Looks AWESOME @though! 
Are the connectors to the meter copper shark bite type fittings?
@SDR - the wireless flow meter is made out of ABS (not PVC) plastic. The Shark bite connectors can be used to join that to copper pipe. I used the Orbit PVC Lock connectors to connect my flow meter to the PVC pipe in my installation.
what is the purpose of the shutoff valve after the flow sensor ??
looks good, thanks for sharing. my setup is 1" copper, should be easy enough!!
@JS_racer, yes yours will be a piece of cake.
The reason for the shutoff is, that’s the only 1" PVC to 3/4" copper fitting that Sharkbite made at the time. Probably still is…
Got ya, thanks
Say, is the 1 inch copper Id or od?? My I’d is larger than a 1 inch wrench, didn’t measure exactly how big, 1.25?
