Abstract: The process of flowrate metering and calibration is more complicated, so the folwrate computer at present are widely adopted for the data aquisition and processing. Although the manufacturers are possessed of the set of flowrate computers and flowrate metering unit, the users generally use their own SCADA systems to monitor meters instead of purchasing the dedicated flowrate computers in order to avoid investment, the problem that the flowrate metering unit allocates with SCADA system are proposed. Taking the oil metering control system on Kurla-Shanshan oil pipeline as an example, two allocation programs are proposed.
