Mass flow sensor

Simon:
i think they are doing somthing along the lines of removing the ambient air temperature "offset" with this configuration. Instead of putting the amplifier reference at at 0 and measuring the full input swing and thus loosing small voltage measurements with high resolution they are basing off the current ambient.

It's hard to explain and this is by no means a complete diagram. You would need more of the circuitry to see what they are doing.

This is their whole schematic.
I don't see the thermistor being used to correct anything here except provide a temp output.

Gyro:
The schematic says "wind sensor", not MAF?

Simon:
Just get an off the shelf sensor. Your local auto parts place will sell you one for around £50 which is not a lot when you think of the complexity it resolves.

An article about it terms it as MAF https://www.electroschematics.com/11900/measuring-air-flow/
