Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal.

I just need a flow meter that only works with water. I want the flow meter to be disabled when only air comes through the meter, is that possible?
This is somewhat possible in software. In almost any application I can think of, the flow of air will be much higher than that of water. So you disregard data when there's a rapid jump in the flow rate. If this does not work for you, apply a water sensor before or after the sensor, and adjust your code to monitor that.
Hi! I am going to buy 100-200 pss of this meters but with 3/4 inch connections. Do you have it? Or may be you planing to sell with 3/4 soon?

This products looks like what I need but I need two sizes, this 1/2" size is one but I also need 3/4" as well. Is a 3/4" size to be made available soon?
Also, what thread size does this have?

I am looking at the G1/2 water flow sensor.
I believe this is exactly what I need except I need 3/4 inch inside diameter water flow sensor at low cost per unit.
Is this something you can provide or suggest a supplier?
thanks,
Mac
