Abstract
A technique for calibrating a fluid flow sensor includes generating fluid flow at a first speed. A first temperature of the fluid flow is determined using a first temperature sensor that is positioned upstream of the fluid flow sensor. A first power is supplied to a main heater of the fluid flow sensor to adjust a second temperature of a first plate of the fluid flow sensor to be substantially equal to the first temperature, A second power is supplied to a guard heater of the fluid flow sensor to adjust a third temperature of a second plate of the fluid flow sensor to be substantially equal to a fourth temperature of the first plate. The first and second plates are separated by a spacer and the first speed and the third temperature provide a calibration point on a calibration curve for the fluid flow sensor.
