When the intermittent time of precipitation is more than 15 minutes, it is observed as two times of precipitation before and after the interval. When the intermittent time is less than 15 minutes, it is recorded as one-time precipitation observation. If one-time precipitation crosses 8 hours and 20 hours, it should be measured at 8 hours and 20 hours. Dsj2 type adopts 24 section system for flood season observation.
