Whats the Pulse Output for?

If you wish to digitally or remotely monitor and record your usage you will require a meter with a pulse output. These can be directly connected to a digital display or you can connect to data acquisition equipment.

Australian domestic pipes are either 1/2" or 3/4" - Please ask your plumber.

Do the meters come with both brass unions?

Yes! All our meters come with suitable 1/2" or 3/4" brass unions (male).
