Abstract
PURPOSE:To improve the calculation accuracy of a correction coefficient by operating the correction coefficient of the metering instrument with weighing pulses generated according to the passage quantity of fluid. CONSTITUTION:A 1st counting means 1 counts a reference pulse train signal from a reference weight whose number of pulses of the pulse train signal corresponding to the passage quantity of the fluid is recognized previously by a specific number from a 1st reference pulse. A 1st time measuring means 2 measures the reference pulse train generation time from the 1st reference pulse to the preset specific number with the output of this 1st counting means 1. A 2nd counting means 3 counts the number of pulses based upon the output of the 1st counting means when the same fluid as the fluid supplied to the reference weigher is passed through a weigher which needs to be corrected. A 2nd time measuring means 4 measures the pulse train generation time up to the specific pulse number with the output of the 2nd counting means 3, and an arithmetic means 5 operates the correction coefficient of the weigher to be corrected by using those value.
