In a district of Nanjing,thousands of small-caliber electromagnetic flowmeters have been installed in the project of full coverage of rural domestic sewage treatment facilities,most of which are used as sewage metering and require regular verification or calibration.Therefore,a set of mobile multi-epitope small flow standard device is designed in this project and verified by experiment.The experiment shows that the device can carry out the verifi-cation and calibration of 3 sets of 1.0 class and below electromagnetic flowmeters with the same caliber range not exceeding DN(10～25)mm,and the total power does not exceed 1kW.
