AI Technical Summary
Existing technologies lack effective methods for stability verification and contamination detection of sulfur-containing natural gas metering systems, leading to inaccurate metering, especially as elemental sulfur particles aggregate with other solid particles in the pipeline under changes in pressure, flow rate, and temperature, forming deposits that affect the metering system.
A detection device for a sulfur-containing natural gas metering system is provided, including a flow verification component and a contamination detection component. The device measures the flow rate using an ultrasonic probe and detects the material distribution inside the pipeline using a capacitive chromatography membrane sensor array. The device is combined with a processor to perform stability verification and contamination distribution analysis.
It enables stability verification and contamination detection of sulfur-containing natural gas metering systems, ensuring the accuracy and long-term stable operation of the metering systems, and timely detection and cleaning of contaminants in pipelines.
