Abstract: A method and system of validating data regarding measured hydrocarbon flow. At least some of the illustrative embodiments are systems including a flow computer coupled to a metering tube and configured to measure fluid flow through the metering tube, and a supervisory control and data acquisition (SCADA) system coupled to the flow computer. The SCADA system is configured to perform a validation on data provided by the flow computer regarding fluid flow. The flow computer is configured to perform the validation on the data regarding fluid flow, and the if the validation is successfully completed by the flow computer, the SCADA system refrains from performing the validation.
