3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 reading pointer readingpointer Fixed pointer for precise indication of the position of the water gauge reading in the well. 3.2 The elevation value at the location of the readout pointer. Note. After the reading pointer is installed, the height obtained by continuous measurement with the calibration level point or basic level point according to the national level measurement requirements of level four or above. 3.3 reference standard reference standard The comparison standard used in the on-site comparison test.

4 principles

The laser range finder is used as the reference standard, the reference standard and the float type tide gauge measure the tide height at the same time, and the tide height measured by the reference standard is used as the standard. Quasi-tide height, the tide height measured by the float type tide gauge is used as the measured value, one set of data is read every 10s, 10 sets of data are read continuously and evenly, and the calculation The arithmetic mean value of the difference of each group of data is taken as the measurement error of the float type tide gauge, that is, the comparison measurement result.
