(一)试验经过:我们应用连通管两端水平高度相等的原理,在胶皮管两端套上玻璃管,把水吸入管内用以校测水尺,并与水准仪对照,试验结果很好(两者相差最大1公分),并曾在北店子、豆腐窝两水位站试验(两个钟头就教会了他们),大家认为这是没有水准仪时校测水尺的好办法,对水位站很解决问题。与水平仪对照十次结果如下表: (A) After the test: We apply the principle of equal height at both ends of the connecting tube, put a glass tube on both ends of the rubber tube, the water is sucked into the tube to measure the water gauge, and the level of control, the test results are good (two A difference of up to 1 cm), and in the North shop, bean curd nest two water level test station (two hours to teach them), we think this is a good way to measure the water level without a gauge, the water station is very good problem. Comparison with the spirit level ten results as follows:
