Background
At present, the pipeline type liquid flowmeter with a larger caliber cannot be periodically checked off line due to the continuity of data acquisition, difficulty in disassembly, liquid medium and the like, so that the liquid flowmeter is a common calibration method in calibration.
The standard specifications released in the calibration of the liquid flowmeter in China are as follows: CJ/T364-2011 'online calibration requirement of pipeline type electromagnetic flow meters', JJF (Yu) 276-2019 'online sewage detection flow meter', JJF (Anhui) 73-2019 'online calibration specification of electromagnetic flow meters', JJF (Su) 228-2019 'online calibration specification of electromagnetic flow meters', JJF (wing) 182-2020 'online calibration specification of large-caliber electromagnetic flow meters' and the like.

The standard meter method is mainly characterized in that a standard flowmeter is installed at the upstream or the downstream of a flowmeter to be measured in a serial mode, and the accumulated flow of the standard flowmeter is compared with the accumulated flow of the meter to be measured.
