I want to read a 4-20 mA analog signal from a 24V flowmeter. I've read the simplest way is to convert it into 1-5V signal using a 250 ohm resistor. The thing is I want my reading to be precise so my question is; is there any resolution loss when converting it to 1-5V?
I've also looked up on current to voltage converting boards similar to this one: https://www.sparkfun.com/products/14544
but I don't think they can detect 4mA signal.
I am a beginner in this so need some guidance here.
