Flow Sensor Silicon Chip from United States
A thermal mass flow sensor chip that uses semiconductor-based heater and temperature-sensing elements to measure fluid flow by detecting heat dissipation. It is a semiconductor-based transducer because it converts a physical phenomenon (flow) into an electrical signal, and it is supplied as a bare die or packaged component for integration into medical or HVAC equipment.

Import Tips
• Confirm the chip is a semiconductor-based transducer and not a complete flow meter with a housing and display, which would fall under another heading
• Provide technical documentation showing the sensing principle to support classification
• If the chip includes a microcontroller for signal conditioning, consider whether it is an integrated circuit under 8542
