<p>A system and method for measuring the leakage flow rate from an impounded liquid through a tear or hole in a geomembrane liner is set forth. It utilizes a narrowed passage (26) connected with an inverted funnel (28) to confine the flow, and further includes induction coils (34, 36) for forming a transverse magnetic field thereacross, a sensor (40) mutually perpendicular to the passage and the magnetic field and a voltmeter (42) connected to the sensor for measuring the voltage. The voltage is dependent on the rate of flow of the leaked liquid along the passage.</p> |
