ABSTRACT:
An electrified fluid flows through a main pipe and its bypass line including a conducting pipe insulated from the remaining pipes and the main pipe. While the electrified fluid flows through the insulating pipe the latter acquires all electric charges which is, in turn, measured, as a current, by an ammeter connected between the insulated pipe and ground. A flow meter is disposed in the bypass line on the outgoing side of the insulated pipe and measures a flow rate. An electric charge density is calculated from the measured current and flow rate.
