Title:
CALIBRATION SYSTEM OF ELECTROMAGNETIC CURRENT METER, COMPUTATION SYSTEM OF CALIBRATION COEFFICIENT, AND METHOD THEREOF
Document Type and Number:
Japanese Patent JP2014153093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a calibration system of an electromagnetic current meter, which is capable of suitably calibrating a measurement current velocity measured by the electromagnetic current meter regardless of the change in arrangement pattern of a structure in accordance with the changed arrangement pattern of the structure.SOLUTION: A calibration system 50 of an electromagnetic current meter 1 includes: the electromagnetic current meter 1 which is provided adjacently to a structure taking a prescribed arrangement pattern and measures a current velocity of a fluid flowing in a narrow part around the adjacent structure, as a measurement current velocity; and a control device 11 which acquires a calibration coefficient associated with the arrangement pattern of the structure adjacent to the electromagnetic current meter 1, out of a plurality of calibration coefficients associated with a plurality of arrangement patterns of the structure and calibrates the measurement current velocity measured by the electromagnetic current meter 1, on the basis of the acquired calibration coefficient and computes the calibrated measurement current velocity as a calibrated current velocity.
