A Japanese Industrial Standard "Pneumatic fluid power - Components using compressible fluid - Determination of flow rate characteristics " on test method of flow characteristic of pneumatic equipment will be enforced near. In this Japanese Industrial Standard, a demand on allowable error of measuring instrument of flow rate, pressure and temperature is very severe. Especially on the flow rate, it is very difficult to satisfy the accuracy of the regulation by the flowmeter of the marketing. Therefore, it is necessary to calibrate purchased flowmeter, when the flow characteristic of pneumatic equipment is tested. In the region where the downstream pressure is smaller than critical pressure, the air flow rate through the restriction does not change, when the upstream pressure of the restriction is fixed. In this study, the flowmeter of the marketing was calibrated using this property. As the result, the measurement accuracy of the calibrated flowmeter of the marketing satisfied the accuracy regulated in a Japanese Industrial Standard.
