Dario:

This EDN article may give you some ideas using transistors ... idea is
reasonable and could be updated to minimize popcorn parts.

Subject: [PIC] Measuring flow using a temperature sensor (and maybe a
heater)

We've been considering measuring air flow (at some 1-2 bar) by using a 
temperature sensor (possibly a I2C one such as MCP9800) and maybe a 
heater coupled to it.

Do you think it's doable with some good precision? Of course the other 
method would be using a fan or alike and an encoder but it's quite more 
complicated... :)

thanks for any tip!
