Vortex:

Practically it is a volumeteric flow measuring device and it is not possible to calibrate online in field in most of the cases (Provide you have a proper bypass arrangement and proovers in place) , hence it is to be sent to calibration LAB where it will be compared with MASTER meter.

This MASTER meter must have superior accuracy than UUC (Unit Under Calibration).
Usually the large volume flow is tough to establish at calibration LAB hence Gravymeteric method is used in which water is passed through UUC and compared with high accuracy Load-cell. Since water density is known and constant, volume flow is calculated and new K-factor of meter is calculated.

Mass-flowmeter / Coriolis meter : Same Above mentioned Gravymeteric method is used.

Hope this will help ..!!!
