Abstract

A measurement instrument comprises a housing including a measurement circuit for measuring a process variable. A primary element is adapted to extend into a process vessel. The primary element includes an elongate hollow sleeve open to an interior of the process vessel, in use. A process adapter operatively connects the housing to the primary element for securing the instrument to the process vessel. The process adapter comprises a through opening. A seal adapter is received in the process adapter through opening. The seal adapter comprises a central bore opening into the hollow sleeve. The process adapter comprises a flushing port in communication with the through opening and an annular space between the seal adapter and the process adapter intersecting the flushing port. The seal adapter comprises a plurality of jet passages aligned at the annular space and opening into the bore.
