Discussion on On-line Calibration Method of Electromagnetic Flowmeter
Electromagnetic flowmeter has the advantages of simple operation,high precision,strong adaptability,and does not affect the flow distribution of the measured fluid.It is widely used in water supply,chemical industry,phar-macy,water treatment,environmental protection,food and beverage and other fields.In the case that it is inconvenient to disassemble or cannot be disassembled due to the requirements of continuous production,online calibration of elec-tromagnetic flowmeter is a feasible method to meet the requirements of its traceability.This paper introduces two on-line calibration methods of electromagnetic flowmeter,and the results show that both methods are feasible for online calibration of electromagnetic flowmeter.When the measurement environment is ideal,the standard meter method is the first choice.When the measurement conditions are not ideal,the electric parameter method can qualitatively eval-uate the measurement performance of electromagnetic flowmeter.
