20150075293 | CUSTOMIZABLE AVERAGING PITOT TUBE PROBE AND PROCESS VARIABLE TRANSMITTER - A customizable length averaging pitot tube (APT) probe for insertion into a confined conduit, such as a process pipe, is disclosed. The APT probe includes a probe portion, configured to be inserted into the confined conduit, which includes longitudinally extending upstream, downstream and middle surfaces to form first and second fluid carrying plenums within the APT probe portion. A plurality of longitudinally arranged openings are disposed along the length of the upstream surface with each opening in fluid communication with the first fluid carrying plenum. A plurality of longitudinally arranged openings are disposed along the length of the downstream surface with each opening in fluid communication with the second fluid carrying plenum. A cap is affixed to an end of the APT probe portion to isolate the first and second fluid carrying plenums at the end of the APT probe portion. An elongated body is coupled to the APT probe portion and provides fluid passageways fluidically coupled to the first and second plenums for coupling process pressures from the first and second plenums to a pressure sensor. | 03-19-2015 |
20140260671 | PITOT TUBE TRAVERSE ASSEMBLY - A pressure measurement system for measuring pressure in a conduit has a bluff body extending into the conduit. The bluff body has an upstream opening and a downstream opening. An upstream pitot tube is slidably engaged within the bluff body and has an open end positioned in the upstream opening. A downstream pitot tube is slidably engaged within the bluff body and has an open end positioned in the downstream opening. A differential pressure sensor is fluidly coupled to the upstream pitot tube and the downstream pitot tube to measure a pressure difference between the upstream pitot tube and the downstream pitot tube. | 09-18-2014 |
20140260670 | PROCESS VARIABLE MEASUREMENT USING PRIMARY ELEMENT CONNECTION PLATFORM - An apparatus for measuring a process variable of a process fluid based upon a process variable sensor measurement, includes an elongate spool that provides a spool conduit therethrough adapted to be coupled in line with process piping to receive a flow of process fluid. A meter body is carried in the elongate spool and receives the spool conduit therethrough. The meter body has a primary element opening which extends from the spool conduit to outside of the meter body. A carrier is configured to removably mount to the meter body and includes a primary element in the spool conduit through the primary element opening. A process variable transmitter is coupled to the primary element and is configured to measure the process variable of process fluid. The meter body is preferably configured to receive different types of primary elements carried on the carrier. | 09-18-2014 |
20140260657 | PROCESS VARIABLE MEASUREMENT USING UNIVERSAL FLOW TECHNOLOGY CONNECTION PLATFORM - An apparatus for measuring flow of a process fluid includes an elongate spool providing a spool conduit therethrough adapted to be coupled in line with process piping to receive the flow of process fluid. A meter body is carried by the elongate spool and receives the spool conduit therethrough. The meter body includes a flow measurement component opening which extends from the spool conduit to outside of the meter body. A flow component is configured for placement in the flow measurement component opening of the meter body. A carrier is configured to removably mount to the meter body and couple the flow measurement component to the spool conduit through the flow measurement component opening. A flow measurement transmitter couples to the flow measurement component to measure the flow of process fluid based upon an interaction between the process fluid and the flow measurement component. | 09-18-2014 |
20130327157 | PROCESS FLUID FLOW TRANSMITTER WITH FINNED COPLANAR PROCESS FLUID FLANGE - 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. | 12-12-2013 |
