GPI TM100-N Water flow meter

Description

Don't ask me any questions about its use as I am no plumber. If you are looking for this then you know way more than me about it.
Inherited it from a plumber friends estate. As you can see from the last photo this item sells for 0+. Others on ebay asking for 0+! I am selling it for much less here. It is in brand new condition in the box and you can see from the photo it is displaying information on the screen.
Please be sure you know what you are buying as I do not accept returns.
