Investigation of the Effect of Electrodes Distance on the Polarization Impedance Type Flowmeter

The electrode polarization impedance type flow transducer is a simple, obstruction less, and cost-effective flow meter for measuring the flow rate of the conductive liquid. In this flow meter, four electrodes placed diametrically opposite to each other with a separation of certain distance forms a bridge. The flow transducer output nonlinearly varies with flow rate, excitation frequency, current density, and separation distance between the electrodes. In this paper, we have observed and analyzed the effect of output of electrode polarization type flow meter with the variation in separation distance between the electrodes. In this paper, after theoretical analysis, the experiment has been performed, and its results and graphs are reported. It has been observed that the experimental results follow the theoretically derived equations.
