This guide is to show the setup of a water meter with a pulse output. I will be using the pulse input on an EmonTH in this guide but there is no reason the setup will not work with other products in the OEM family that have a pulse input e.g. (Emonpi, etc).
My reason for using the EmonTH is the location of the meter and the pulse input on my Emonpi already being used for monitoring a gas meter (Guide to follow for this too).
Things you will need, where I got mine and costs.
