摘要： PROBLEM TO BE SOLVED: To provide a flow velocity measuring system capable of performing high-reliability flow velocity measurement, even if sensors and a channel deteriorate with a passage of time.
SOLUTION: This system is provided with a flow velocity sensor 101 and a water level sensor 102 installed in the channel, a storage means 111 for storing a plurality of flow velocity versus water level correlation curves determined beforehand changing the installation position of the flow velocity sensor and conditions of the channel into a plurality, a correlation curve selection means 112 for selecting one out of the flow velocity versus water level correlation curves from the storage means 111 on the basis of the installation position of the velocity sensor 101 and the channel conditions, and a correction means 113 for calculating a correction amount for a measured flow velocity value input from the velocity sensor 101 on the basis of the flow velocity versus water level correlation curve selected by the selection means 112 and a measured water level value input from the level sensor 102 and correcting the measured flow velocity value with this correction amount.

摘要： PROBLEM TO BE SOLVED: To provide a flow velocity measuring device for performing reliable measurement of flow velocity for a long term.
SOLUTION: This flow velocity measuring device 10 includes a housing 16 forming an airtight chamber 15, an FBG 17 stored in the housing 16, and a load transfer mechanism 18 for making stress act on the FBG 17. The load transfer mechanism 18 has an upstream pressure plate 19, and one shaft 20 whose one end section 20a is fixed to the upstream pressure plate 19 side, and applies the stress to the FBG 17 by its displacement to displace the FBG 17. The load transfer mechanism 18 includes a diaphragm boss 21 that passes the shaft 20 and is fixed to the upstream pressure plate 19, and a diaphragm 22 whose inner periphery is fixed to the outer periphery of the diaphragm boss 21 and outer periphery is fixed to the housing 16 side. An O ring is disposed between the upstream pressure plate 19 and the shaft 20 and between the diaphragm boss 21 and the shaft 20.
