Abstract

See full text

There is described herein a flow sensing device having offset compensation and an offset compensation method, the flow sensing device having two separate and independent thermal flow sensors, each containing a heater and at least one temperature-sensitive element. The components of the two thermal flow sensors are connected such that flow-dependent contributions of each sensor into a common output signal have opposite signs after passing through a subtracting node. Heating pulses are applied to the heaters of the two thermal flow sensors out of phase, and an output signal is measured for each heat pulse applied. A net output signal is then determined by calculating a difference between a last output reading and at least one previous output reading.
