Watflow DN15 Water Meter,Measuring in Cubic Meter, Cold Water Meter for Garden or Home,1/2" NPT Couplings

I have this on my rainwater plumbing system that feeds my house with captured rainwater. The water is pressurized in a well water pressure tank via a shallow well pump. Then the I have the water line run from the pressure tank through some filters and this meter to the house. I installed it with a bypass loop in case it needs servicing so I can keep water going to the house if I have to remove it. It just ticked over the first cubic meter of water passing through it. I made sure to note they date it was installed so I can keep track of the water usage over time. I did have a leak after I installed it that came from one of the gasket rings that seals the brass union fittings that come with it. Turned out the gasket wasn't seated correctly and got pinched. I was able to solve it by undoing it and placing it correctly before tightening. After that I had no leaks. It's been working well so far, and I haven't noticed any drop in flow to the house since adding it. If you're familiar with basic plumbing it is very simple to install but I definitely recommend adding a bypass loop so it can be bypassed if needed. I'm pretty happy with it and looking forward to tracking how much water gets used in my rainwater system.
