  • Calibration method for liquid flowmeter
    Patent number: 11768099
    Abstract: A calibration method for a liquid flowmeter comprising: providing a first tank (12) for receiving said liquid to be measured and a liquid storage tank (14) connected to said first tank (12); providing a liquid delivering line (9) for conveying the liquid from said liquid storage tank (14) to an external device; providing a weighing sensor (22) for weighing the liquid contained in either the first tank (12) or the liquid storage tank (14), wherein during performing the calibration for the flowmeter (20): disconnecting the liquid delivering line (9) in a conveyance direction downstream of the liquid flowmeter (20) from the external device; connecting said liquid delivering line (9) in the conveyance direction downstream of said liquid flowmeter (20) to a calibrating line (7) connected to said first tank (12); and determining a flow rate of the conveyed liquid within a predetermined time interval based on the change in the liquid weight measured by said weighing sensor (22) in said predetermined time interval, w
