Abstract：Abstract: made in China 2025 points out that China will not only become a manufacturing power, but also a manufacturing power. With the continuous development of manufacturing industry, hydraulic oil flow measurement technology is widely used in various manufacturing industries. This paper introduces a new type of small flow rate calibration device for hydraulic oil, which can carry out the calibration of flowmeter in hydraulic oil medium. The system should have the functions of automatic control, data collection and processing, saving, inquiring and output of verification results. The calibration/calibration of quasi-turbine flowmeter, gear flowmeter, float flowmeter and other flowmeters can be carried out, and it can also be used to establish relatively high level flow standards for small flow rate measurement of hydraulic oil, which can be applied to technical tests and related studies on measurement.
