Abstract
A downhole sub for instrumentation, such as a fiber optic sensor. The sub is configured to be connected to a string of pipe, such as a string of tubing. The sub first comprises an essentially concentric tubular body. The tubular body has an inner diameter that generally conforms to the inner diameter of the tubing string. A recess is formed within the wall of the tubular body. Next, the sub comprises a gauge housing that is received within the recess of the tubular body. The gauge housing includes a plate portion that is exposed to fluids within the production tubing. The gauge housing further includes a side bore that receives a sensor. One or more gauge housing ports are pre-fabricated into the gauge housing to provide fluid communication between the inner bore of the production tubing and the side bore of the gauge housing. The entire sub is preferably self-contained without any elastomers or metal-to-metal seals.
