Abstract

See full text

A pipeline system of a process facility has a plurality of equipments, the equipments including at least one pipeline for providing a channel for a fluid of a process to flow. The process of the process facility is controlled by a process control system. The equipments also include at least one device for measuring a process variable of the fluid. The device comprises a sensor element for sensing a predetermined process variable of the fluid flowing in the pipeline to output a signal containing information about the process variable being measured and containing information about the fluid flowing in the pipeline. The device further includes a first filter to pass a first component of the signal containing the information of the process variable and a second filter to pass a second component of the signal containing the information about the fluid flowing in the pipeline. A first processor processes the first component of the signal to output the process variable to the process control system to control the process. A second processor processes the second component of the signal in a flow model of the pipeline system to output advisory information indicating imminent failure of the equipment when detected by said processing by the second processor.
