Hydronic Data Logging

Constantin Member Posts: 3,796
... not only can you attach a huge range of sensors to it (temp, power consumption, on/off, etc.) but the Web Energy Logger also has a built-in COP calculator that you and the customer can admire on the web.

The only requirement is a web-connection as the logger uploads its data set to the server every couple of minutes. You can download the datasets if you like. The server can be set up graphically show the temperature, humidity changes, as well as current status (i.e. pump on/off, temps, runtime, monthly runtime, etc.)

Given that this system does not cost that much more than the HOBO and yet can read many more inputs, this is what I would buy. Plus, the WEL consumes much less power than a PC that you'd have to leave running 24/7 with some of the data loggers out there. See ourcoolhouse.com

    I just googled \"Data Logging\" equipment...

    and was a bit overwhelmed.

    I will need to sort through all of the information but maybe some of you can help.

    Is there a data-logger that would have an integral outdoor sensor to gather degree day information AND measure therms used so that we can "Plug-n-Play" a USB or firewire (or infrared for that matter) port and download all of the info to get (EDIT:)"BTU's and therms per degree day".
    If I am doing a geothermal unit, I would have a meter on my GSHP so that I am only reading electrical consumption as it pertains to heating load.

    With all of our efficiencies and technology, I would like to have the ability to say definitevly that this is the amount of fuel used and how efficiently it was used.

    contact the folks at Onset

    I use their HOBO temperature logger. They always have a booth at the trade shows and are very approchable and helpful. I'm sure they would be glad to talk over your needs.
