Hold it close to where the meter and the register join, this is where the magnetic field will be strongest. To test this, hold a compass next to the water meter. Since the wheel has magnets attached to it, the magnetic field from the magnets will almost certainly be detectable from the outside of the water meter enclosure. So to measure water flow, you just need to monitor whether this wheel is spinning, and how fast. This magnetic drive between the water meter and the register is used in virtually all residential water meters. The register is the part that sits on top of the water meter, analog or digital, that shows you how many gallons of water you have used. When water is flowing through the meter, this wheel spins, driving the register. This type of water meter design usually incorporates a wheel, as part of the internal mechanism, with one or more magnets attached to the wheel. The most common water meter type that is installed by local municipalities is a positive displacement water meter. First, let's take a look at what is going on inside a typical residential water meter. The solution described here is non-invasive, uses your existing municipal water meter, and the total project cost can be kept under $5-10. If you'd like to monitor your water usage, as part of a DIY smart home automation and monitoring project, then this instructable might help you to achieve that goal.
