Thermal Mass Air Flow Sensor – Constant Temperature Anemometer

https://www.electronics-lab.com/project/thermal-mass-air-flow-sensor-constant-temperature-anemometer/

The CTA mode (Constant Temperature Anemometer) consists of a simple feedback circuit for temperature regulation of the heater on the flow sensor and, as flow speed changes the thermal energy loss by the heater changes. By adapting controllers, a constant temperature difference between the heater and the temperature sensor can be achieved. The supplied electrical […]
