I'm searching for a good water flow meter to add to my home controller project with Arduino. I have been searching in several pages and I only found some devices that work for low flow. I need to control the water usage in my home and I thought to add a flow meter at the point where the water enters my home, and view the data with Arduino.
Do you have experience with any flow meter with good quality?

Don't you have a water meter in your house. These units can be read quite easily. Some have a rotating magnets, or like mine, a rotating dial with a large reflective surface.Gerben– Gerben2015年12月17日 16:04:25 +00:00Commented Dec 17, 2015 at 16:04

I have, but not in my house. I'm living in a flat and flow meters they are in a room that I don't have access easy.Juan Antonio– Juan Antonio2015年12月17日 21:16:45 +00:00Commented Dec 17, 2015 at 21:16

1I have a similar situation with my power meter not being in my apartment. I have an Arduino running on batteries, and sending the data wireless to an arduino in my apartment. If this isn't possible, I'd just buy a second water meter, similar to the one outside your apartment. Those units are made exactly for your purpose. I wouldn't want to risk having a water leak.Gerben– Gerben2015年12月18日 13:24:56 +00:00Commented Dec 18, 2015 at 13:24

1It would help to know more about the meter that you need – can you tell us the size of the pipe going into your flat where you would attach the meter and give us a rough idea of the flow rate that you need?dlu– dlu2015年12月18日 21:55:07 +00:00Commented Dec 18, 2015 at 21:55

I don't know how is the size of pipe, but I think that it isn't too significant. I always can buy an adapter. But the most important, the flow rate, well, I don't know how to size this. This is a normal house, we have only a bathroom. I found a project in the net in which some guys uses this flow meter: Koolance INS-FM17N. His flow rate range is 1.0-15LPM. I think that 15 litres per minutes is quite and enough, but i don't sure. What do you think?Juan Antonio– Juan Antonio2015年12月19日 19:43:24 +00:00Commented Dec 19, 2015 at 19:43
1 Answer 1
I've used an arduino with an irrigation flow meter.
I think I'm getting accurate results, but I haven't checked against a bill. It can handle high flow, and the sensors will attach to any size pvc line. The sensor are a bit expensive, however. 150ドル for the sensor and 35ドル for the T junction that it plugs into.
However, as you are living in an apartment, you'll probably need a non-invasive sensor. Perhaps an acoustic one.
