The Effect of Abscission of Insulation Lining of Electromagnetic Flowmeter on Output Signal

Abstract:

In pipe of electromagnetic flowmeter must be installed internal insulation lining to prevent the electromagnetic flowmeter signal is short circuit by metal pipe. However, in the process of using the electromagnetic flow meter, insulation lining is easy to fall off because of the fluid temperature and pressure changes, thus lead to the output signal of the electromagnetic flowmeter is changed. The effect of electromagnetic flowmeter insulation lining fall off to the output signal is analyzed by the theory of electromagnetic flow meters weight function. Get the relationship of the output signal and the insulation lining drop area and position. The paper provides a theoretical analysis method for the effect abscission of insulation lining of electromagnetic flow meter on output signal.
