PROVING LIQUID METERS WITH MICROPROCESSOR BASED PULSE OUTPUTS Class #2420.1

摘要

The advent of microprocessor driven flow meters in the late 1960's and early 1970's was heralded as a new frontier in flow measurement.Little did we anticipate the unintended consequence of adopting these new technologies,or how our conventional verification techniques would be challenged? We are still playing catch-up in the realm of flow meter verification where"manufactured"or,computationally derived flow meter pulse outputs,are concerned.
