HDW系列弯管流量计工作原理 Working principle
HDW系列弯管流量计属于差压式流量测量系统。是利用流体流经弯管传感器时做圆周运动面产生离心力的原理，该离心力的大小与流体速度、流体质量(密度)以及做圆周运动的曲率半径等因素有关。
The HDW series ellow meters are differential pressure type flow measuring systems，which work on tihe principle of a centrifugal force produced while the fluid is passing the elbow sensor in circular motion.The centrifugal force is related to factors such as the fluid velocity，ftuid mass(density)and curvature radius of the circular motion.
