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.
Claims22
A system comprising:
- 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;
- wherein the SCADA system is configured to perform a validation on data provided by the flow computer regarding fluid flow;
- wherein the flow computer is configured to perform the validation on the data regarding fluid flow, and if the validation is successfully completed by the flow computer, the SCADA system refrains from performing the validation.
A flow computer comprising:
- a processor;
- and
- a memory coupled to the processor;
- wherein the processor is configured to couple to transmitters associated with a metering tube, to perform fluid flow calculations to create fluid flow data, and to store the fluid flow data for later transfer to a supervisory control and data acquisition (SCADA) system;
- and
- wherein the processor is configured to perform a validation on the fluid flow data prior to transfer of the fluid flow data to the SCADA system, and if the validation is successfully completed by the flow computer the SCADA system refrains from performing the validation.
A method comprising:
- reading values of differential-pressure caused by fluid flow through an orifice of a metering tube, the reading by a flow computer operationally coupled to the metering tube;
- storing on the flow computer the values of differential pressure to create raw data;
- calculating by the flow computer instantaneous flow values through the metering tube based on values of differential pressure;
- calculating by the flow computer an accumulated fluid flow value based on the instantaneous flow values;
- and
- validating by the flow computer the accumulated fluid flow value using the raw data;
- and if the validation is successfully completed by the flow computer
- refraining from performing the validation by a supervisory control and data acquisition (SCADA) system coupled to the flow computer.
A non-transitory computer-readable medium storing a program that, when executed by a processor, causes the processor to:
- read data values from transmitters associated with a metering tube;
- calculate instantaneous flow values based on the data values;
- accumulate the instantaneous flow values to create accumulated flow value;
- provide the accumulated flow value to a supervisory control and data acquisition (SCADA) system upon request from the SCADA system;
- and
- validate the accumulated flow values using the data value, and if the validation is successfully completed by a flow computer the SCADA system refrains from performing the validation.
