The utility model discloses a liquid flow on-line automatic metering and calibrating device which comprises a flowmeter to be detected, an input pipeline and an output pipeline, the flowmeter to be detected and a first temperature sensor are installed on the input pipeline, a three-way electromagnetic valve is installed at the output end of the input pipeline and connected with the output pipeline and a detection pipeline, and the output pipeline is connected with the detection pipeline. The detection pipeline is communicated with the metering container, a high-level liquid level sensor, a low-level liquid level sensor and a second temperature sensor are installed in the metering container, and the bottom of the metering container is communicated with the output pipeline through a drainage pipeline. Liquid is stored in the metering container, the volume of the liquid between the low-level liquid level sensor and the high-level liquid level sensor in the metering container is a fixed value, the controller comp
