Liquid flow sensor questions

$

Hello,

I am working on developing a project for my PhD, and I am a beginner to Arduino. As a part of this project, I need a liquid flow sensor. I originally thought that I would not need to measure more than 1 l/min of flow, but I found a paper that suggested that I should be able to pump at least 1.3 l/min. I have found a few liquid flow sensors, and I was wondering if anyone has any experience with any of these or has recommendations on which one of these or other options out there to use?

For this project, I was originally considering the Sensirion SLF3S-4000B Liquid Flow Sensor; however, it can only go up to 1 l/min, and even at that, with only 20% accuracy at that high of flow according what I read in the datasheet (they also have an Arduino code library available that makes it easier to work with).

Looking around further, I found the Renesas FS1023 Liquid Flow Sensor Module. The datasheet says that it can measure from 0–3 l/min, and a typical reading accuracy of down to 2% according to Mouser and Digi-Key. However, the whole family of sensors is obsolete and thus they are limited in availability, and I can't find any meaningful Arduino code for them.

I have also come across the OOL Thermal MassFlow Sensor. The datasheet says that it can measure from 0–3 l/min, and a typical reading accuracy of 3% of measured value (depending on electronics and calibration). There is also an OOL Sensor Evaluation Kit available that makes integration easier, and it appears to be an analogue output (datasheet). However, I can't find any Arduino code examples or tutorials to work from for this sensor.

Any advice on sensors or where I can find Arduino code to learn from for these sensors? Thanks!
