Being a physician I´m in the middle of a project. I want to measure air flow using a turbine. Outout will be more or less a square wave with frequency of up to 200 Hz for flow rates up to 10 L/s. My problem is that frequency will not be linear to flow and that the propeller in the turbine will have inertia that has to be taken into account. I haven´t got a decent clue about how to proceed. Is it possible to set up a schematic algorithm for this, including a factor for linearity, one for some unlinearity and one for inertia? I have the "correct" flow signal for various flow patterns so I can do the simulations by calculations only.
I´m not shure this is the right forum, and even less the right section. Please point me in some direction
