Abstract
A system of measuring properties, such as pressure, and transmitting measurements in a subterranean well. In a described example, a valve system includes a valve having a closure member. A sensor senses a pressure differential across the closure member. A tool positioned in the valve transmits power to the valve to operate the sensor, and the sensed pressure differential is transmitted from the valve to the tool.
