Magnetic interface contaminant collector for leak detector in above ground tank

摘要

A magnetic contaminant collector for collecting magnetizable particles is provided for use in an above ground storage tank and is situated in the tank at the interface between the liquid product in the tank and the water in the tank. A leak detector including a sensor assembly comprising an array of conductivity sensors for sensing conductivity is also situated in the tank. The magnetic contaminant collector is located so as to prevent magnetizable particles from fouling the conductivity sensors of the leak detector.
