[0058] In the above embodiment, the data processing device 31 is implemented by the physical quantity measuring device 3, which is a device separate from the pump device 2. However, some or all of the functions of the data processing device 31 (particularly the functions of the measurement control unit 32) may be implemented by the pump device 2 by being incorporated in the pump control panel 23 of the pump device 2. In that case, the physical quantity sensor 30 and the pump control panel 23 may be connected by wire or wirelessly to transmit and receive various data. The pump device 2 may also be provided with the physical quantity sensor 30.
[0059] In the above embodiment, the case has been described where the processed data transmitted by the physical quantity measuring device 3 is relayed by the data collecting device 4 and received by the data management device 5, and stored in the management storage unit 52 as a storage device. However, the device to which the processed data is transmitted and the storage device to which the processed data is stored may be changed as appropriate. For example, the processed data may be transmitted to the data management device 5 or the terminal device 6, or may be stored in a storage device provided in the data collecting device 4 or the terminal device 6.
[0060] In the above embodiment, the physical quantity measuring device 3, the data collecting device 4, and the data management device 5 operate according to the flowcharts shown in Figures 6 and 7. However, the order of execution of each step may be changed as appropriate, and some steps may be omitted.
[0061] In the above embodiment, the physical quantity measuring device 3 is described as being attached to the pump device 2, but it may be attached to various devices such as a refrigerator, a gas machine, a machine tool, a press device, a conveying device, a diagnostic device, etc. In that case, the physical quantity sensor 30 may measure a physical quantity caused by the various devices.
