水工模型试验测非恒定流水面高程时(倒如调压井水面),可采用浪高仪配示波器观测。测恒定流水面一般采用水位测针,测针精度可达0.1mm,使用也很简便。但对虽系恒定流而水面波动较大的情况下,水位测针就显得不适应了。为此,我们试作了几种用小电池供电的小型简易电子仪器,可直接套在水位测针头上,直接观测波动水面,并获得多种用途,而仍保持其使用简便的优点。计有平均水位计、高水位记数计、最高水位测针。经我所试验部门使用证实,仪器虽极简易但相当实用,几年来常有外省水科
Hydraulic model test unsteady flow surface elevation (down, such as surge shaft water), can be used to observe the wave height meter oscilloscope. Constant water surface to be measured using water level probe, stylus accuracy of up to 0.1mm, the use is also very simple. However, although the Department of constant flow and the water surface fluctuations in the case of large, the water level does not seem to fit the needle. To this end, we have tried several small, simple-to-use electronic devices powered by small batteries, which can be set directly on the water level stylus to directly observe the fluctuating water surface for a variety of uses while still maintaining its ease of use. Have an average water meter, high water mark count, the highest water level stylus. The use of the test by our department confirmed that although the instrument is extremely simple but quite practical, several provinces often have water
