Abstract
A solenoid operated unit for detecting and bleeding undesired liquid present in desired liquid of different resistivity and specific gravity, the two liquids being immiscible with each other; with an electrical arrangement having a pair of parallel sensor pins and a pair of serial sensor pins. A dual function diaphragm ensures suitability for use with contaminated fluids. A pressure equalization outlet ensures smooth and speedy bleeding of undesired liquid. A modular mechanical sensor, when provided, provides redundancy such that desired fluid is not drained in situations of any electro-mechanical failure.
