Investigation of Thermal Anemometry with Thermistor Sensing Elements for Gas Flow Measurements in Harsh Environments

The production of high-quality steel requires purging with argon to remove impurities, degas the molten metal, and optimize alloying process. However, sealing challenges in steelworks result variable losses. But accurate mass flow measurements are crucial for process optimization. This work investigates feasibility a ladle-based sensor system overcome these challenges. must address high gas velocities, wide fluid temperature range, limited power availability. study focuses on thermal anemometer thermistors as sensing elements, evaluating sensitivity, cross-sensitivity, consumption test rig.
