Gas flow meter

Using Arduino Sensors
1

Hello guys,

I have a project where I need two things:

  1. Use a gas flow sensor for Arduino between my gas tank and my system, in which I will try to control the flow rate of the gas and I want to measure the total volume of gas added to my system. The gas is CO2 and the problem is that my flow rate is low. I want to work with a flow rate of 30 ml/min approx. I cannot use a water flow sensor because I think it would be inaccurate. What you guys think?

  2. I also want to use a gas sensor to measure the total volume of gas that comes out of my system. In this one it is not necessary to measure the flow rate.

Basically the output volume will be less than the input volume, and I want to measure this difference using the two sensors.

So, my scale is not liters per minute, but milliliters per minute. Is that possible to have this kind of precision using those kind of sensors? Any suggestions?

Thanks in advance!!

A very large selection of flow sensors is available for gases. Google will help you find the appropriate one.
