传感器时，由于叶轮的叶片与流向有一定的角度，流体的冲力使叶片具有转动力矩，克服摩擦力矩和流体阻力之后叶片旋转，在力矩平衡后转速稳定，在一定的条件下，转速与流速成正比，由于叶片有导磁性，它处于信号检测器(由永久磁钢和线圈组成)的磁场中，旋转的叶片切割磁力线，周期性的改变着线圈的磁通量，从而使线圈两端感应出电脉冲信号，此信号经过放大器的放大整形，形成有一定幅度的连续的矩形脉冲波，可远传至显示仪表，显示出流体的瞬时流量或累积流量。

When the measured fluid flows through the sensor, since the blade of the impeller has a certain angle with the flow direction, the impulse of the fluid makes the blade have a rotating torque, and the blade rotates after overcoming the friction torque and fluid resistance. After the torque is balanced, the speed is stable. Under certain conditions, the speed is proportional to the flow velocity. Due to the magnetic conductivity of the blade, it is in the magnetic field of the signal detector (consisting of permanent magnetic steel and coils). The rotating blade cuts the magnetic line of force, periodically changing the magnetic flux of the coil, so that electrical pulse signals are induced at both ends of the coil. This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument remotely to display the instantaneous flow or cumulative flow of the fluid.

在一定的流量范围内，脉冲频率f与流经传感器的流体的瞬时流量Q成正比，流量方程为：

Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor, and the flow equation is:

工作原理

每台传感器的仪表系数由制造厂填写在检定证书中，k值设入配套的显示仪表中，便可显示出瞬时流量和累积总量。

The instrument coefficient of each sensor is filled in the verification certificate by the manufacturer, and the k value is set in the supporting display instrument to display the instantaneous flow and cumulative total amount.
