Mavro,

I am trying to buy these at the moment from Europe –

They work with RFXCOM and send 1 pulse per 1/2 litre I believe. I too have TED and now want to add water and gas too.

I am arranging a shipment over for myself and 1 other – if you interested let me know

I like this but this isn’t a usage meter but a flow meter. I have been using mechanical meter from watermeters.com but they are analog and do not have any facility for monitoring except good old pen and paper for logging!

Take a look at these flow totalizers:

Middle of the page. They have different options available to connecting to the output.

Troy,

Good stuff! Thanks for the info. Have you used any of them?

CoolPoint has a unit that totalizes.

The nice thing about this product is that it is industrial quality and has no moving parts. Products used in homes typically are cheap and inaccurate and need maintneance. This is not true of the CoolPoint totalizing meters. You get what you pay for.

I used one several years ago but not for automatic data acquisition. We used it to fill out a sheet by hand. I was searching for a totalizer that would be compatible with acetone. Most are not. I bought one (don’t remeber which) that listed the wetted parts. The parts listed generally are compatible, but eventually (after a year or so) the unit failed. But the specs did NOT list the unit as compatible with acetone (my bad, I was taking a chance).

Did you look at the Neptune (www.neptunetg.com) water usage meters and their tracking hardware/software? I’m looking around also, just started…

Great! Thank for information, I’m looking for it for a long time,
