本文介绍的流量计只有三个活动部分,用于测量半透明清洁液体的流量,例如,测量汽油到汽车发动机的流量.这种流量计根据电光检测原理检测液流压力造成的氯丁橡胶膜位移的大小,测得的结果由表头或其他显示器读出.没有液流时,两个微微受压的反向螺旋弹簧使流量计腔内的氯丁橡胶膜保持在中平面位置(见图)。氯丁橡胶膜中心的圆孔被上下两个弹簧中心校正垫圈卡住.定位螺丝的锥形头部由向上液流侧伸入圆孔内.
This article describes the flow meter has only three active parts for measuring the flow of translucent cleaning fluid, for example, to measure the flow of gasoline to the car engine.This flowmeter based on the principle of electro-optic detection flow pressure of neoprene film displacement The measured results are read by a meter or other display.Without a flow, two slightly compressed reverse coil springs hold the neoprene diaphragm in the flowmeter cavity mid-plane (see photo) . The holes in the center of the neoprene film are jammed by two upper and lower spring center correction washers, and the tapered head of the set screw projects into the circular hole from the upward flow side.
