现在介绍几种巧用袖珍电子计算器的应用实例和一种没有“累加”功能计算器改装为光电计数器的方法。一、流量计利用袖珍电子计算器改装的流量计,可以测量管路流体(如水、燃油、润滑油等液体)的流量,与其他测量流量的方法相比,具有精度高、操作简单、工作可靠等优点。流量计的工作原理如图1所示。当管 Here are a few examples of how to use a pocket calculator and how to convert a calculator to a photoelectric counter without a “Accumulate” function calculator. First, the flowmeter Pocket electronic calculator modified flowmeter, you can measure the pipeline fluid (such as water, fuel, lubricants and other liquids) flow, compared with other methods of measuring flow, with high precision, simple operation, reliable work Etc. Flowmeter works as shown in Figure 1. When the tube
