While going through the different forum topics I see a lot of people having issues with 3phase networks without N.
Using the clamps works fine as long as 1 wire is consistently used as N, but most people have some device (cooker) connected as 3 phases or the load is balanced over the 3 phases rather than 2+N
While googling I found these ABB meters ODIN OD4165 and OD4110 that seem to measure the consumption of 3 phases correctly and seem to have pulse output. Would it be possible for me to install one of these and connect it to the Flukso.
Here is a link to the ABB devices http://www05.abb.com/global/scot/scot349.nsf/veritydisplay/0a4b318e8e4b1be8c1257567004961e3/$file/2cmc480022c0002_b_en_electricity_meters__din-rail_mounted.pdf
Are there any alternatives/similar devices to these ABB meters that would do the trick. I do like the idea of the device being a DIN rail device, keeps it very organised and clean.
Thanks
According to http://www.jan-karina.be/zonnepanelen/ODIN_Meter_OD4165.pdf the OD4165 does measure on three phases but puts out the sum signal via S0/LED; so distinguished measuring of three phases seems not possible with this meter (what was the actual requirement for three separate clamp measurement...)
Or did I oversee something?

a lot of these grids are 130/230V (130V from phase to earth)
then you can use 3 clamps and set the voltage to 130V
Not really, 3 clamps work if you have 3 phase + N setup, not in a 3 phase without N (which I have). There are multiple articles in the forum discussing this.
I'm not interested in the individual load of the phases, just want something that will monitor water, electricity and gas and solar panel electricity generated.
So was wondering if this would work if I use such a Din rail energy meter (was surprised this was not suggested in the multiple posts where the 3phase problem is discussed, so I must be overlooking something ;-)
Looks like a good idea . ;)
I would always recommend using a DIN rail meter if you don't mind installing it (and have done so in several threads)....
The clamps are interesting because they are easy to install, but when you have loads that don't have inductive loads they are not very accurate.
An oven, traditional lamps,... will work fine, but electrical engines, TL lamps,... can have serious misreadings. In my case, a 60 cm TL lamp read 80 Watt using the clamps and the correct 25 Watt using e DIN kWh meter...
* correction:
"when you have loads that don't have inductive loads they are not very accurate."
was meant to be:
"when you have inductive loads they are not very accurate."
Indeed, this is my biggest problem with the clamps: seems that a lot of equipment these days has a crappy power factor, and flukso only becomes a relative measurement tool (before/after), absolute power is way off.
