    • PROBLEM TO BE SOLVED: To provide a calibration method and system for calibrating a meter devoid of a process connection part.
      SOLUTION: The system 200 includes a connection adapter 216, where the system is operable for calibrating both linear and nonlinear meters with multiple flow rates, and is suitable for use with different standard references including both gravimetric and master standard references. The process connection adapter includes: a system mating part in the form of a flange, sanitary or some other type of sealing connection for piping for ensuring a leak-free seal between the process connection adapter and a calibration system; a meter mating part for ensuring a leak-free seal between the process connection adapter and a part of the meter to be attached to the process connection part; and an intermediate part for fluidly connecting the system mating part to the meter mating part.

    • PURPOSE:To achieve a higher accuracy of the flow rate measurement by using a microcomputer in which the spproximation characteristic of a flow rate sensor is stored for a car fuel. CONSTITUTION:A reference time generator 22 is connected to a microcomputer muCP12 for a fixed cycle of interruption and a signal is fed from a flow rate sensor 24 corresponding to the flow rate passed. In addition, one action is selected by the operation of a selection switch 28 and indicated 30. Several kinds of approximation characteristics of the sensor 24 are stored in the microcomputer muCP12. According to a specified procedure, the flow rate characteristics best matching the actual condition are automatically selected to calibrate the measurement of the flow velocity.
