Abstract:
1. A flow diagnostic system adapted to couple to a primary flow sensing element via impulse lines, the flow diagnostic system comprising: a pressure transmitter coupled to the impulse lines and generating digital pressure data representing pressure; a control system receiving the pressure data and providing the pressure data to a diagnostic application stored in the flow diagnostic system, the diagnostic application including: a first algorithm calculating a difference between the pressure data and a moving average of the pressure data, the moving average based upon weighted pressure data, and a second algorithm receiving the difference and calculating a trained data set of historical pressure data during a training mode and calculating a current pressure data set during a monitoring mode, the set of historical pressure data comprising statistical data as a function of the difference and the current pressure data set comprising statistical data calculated as a function of the difference, and the second algorithm further generating diagnostic data as a function of the current pressure data set relative to the set of historical pressure data indicating changes in a condition of flow sensing, and a third algorithm generating a report indicating the diagnostic data.
