Description of the calibration method of electromagnetic flowmeter

There are three calibration methods for electromagnetic flowmeters:
1. Standard table method. By comparing the cumulative flow of the calibration and standard tables over a certain period of time, the data of the calibration is obtained, which is the most commonly used calibration method.
2. Container method. By comparing the cumulative flow rate and the volume of the standard container in a certain period of time, the data of the calibration table is obtained, and the precision is relatively high.
3. Weighing method. By comparing the standard flow obtained by the calibration amount and weighing in a certain period of time, the data of the calibration table is obtained, and the precision is also relatively high.
