Zusammenfassung: | The utility model provides a transmissive and reflective hydrolgical gage with two colors composed of a chamber, a prism and a sight window. The utility model is characterized in that the prism adopts a scalene right-angled triangle prism, and the light source is positioned under the vertical angle of the prism, which can make the observer accurately judge the height of the water level, the state of no water or full of water not only within a +/-10 DEG range but also in a distant range. In addition, when used, the utility model doesn't need any adjustment. |
