Abstract

A thermowell assembly is provided for use in measuring a temperature of a process fluid. The thermowell assembly includes an elongate thermowell body which is configured to mount to a process vessel and extend into the process fluid contained in the process vessel. An elongate bore extends along a length of the elongate thermowell body from a proximal end of the elongate thermowell body proximate a wall of the process vessel to a sealed distal end of the elongate thermowell body positioned in the process fluid. A side bore extends from an exterior of the thermowell assembly to the elongate bore. The side bore is positioned outside of the process vessel. A verification valve includes an inlet coupled to the side bore at the exterior of the thermowell assembly and further includes an outlet. The verification valve allows an operator to verify a presence of process fluid in the elongate bore by opening the verification valve and observing process fluid at the outlet of the verification valve.
