Summary:PCT No. PCT/FI96/00029 Sec. 371 Date Sep. 4, 1997 Sec. 102(e) Date Sep. 4, 1997 PCT Filed Jan. 15, 1996 PCT Pub. No. WO97/26442 PCT Pub. Date Jul. 24, 1997A measuring procedure and a flowmeter for the measurement of liquid flow in a hole bored in the ground, such as rock. The flowmeter consists of a long cylindrical body comprising: ring-shaped sealing elements (5) placed at a distance from each other in the longitudinal direction to seal off a certain volumetric section from the rest of the hole; dividing elements (6) for dividing the volumetric section into at least three sectors (1) extending from one sealing element to the other; flow ducts (2) interconnecting the sectors; an impulse source (3) placed at the junction of the flow ducts; and sensors (4) placed in the flow ducts for measuring the magnitudes and velocities of currents between sectors by monitoring the velocity and direction of motion of an impulse.
