installing a water level sensor (60) on a sensor mounting frame (40), connecting the sensor mounting frame (40), a filter assembly (30) and a lifting rope (50), placing the sensor mounting frame (40) and the filter assembly (30) into a pipe body (10), enabling the filter assembly (30) to shield a water seepage hole (11), and fixing the upper end of the lifting rope (50) on the upper part of the pipe body (10);
placing the pipe body (10) into the measuring hole and fixing firmly, and starting monitoring after the reading of the water level sensor (60) is stable;
after the preset time, whether the reading of the water level sensor (60) generates errors or mistakes is judged, if not, the water level sensor is continuously used, and if the reading generates errors, the sensor mounting frame (40) and the filter assembly (30) are taken out from the measuring pipe body (10) through the lifting rope (50), replaced according to requirements and then placed into the measuring pipe body (10) again, and the filter assembly (30) is enabled to shield the water seepage hole (11).
