Abstract

This paper reports on experimental measurements of electrode signal noise spectra in an electromagnetic flowmeter designed for flow measurement of the dielectric liquid BP180. The design of the flowmeter tube and the detection electronics is described. Dependence of the noise spectra on flow rate, electrode dimensions and particle content of the liquid is reported. Implications for flowmeter tube design and for the choice of frequency of operation to achieve reasonable signal-to-noise ratios are explained.
