Live duct schematic — airflow through the filter

Air moves left→right; particle rate & speed track the airflow estimated from the measured ΔP. Sense taps P₁/P₂ read the differential the sensor sees.

Measured ΔP & temperature over time

Filter ΔP (in.w.c.) Air temp (°F) real sensor readings
Live ΔP and temperature are real sensor measurements. Airflow (CFM), filter loading, and life estimates are physics-model figures derived from the measured ΔP. K&H Sensor Solutions.
