Embodiment Construction

[0021] The disclosed embodiments provide a paddle style orifice plate design with embedded impulse lines that allow a process variable transmitter to be mounted on the shank of the orifice plate. This configuration allows omission of other components or fabrication / installation steps typically required for paddle-style orifice plates, such as fitting flanges, separate impulse lines, and instrumentation manifolds.

[0022] figure 1 is a simplified diagram illustrating an industrial process control or monitoring system 100 for monitoring or controlling a process fluid in an industrial process. Typically, field devices such as process variable transmitters 102 are located at remote locations of the facility and transmit sensed process variables back to a centrally located control room 104 . A variety of techniques can be used to communicate process variables, including wired and wireless communications. One common wired communication technique uses what is known as a two-wire p...

Abstract

A differential pressure fluid flow meter element for insertion between connecting flanges of a conduit section of a fluid carrying conduit, the flow meter element comprising a flat orifice plate having a A fluid contacting region is positioned in fluid flow through the conduit, and a handle extends outwardly from an exterior of the fluid contacting region. The flat orifice plate includes at least one pressure port formed in a fluid contact region of the flat orifice plate, and at least one impulse line channel formed in the flat orifice plate and extending from the One of the at least one pressure port extends through the shank to a corresponding transmitter interface port. A plurality of orifices formed in the shank and arranged and positioned relative to the at least one transmitter interface port allow for the direct mounting of a process variable transmitter to the paddle style orifice plate shank wherein the transmitter is substantially vertical on the plane of the handle.

Description

technical field [0001] The present disclosure relates to an industrial process control or monitoring system. More specifically, the present disclosure relates to a paddle-type orifice plate and a process variable transmitter that uses a paddle-type orifice plate to measure a process variable of an industrial process. Background technique [0002] In an industrial environment, control systems are used to monitor and control inventories of industrial and chemical processes, etc. Typically, control systems that perform these functions use field devices that are distributed at key locations in the industrial process and are coupled through process control loops to control circuitry in the control room. The term "field device" refers to any device that performs a function in a distributed control or process monitoring system, including all devices used in the measurement, control and monitoring of industrial processes. [0003] Some field devices include transducers coupled to ...
