Abstract

PURPOSE: To make it possible to measure a flow rate accurately without any influence of sediment in a measuring pipe, by arranging electrodes, detecting a voltage induced by excited coils, at right angles to the measuring pipe.
CONSTITUTION: Through exciting electric power source 2 that dividing the frequency of AC electric power source 1 by an even number, exciting currents are supplied to excited coils 16a and 16d and a voltage induced byd a flow in a fluid is detected by electrodes 17a and 17b fitted at right angles to measuring tube 11. Consequently, even if sediment 18 is accumulated in measuring pipe 11, a change in sectional area πD2/4 of the pipe and that in measured flow rate f(E) in equation Q=(πD2/4). f(E).t [where Q is a flow rate, D the internal diameter, f(E) the measured flow late, and (t) unit time] cancel, so that the accurate flow rate can be measured without any influence of the sediment.
