Fluid Leak Detection System for Determining the Rate of Fluid Leakage Through a Geomembrane

Abstract: 

A system and a 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 connected with an inverted funnel to confine the flow, and further includes forming a transverse magnetic field thereacross, a sensor mutually perpendicular to the passage and the magnetic field and a voltmeter connected to the sensor for measuring the voltage. The voltage is dependent on the rate of flow of the leaked liquid along the passage.
