Title:
METHOD AND SYSTEM FOR CALIBRATING FLOWMETER
Document Type and Number:
Japanese Patent JP2004163246
Kind Code:
A
Abstract:
To provide a method and a system for calibrating flowmeters for calibrating a plurality of the flowmeters having difference measuring ranges in a wide range of quantities of flow by one reference flowmeter and calibrating the flow meters at inexpensive costs.
The physical characteristics of a mixed fluids (A+B) of a first fluid (A) having a known quantity of flow and a second fluid (B) passed through the flowmeter to be calibrated (12) are measured. On the basis of the measured value (C), the flowmeter to be calibrated (12) is calibrated.
