Open the CIPO recordAbstract From the Canadian patent
A fluid flow meter (82) diagnoses the condition of its primary element (28) or impulse lines (30) connecting to a differential pressure sensor (31). A difference circuit (90) coupled to the differential pressure sensor (31) has a difference output representing the sensed differential pressure minus a moving average. A calculate circuit (92) receives the difference output and calculates a trained output of historical data obtained during an initial training time. The calculate circuit (92) also calculates a monitor output of current data obtained during monitoring or normal operation of the fluid flow meter (82). A diagnostic circuit receives the trained output and the monitor …

Why it's free to use
- Filed February 24, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 24, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
