Hi everyone,
I'm new here, so a short introduction might be welcome. I'm from Austria, live near Vienna and am passionate about collecting and graphing all kinds of data I can get my hands on.
I am about to order a flukso v2b and would be happy if someone could answer me a few questions beforehand.
I plan a setup like this:
- main: 3 phase S0 pulse meter for total electricity consumption metering
- detail: up to 4 selected points for detailed measurement of parts of my house using a combination of clamps and single-phase S0 meters
Question 1: That should work like I imagine, right?
Question 2: Is there a difference in the results between using an S0 meter and a clamp?
Question 3: The B+G E-Tech DRT428DC-V3 S0 meter seems an inexpensive product to me and has 2000imp/kWh with a pulse length of 30ms.
I have already read the posts regarding the imps/kWh and think the 2000 should work fine (I like it being more granular than a 1000imp/kWh one).
But what about the pulse length, I haven't found any info on that. Is 30ms a supported value, or to I need a 90ms meter?
Thank you four your feedback!
Florian

i dont know how you imagine but yes with the flukso allowing (1 analog (ct clamp) and 4 pulse ports) or (3 analog and 2 pulse) that gives you 5 measuring devices available.

there can be a difference and that varies with lots of different circumstances.
about halfway down the page it explains that theres is reading 2.3KWh out

with my current setup not using a flukso i use a current cost with CT clamps and pvbean counter to upload to pvoutput.
I had to change my power correction factor to .96 to get it to be close to the sam weekly figure as the mains power meter.
in short pulse gives a more exact reading. just be aware your pulse meter should be a direct connect not a transformer connected (CT)

unsure on pulse length a more knowledgeable user may be able to help you but i dont think it will matter.
Q1: Yes.
Q2: via S0 pulses per kWh are registered; current clamps read current, thus "interpolate" the power usage by multiplying a fixed voltage (the Fluksometer does not measure mains voltage) with a measured current; by the principle of current measurement you may get issues with bad power factors (never use a clamp with a solar inverter - see lots of posts in this forum - g**gle
site:flukso.net <your search term>) - this means: clamp measurements are very accurate on resistive loads and hardly compete with a dedicated power meter - but they deliver valuable indication. Don't expect accounting accuracy...Q3: Yes; I also use a 20Eur 2000imp/kWh device (on my solar inverter); the Fluksometer registers pulses on input change, thus is independent on pulse length (30ms are "eternal")...
On last comment: You won't get a similar device for the same amount of money (except you build and more importantly program it on your own), even though some chaps in this forum claim differently... (I am also just a user)
Thank you, to both of you, for the confirmation.
Order has been placed, can't wait to have it in my hands :-)
