Abstract: An IC unit includes a scale increment reading module that is configured to: detect, when an indicator in an instrument rotates, rotation of the indicator, and convert the rotation into rotation data; and an antenna that is configured to transmit the rotation data wirelessly from the IC tag unit to a reader. The instrument includes a scale plate, scale increments on the scale plate remain viewable when the IC tag unit is affixed to the instrument. The instrument includes a transparent cover plate, the IC tag unit is affixed to the transparent cover plate when the IC tag unit is affixed to an instrument. The IC tag unit is calibrated by rotating the IC tag unit until an indicating portion of the indicator overlaps a first pointer on the scale plate.

Abstract: Provided are a flow rate measurement device and a flow rate measurement method capable of accurately measuring flow rates not only in a turbulent flow region but also in a laminar flow region and a transition region. A processor includes: a parameter generator that obtains a reference differential pressure in a flow rate calculation formula of expression 1 as follows, based on already-known flow rates and measured differential pressures corresponding thereto, and generates two parameter sets each including coefficients c1 to c3 of the flow rate calculation formula, with the reference differential pressure being a boundary; a differential pressure determination unit that selects one of the two parameter sets by comparing a measured differential pressure of a fluid as a measurement target with the reference differential pressure; and a flow rate calculator that calculates a flow rate of the fluid from the parameter set and the measured differential pressure.

Abstract: To provide an IC tag unit, for an instrument, that can be retrofitted to an analog instrument, that does not impair the calibration state of the instrument, and that can read the value indicated by an indicator and take out the value to outside in a contactless manner. The IC tag unit includes a scale increment reading module 20 which reads operation of an indicator 55. An IC tag 11 performs wireless communication with a wireless reader 70 via an antenna 13? and includes a power module which extracts and supplies drive power for the IC tag by electromagnetic wave of the wireless communication. A sheet which holds the IC tag and an attachment layer which attaches the sheet to the transparent cover plate are provided. The IC tag is provided on the sheet at a position where the IC tag is not overlapped, in a viewing direction, with any of scale increments 56a and an indicating portion of the indicator at a time of mounting the IC tag to a transparent cover plate 53.

Abstract: An IC tag unit, for an instrument, which allows an IC tag into and from which instrument information, calibration information, inspection information, and the like can be written and read to be mounted to an instrument without affecting the IC tag by a metal portion of an instrument body, hindering visibility of a scale of the instrument, and further causing degradation due to dust, raindrops, or the like, and an instrument with the IC tag, are provided. An IC tag 11 having an IC chip 12 and an antenna 13, and mounting means configured to mount the IC tag to an instrument, are provided, and the instrument has scale increments and a pointer, and a transparent cover plate 53 that covers the scale increments 56a and the pointer.
