Ah - Mixergy - ok - I was looking for a setup that didn’t involve it’s own operating system…
Heating bod should follow my gibberish. Air drops out at the top and where things slow down. Put the expansion vessel higher than it is. Put two tees into the vertical pipe that rises to it. The lower tee feeds the meter. The upper tee bleeds off the air into the air admittance valve. You need to feed the system with water from below the point the air has been bled out.
They look interesting - Altecnic even says for heatMeters @glyn.hudson@TrystanLea - for your kit? It does say They are the ideal valve for isolating the temperature probe of heat meters So isolating the probe and the meter.
However, I’m not sure I want the actual probe in the water (that is what that looks like)
I still look at that and think it is a fair % of the free diameter. When I re-pipe my tank I’ll probably get tee’s fitted with enough depth to set the probe just outside the water flow, but these are really interesting.
Interesting call. Looking at Sharky 775 heat meter questions - #23 by Zarch, how about a simple up and over loop of pipe. Halfway along a tee, up to a second tee off to to left for the expansion vessel (lifted up) and straight up for the AA valve (and give it a bit of pipe as well).
Probably improves the flow (not turning on 2 tees). Should still allow the air to rise.
Personally, I’d do a radius bend, but Plumbers seem to be adverse to bending pipe these days.
The green washers are the fibre washers to sit between the flow sensor and the flat face union couplings to seal them.
Try Alex Thornton at UK Metering for Kamstrup spares; they usually have good stock. Else if you don’t care for the parts being new I’ve probably got a bunch of these direct immersion probes in t he e might be useful one day corner that you can have for cost of post. PT500 type?
Possibly, but since my meter is a Sontex even if there were air pockets in there the reading would be effected. Have you tried increasing your system pressure up to 2bar? This fixed the same issue for:
I will keep and eye on it. I’m now also logging the raw power/flow feeds from the sharky before I curtail them with ‘max’ limits. I want to see what values the interface throws out in times of the sharky erroring and wonder if the interface can handle this better, as not to throw crazy wild data into the input and subsequent feed.
I’d still like to get it resolved properly though, ie heat meter placement.
And if a rejig/re-ordering of the expansion/AA and heat meter is the answer, then I’d do it as I want this to work flawlessly for the long haul.
And worst case, i’ve got a Sontex sat here in a box.
Quick hack: Bleed any air from the pipe up to the expansion vessel by cracking the union nut holding the pipe to the expansion vessel to release any air there and try again. May need to repeat a few times to purge all air from system.
