Measuring flow directions and velocities - comprises sealing off volumetric section, dividing section into three sectors and using sensors placed in flow ducts

摘要

Flow measuring procedure for measuring liquid flow in a hole bored in the ground comprises: (a) certain volumetric section being sealed off from hole in longitudinal direction; (b) volumetric section being divided into at least three sectors (1); (c) sectors being interconnected via flow ducts (2) permitting free flow between sectors; and (d) directions and velocities of currents between sectors being measured by sensors (4) placed in flow ducts.
