3/4” Water Meter: Lead Free Brass, NSF Certified, Multi-Jet, Gallons (Horizontal Installation)

I needed a NSF certified water meter for a rental. I was impressed how well it was made, solid brass alloy and it seems very accurate. It states that the only thing touching the water is the impeller, I can't see it but I think that is a good engineering design.

Works well on a cooling tower make up water application

Excellent product

Works well, a lot of plastic in the dials but, it works and that is what I wanted.

Exactly as advertized. High quality build that was very easy to install. It is NSE certified and conforms with lead-free plumbing as defined by California. These certification sold me on the product because other products did not have these certifications. Using it for home automation to watch water usage and flow rates as every gallon produces a tick.It comes with 2 unions that screw into a 3/4 female pipe. The meter is easily connected between the 2 unions.

Heavy duty construction. Built to last a long time.

Installed per manufacturer specification. The small meters spin as they are supposed to, but it doesn't calculate on the main gallons reading. It was shipped with it slightly off zero and it hasn't moved from there after a week of use. It's been too long to return, so I will likely remove and bypass and melt this junk off metal down in the crucible. Not worth the money.

I installed this water meter in our pump house to keep tabs on the water we will use to irrigate this summer. It was really simple to install, and the way it is designed with the threaded couplings means you can really easily remove it if it needs to be replaced. I ordered the 3/4" model, which is a slight reduction from the 1" pipe I installed it on, but it does not seem to reduce the flow rate appreciably. The accuracy seems to be more than enough for the sort of measuring i intend to do- as mentioned by another reviewer it comes with a graph that shows the % error as a function of flow, and it peaks at just over 1%. The main "odometer" part reads the hundreds of gallons, then it has a series of dials to read off the 10s, 1s, 1/10ths, and 1/100ths of a gallon. Once i hooked it up I recorded the reading, and then filled a milk jug up from a hose and got a final reading that was within a couple of 1/100ths of one gallon. Seems like it should do the trick.
