sub metering

Johno12345
Hi,


It's me again. I'm looking at sub metering a largish installation, not for revenue. I know what I want but it seems surprisingly elusive.


I rather expected to be able to buy a set of CTs and a meter without a display etc that would sit inside a dis board or isolator etc, and connect via ethernet, either wired or wireless (perhaps) to a server on site where i can view real time data, and generate reports of where the energy is being used. I also thought id find a version with a pule input for water meters etc. 


but so far, speaking to companies, I'm being offered modbus systems, which are ok, but need modbus converters, or full blown smart meter installs back to a central server somewhere. All these suggestions are thousands and thousands just for a handful of meters (I want about 30)


Has anyone come across something as simple as what I describe?

    Hi 

    LoRaWAN installations can be quite a bit cheaper than Modbus and with much more scope for adding additional devices later if needed. Also being wireless this greatly reduces the install costs.


    You can add a Pulse to LoRa converter to each meter and a single gateway to pick all the meters up. These can then be managed from a web based platform and text/email alerts set up if needed. Only one power supply is needed for the gateway and you can use either a GSM, ethernet or combined gateway.

    Thanks for that info, I had heard of LOWRA but thought it was Laura, so would never have found it.


    The reason I wasn't keen on that was because it relies on a web platform, and therefore subscription, and a third party

    I cant help you but you may get more answers in the wiring part of the forum - this section is not frequented so much by the electrical types - if you 'report' yourself to the mods they can move it for you

    mike.
