Title:
超音波送受信器固定具、超音波送受信器固定具を用いた配管流れ監視装置および配管流れ監視方法
Document Type and Number:
Japanese Patent JP5610300
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To optimize the number and arrangement of ultrasonic transducers in such a manner as to highly accurately monitor a flow rate even for a flow velocity vector in any direction.SOLUTION: An ultrasonic transceiver fixing tool (20) comprises a mounting unit (22) which is capable of fixing a plurality of ultrasonic transceivers (50) at equal intervals on a concentric circle while positioning them outside a pipeline (60) to be measured. Furthermore, a pipeline flow monitoring apparatus (10) comprises, in addition to the ultrasonic transceiver fixing tool (20), a control device (30) which allows the plurality of ultrasonic transceivers (50) fixed in the mounting unit (22) of the ultrasonic transceiver fixing tool (20) to measure a flow velocity variation of a fluid flowing in the pipeline (60) to be measured on the basis of data obtained by measuring information about a flow velocity of the fluid and to acquire flow rate variation from the flow velocity variation.
