Abstract
A siphon drainage type rainfall remote measurement device with self-compensation function is provided. The bottom existence of a rain collection barrel () is connected via a flexible tube () to the bottom of a rainfall measuring tube () to which a siphon () is attached. The tube () and a measurement instrument () are installed on a holding frame (). The instrument () is connected to a pressure sensor () and an accumulator () at the bottom of the tube (). The whole device is fixed in an outer barrel (). According to the pressure of the bottom of the tube (), the sensor () measures the height of the water level in the tube () which is directly proportional to the rainfall. The sensor () signal processed by the instrument () is transformed into the rainfall, processed by a compensation algorithm and sent by GSM or GPRS.
