Abstract

The invention relates to a flowmeter verification system which comprises a fluid medium storage tank, a measuring container, a fluid pushing device, a verified flowmeter and an upper computer, the fluid medium storage tank is used for storing a fluid medium, the measuring container is used for receiving the fluid medium, and the fluid pushing device is used for feeding the fluid medium into the measuring container and the verified flowmeter. The flow meter is used for measuring the flow of gas extruded by the measuring container after receiving a fluid medium, and the upper computer is used for obtaining the weight of the measuring container before receiving the fluid medium, obtaining the weight of the measuring container after receiving the fluid medium and obtaining the flow volume of the gas measured by the detected flow meter. And the measurement precision of the detected flowmeter is detected according to the obtained values. The invention further provides a flowmeter verification method. Through cooperation of the fluid medium storage tank, the measuring container, the fluid pushing device, the detected flowmeter and the upper computer, automatic metrological verification of different flowmeters can be achieved, and operation convenience and testing precision are improved.
