Abstract
Systems, methods, and apparatus including a downhole membrane potentiometer that may be used in well systems. The downhole membrane potentiometer may include a first circuit film having a resistance trace, a second circuit film having a collector trace, and an insulator spacer coupled between the first circuit film and the second circuit film. The insulator spacer may include one or more pressure vent holes in a first side of the insulator spacer and one or more pressure vent holes in a second side of the insulator spacer to minimize a differential pressure between the inside and outside of the downhole membrane potentiometer.
