The method includes: adding an oblique line on a water level measuring instrument and marking an abscissa axis, and improving measuring accuracy of a water level gauge in a projection 5 conversion manner, wherein an amplification multiple of improving a reading accuracy by the projection conversion method is related to a ratio of a designed horizontal width of the stripe and a vertical width of the stripe of the water level gauge, the amplification multiple is H/V, H refers to the horizontal width of the stripe of the water level gauge, and V refers to a vertical width of the stripe drop of the water level gauge. In this method, a vertical reading of 0 a measured water level is projected to a horizonal direction by applying a projection mapping principle, and the projection is capable of effectively improving the measuring accuracy of the water level measuring instrument. In addition, different horizontal-vertical ratios are designed according to different measurement requirements to manufacture different water level measuring instruments with different measuring accuracies for actual engineering 5 measurement. Such method of amplifying water level measuring accuracy is simple and effective, low in cost, strong in adaptability, and thus, water level data with higher accuracy is easily obtained.1 /2 ®-HR 2-VR.....
