They seem to be set up for international shipping, so just specify delivery to me.
I'll put my address in my profile.
OK- No response from the seller yet. BTW, when you have finished experimenting I would (probably) like to buy the pump off ypu.

OK : good enough for RUN-01 !!! Camera 1 ... Camera 2 ... ACTION!
... Completed, but with problems.
The level was still very bubbly for the first few 100 ml (Sock: failed Glove: seemed OK but not really)
The level against white was hard to read (try black background / add dye to water).
The webcam recording the manometer was only at 4 fps ... missed the maximum most frames.
I'll take a COUPLE of frame shots at 200ml 1000ml for PRELIMINARY results. (My choice of best frame)
Latecomers can still make bets until I post the results.
Having seen the pump in action, do you still feel that startup/shutdown error is a problem? If not then you could go with measuring how much water accumulates over 30 seconds or so as Alan Smith suggested a little while ago. Then splashing wouldn't be a factor. You could use the same analysis spreadsheet too. Think of it as a backup to your primary measurement plan.
WONDERING: why none of the most vociferous posters haven't made a bet ... Dewey, Mary Y, Rothwell, even TH Huxley, IH Fanboy ...
OK, I bet 38 L/h max, unless water is forced through the pump inlet by external pressure.
I'll be airport hopping for the next couple of days, on my way to the Arctic again.
Thanks, Alan, for doing the experiment. Hopefully I can see results before arriving at my destination.
I won't have internet for up to 2 months, so if I don't post for a long time, don't be surprised.
Cheers!

PRELIMINARY RESULT PENDING re-analysis of frames AND calibration at 1 bar (or 2 bar)
FLOW : 36.0871 l/hr at 0,15 bar
NOTE : for 24 pumps this is 0.65 of Penon's reported 32,000 Kg (aka Liters) / day
WARNING : These results do not PROVE or DISPROVE RossiSeztm or IH Claims
I think Paradigmnoia 38 l/hr is the winner of the quatloos.
Day's over ... have to run.
Future : If it's worth continuing, a digital scale is probably the way to go.
I'll get some food dye/black background for RUN02 ... maybe with a timed test, though bubble-elimination is a minor problem.
Penon actually reported 36,000 L/day for much of the time. Once measured, this figure was then arbitrarily reduced by 10% prior to calculating COP so as to produce a conservative estimate. That is where the 32,400 L/day figure comes from. The actual measured flow was 36,000 though
Oops ... didn't set video to Public .... can't find the button!
Single-handed, a timed test didn't work. Have to hit the start power AND clock simultaneously ... TWICE.
Black background didn't work either ... cant see the markings.
For now my method is best.
Next time up I'll use dye, and do a zero-height (0 bar) backpressure.
I chopped my 1/2 tubes, so I'll have to get another for a pressurized suction test.
I won't have internet for up to 2 months, so if I don't post for a long time, don't be surprised.
Cheers!

Elon Musk should solve that for you cerca 2020 with his massive number of low earth orbit global internet satellite launches about to commence.
Great first run Alan F.
Doesn't look great for Rossi's claim on the pump rate, albeit still need to calibrate the pump at (preferably) 2 bar back pressure, as you pointed out. Then there is the question about the "recirculator" and head pressure. It would also be courteous for someone to invite Rossi to comment on the setup and results.

We will have satellite Internet.... At $7 / Mb . So chittychatting won't be allowed.
More competition would be nice. Out normal satellite provider sold all their available bandwidth to some big company working in the region, so we are stuck with plan B for now.
You are the man Alan! Before conceding with my guess did you prime the pump before doing your run?
I always primed the pump, just by running it. Then the first 100ml cleared any remaining bubbles.
Before doing a full run I'll take a better shot of the manometer ... it was hitting between 5 and 6 psi (0.4 bar).
Alan. If you run the outlet tube to the bottom of your measuring cylinder splashing/bubbles would not be so problematic. This will generate a certain amount of 'siphon effect' which reproduces the fact that Rossi's system was a recirculation one, where water came back to the pump at the same (or very close to the same) pressure that it left it. At the moment you are pumping entirely uphill, notdownhill leg feeding the pump.

Ah, but then I have to subtract the volume of tube under water!
And I DO need to pump almost entirely uphill to get the maximum head.

Alan Fletcher : Thanks for the hard work!
Here a refresh for the less knowledgeables - from Ex 235-10:
Each BF unit has six identical small pumps to feed water into the reactor / boiler section of each unit. A closeup of the six pumps for a single reactor is shown below. Also shown is the nameplate for one of the pumps.
The BF's (Big frankies) were run 98% of the time according to AR. 65% of reported flow rate is a much better match with the doable Doral heat dissipation of max 4-500k Watt.
There is still a possiblilty that the two spare units just run a "cold" water flow...
Ah, but then I have to subtract the volume of tube under water!

I like my idea of weighing the water!
You can calibrate the scales with water in a measuring cylinder...
An output hose can be moved from weighed bucket to slops bucket or vice versa with a time resolution of < 1s
Not that it matters. Rossi would need an imaginary recirculation pump (which, if not imaginary, could easily be used to spoof the test recirculating hot water, so both ways it is problematic) to make the figures work.
