    • A flowmeter, particularly for measurement of fuel flow rates to engines having a bore within a body with axially disposed inlet and outlet parts, a rotor in the bore with a hub carrying helical vanes substantially filling the cross-section of the bore and a light source with an associated photo responsive device arranged so that the vanes of the rotor interrupt the light beam to produce an electrical output signal with a frequency component proportional to the speed of rotation of the rotor.
    • 一种流量计,特别是用于测量具有在轴向设置的入口和出口部分内的具有孔的发动机的燃料流速,所述孔中的转子具有承载基本上填充所述孔的横截面的螺旋叶片的轮毂和光源 其中相关联的光响应装置被布置成使得转子的叶片中断光束以产生具有与转子的旋转速度成比例的频率分量的电输出信号。
