IMPROVED MEASUREMENT PORT COUPLER AND PROBE INTERFACE

摘要

A measurement port coupler (26) having an improved measurement port (70) to allow fluid from the exterior of the measurement port coupler to be sampled by a probe (124) located on the interior of the measurement port coupler. A valve (72) in the measurement port is recessed in a conical depression (76) set in a wall of the measurement port coupler. The conical depression protects the valve from inadvertent opening and from wear. An improved probe interface (148) is provided to mate with the measurement port. The probe interface includes a face seal gasket (150) that contacts the conical depression of the measurement port prior to the measurement port being opened. A removable cover plate (88) is provided on the exterior of the measurement port coupler to filter any fluids that pass through the measurement port. A removable helical insert (110) is also provided for insertion into the measurement port coupler to aid in orienting the probe when samples or measurements are to be taken.
