Abstract：To analyze the advantages and disadvantages of three methods of constant liquid level of the standard metal tank, and determine a new method of constant liquid level of the standard device of first-class metal tank. Based on this method, a standard device of constant level of first-class metal tank is designed, it can automatically and accurately read the liquid level, the automatic control of the value transmission process of the standard device of first-class metal tank was realized. The device can effectively control the temperature of the verification medium and the ambient temperature, and the human impact during the measurement process was reduced. The test shows that: the maximum difference of the reproducibility measurement of constant liquid level scale of the first-class metal tank was 0.04mm, the test standard deviation of the standard device was two thirds lower than that of the traditional standard device.
