Main Question or Discussion Point

Hi,

I'm working on a project that uses a mass air flow sensor. It outputs a signal in hertz which relates to grams per second.

I am trying to create a formula that I can use to easily convert the Hz to G/s.

I have only been able to get a few samples of information to assist in the creation of the formula.

Is it possible to generate a formula from these data points?

Note: some of this data may be off by a few percent.

G/s Hertz
0 1700
2.75 4300
5.8 5680
3.97 4880
3.7 4800
6 5800
10.2 7150
12.4 7800
2.8 4300
3.1 4500
2.75 4300
13.53 8200
15.6 8800
22 9800
26 10500
28 11000
35 12100
44 13000

Any help is appreciated

I have put it into a graph in excel. But I'm not to sure where to go from here.

A good start would be to add a linear trend line, use the formula for the trend line as your model.
