Flow meters delivering inaccurate data is an economical and costumer relation concern in most areas of application where flow meters are key components for billing. Solution to this have so far been improved standards and schemes to implement and maintain such standards for the life time of the flow meter. In contradiction to quality standard comes the flow meter self-diagnostic solution. Here the flow meter it self is capable of diagnosing the magnitude of its own metering error. It can then issue an alarm or even better impose corrections thus reducing the metering accuracy to an acceptable level. This paper will discuss strategies for obtaining self-diagnosis and show some resent on-going work going towards self-diagnosing or even self-correcting flow meters. Indicating that real intelligent flow meters is a possible future.
