Thermal Mass Gas Flow Meter
A thermal mass gas flow meter measures low flow rates of gases using heat transfer principles, often in clean rooms or semiconductor manufacturing. It operates by heating a sensor and measuring the cooling effect of the gas flow. This instrument falls under tariff item 9026.80.00 as an 'other instrument or apparatus' for measuring or checking the flow of gases.

Import Tips & Compliance
• Confirm the meter is not designed for automatic process control; if it only measures flow, classification under 9026.80.00 is correct
• Provide technical data on the measurement principle and gas compatibility
• Verify if the device meets Canadian cleanroom standards if used in semiconductor fabs
