Record in TXT flows using a vortex principle flow meter

Using Arduino Project Guidance
1

Hello.
I'm trying to program a arduino device to record in ssd card into .txt values within 1000 ms intervals, values from a flow meter using vortex principle, a SV4204 flow meter. I found lots of tutorials about some flow meter using a rotating flapper, but they use some formula that surely I can't apply on my case.
There is a wire that outputs the flow and I tought maybe there would be a way to atribute that wire signal to a variable and then covert it to numerical value.. is that possible?
any sugestions?

the specs of my flow meter are here

@jopereira, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project :wink: See About the Installation & Troubleshooting category.

The sensor has a current loop output, 4 to 20 mA. Let that cuurent pass through a 220 ohm resistor, for a 5 voltcontroller and measure the voltage...
