PROBLEM TO BE SOLVED: To provide a measurement information gathering system, by which the reliability of transmission of measurement information transmitted from radio devices to an information gathering device via radio repeaters. SOLUTION: A hyetometer 22 in each of observational stations 12 (i) outputs a measured amount of rainfall to the radio device 24 as rainfall information, and the radio device 24 transmits a measured information frame containing the rainfall information input and radio device identification data for identifying its own device to each of two radio intermediary devices 16 (j) via radio transmissions 14, 20. Each radio intermediary device 16 (j) imparts the radio intermediary device identification data, for identifying its own device to the measurement information frame received to transmit the measurement information frame, to which the data have been imparted to the information gathering device 26 via radio transmission 15. The information gathering device 26 gathers each piece of rainfall information, contained in each of the measurement information frames received via the two routes through the two radio intermediary devices 16 (j).
