The application discloses a method, device and storage medium for determining the working performance of a working standard device of a circular turbine, belonging to the technical field of natural gas metering. In the present application, the accurate value range is determined by transmitting the plurality of first-type flow rates monitored before the current time of the turbine and the plurality of second-type flow rates monitored by the loop turbine working standard device before the current time. That is to say, the accurate numerical range is determined through big data analysis according to historical detection data, so that the determined accurate numerical range is obtained after optimization based on historical monitoring data. Therefore, it is more accurate to determine the working performance of the ring turbine working standard device by acquiring the first flow rate and the second flow rate, and according to the difference between the first flow rate and the second flow rate and the range of accurate values.
Description
technical field [0001] The present application relates to the technical field of natural gas metering, in particular to a method and device for determining the working performance of a loop turbine working standard device. Background technique [0002] Usually, in the process of natural gas real-flow verification, in order to ensure that the working standard device of the ring turbine is 0.5 standard, it is necessary to determine the working performance of the working standard of the When the user's flowmeter is verified, the accuracy of the loop turbine working standard device. [0003] At present, the ultrasonic flowmeter is usually connected in series with the working standard device of the loop turbine in a one-to-one manner, and then the monitoring value of the ultrasonic flowmeter and the monitoring value of the working standard device of the loop turbine are checked in real time, and the ultrasonic flow rate is regularly analyzed and judged By analyzing the differenc...
