Methods and an internet of things (iot) systems for vapor-liquid identification based on vortex flow sensors

An Internet of Things (IoT) system for vapor-liquid identification based on a vortex flow sensor, comprising a management platform and a perception and control platform, wherein the management platform is configured to:

• determine a spectral feature of each location point based on vortex signal data of the each location point within a target pipeline network;
• determine a steam feature of the each location point based on the spectral feature of the each location point;
• determine at least one first location point based on the steam feature of the each location point, wherein
• the at least one first location point includes a location point where wet steam occurs;
• and
• generate a dehumidification instruction based on a steam feature of the at least one first location point, and send the dehumidification instruction to a first automatic steam trap of the perception and control platform, wherein
• the first automatic steam trap is configured to adjust at least one of an opening degree or an opening frequency based on the dehumidification instruction.
