Abstract: A process fluid pressure measurement system is provided. The system includes a process fluid pressure transmitter having a pair of process fluid ports disposed coplanar with one another on a bottom surface thereof. The process fluid pressure transmitter is configured to measure a differential pressure between the pair of process fluid ports and provide an indication of the measured differential pressure over a process communication loop. A process fluid flange has a first surface configured to mount to the surface of the process fluid pressure transmitter, a second surface opposed to the first surface, and at least one lateral sidewall extending between the first and second surface. A plurality of fins are disposed proximate the lateral surface.

Abstract: A combined temperature and pressure sensing probe assembly for a flow measurement system comprising a body, a portion of which is adapted for insertion into fluid flowing in a confined conduit, such as a pipe. Within the body are separated plenums which are exposed respectively to high and low fluid pressures in the flow. A manifold block is that portion of the body which is disposed outside of the pipe containing the fluid flow. Along with valves and fluid conveying channels, the block is equipped with a duct for carrying electrical conductors and also contains a traversing bore which is aligned with the body and is in communication with the conductor carrying duct. An electrically responsive temperature sensor is disposed within or formed from the body. Conductors from the temperature sensor are directed from the manifold's bore through the connecting duct to a point exterior of the manifold.

Abstract: A fluid pressure and temperature sensing probe assembly for a mass flow measurement system comprising, a tubular body, a portion of which is adapted for insertion into the fluid flowing in a confined conduit, and having, within the body, a pair of separated plenums. Openings are provided in the tubular body which expose the respective plenums to high and low fluid pressures in the fluid flow. An electrically responsive temperature sensor, having an electrical signal output, is disposed within the tubular body of the probe. A pressure transducer, in fluid communication with the plenums, converts the fluid pressures in the plenums to at least one electrical signal representative of the difference between the high and low fluid pressures. A transmitter transmits the electrical signal from the pressure transducer and the electrical temperature signal to a remote location.

Abstract: This invention relates to an improved high pressure mounting for removably positioning pitot tube type flow measurement devices in a pipeline where the mounting includes a hollow tubular collar welded to the pipe in alignment with a probe-receiving opening therein and which is sized to slidably receive the body of the probe for movement into and out of the pipe, a relatively deformable and compressible ferrule encircling the probe body movable into abutting relation to an annular seat provided on the end of the collar remote from the welded end thereof, and a compression nut adapted to be screwed onto a threaded end of the collar adjacent the seat and cooperate therewith and with the ferrule therebetween to crimp the latter tightly around the probe thus sealing the probe in a fixed operative position, the improved positive lock which is characterized by adding an externally-threaded male extension to the compression nut, providing the probe body with a fixed abutment-forming projection exposed beyond said ext
