PROBLEM TO BE SOLVED: To provide an oil feeder capable of making fine adjustment, coping with the volume of an instrument error measure set for each country, and more surely preventing alteration of an instrument error.SOLUTION: An oil feeder 1 includes: a flowmeter 8 for measuring the quantity of oil supplied; and a display device 16 for displaying the quantity of oil supplied on the basis of a measurement value of the flowmeter. The oil feeder includes instrument error adjusting means for electronically making an instrument error adjustment for the flowmeter using a coefficient of instrument error calculated on the basis of the measurement value of the quantity of oil supplied in the flowmeter and a true value of quantity of oil supplied measured on the outside of the oil feeder. The instrument error adjusting means may include: counting means 36 for multiplying the measurement value of quantity of oil supplied in the flowmeter by an instrument error count; and control means for controlling the display device to display the arithmetic result of the counting means. |
