[0002] A meter generally refers to an instrument used to measure the total amount (accumulated amount) of fluid flowing through a pipeline within a certain time interval. A meter is an instrument for measuring the flow of cold water or hot water. It generally refers to an instrument used to measure the total amount (accumulated amount) of fluid flowing through a pipeline within a certain time interval, such as a water meter, a gas meter, etc. Users use small-diameter meters, while factories or water companies, heating plants and other units use large-diameter meters. Before the meter leaves the factory, various indicators of the meter need to be calibrated. Since the meter has to withstand water pressure during use, the pressure bearing capacity of the meter is also one of the calibration indicators. At present, calibration is only performed through manual operations, and the calibration results have poor stability and low accuracy. Therefore, we have introduced a meter-type calibration device.
