您用过浮子流量计吗?它结构简单,读数清晰,测量时又没有很大的压力损失,常是您做实验时测流量的最简单的方法。如果用过浮子流量计,您一定也会发现,随着油温或油粘度的变化,这种流量计的示值会出现较大的偏差,给您带来很多麻烦。本来是很有把握的试验,也会因此而无法得到精确的定量结果。 Have you ever used a float meter? It has a simple structure, a clear reading, and no significant pressure loss during measurement. It is often the easiest way to measure the flow when you experiment. If you have used a float meter, you must have noticed that with the change in oil temperature or oil viscosity, there is a large deviation in the indication of the flowmeter, which is troublesome for you. Had been a very confident experiment, will not be able to get accurate quantitative results.
