What are the liquid connections? The manufacturers say its a female thread but they have some sort of nipple sticking out in the photos.
It works really well. I get a flow reading of about 3-5 liters/hour at idle.

I haven't hat any issues with fuel restriction at WOT.

I would not consider the connection to be female. It's like the connection on my water separator. It's a litle metal nipple/nose/tube that goes inside the fuel hose.

Send me a PM with your address and I will send you one.

Thanks for the offer, but i have already ordered one yesterday!
He accepted my best offer of $24

He said they have been used on kindey dialysis machines measuring saline and bicarbonate solutions.

Got my microstream flowmeter today.
is yours 1 pulse per 450 micro litres? I make that 2222.22 pules per litre. Do you agree?
Any update on the android app?

Could be OK. What number does it say on the sensor? Go with that number. I found it to be accurate.

I have made another version that calculates mean consumtion instead of instant, but it's in a early stage. Nothing to make public yet.

Finally a free weekend without rain so i thought i would get this sorted out.

I ran some tests on the Micro Stream flow meter using the calibration script.

1000 grams of Water at 14C (1 litre):
Test Count Time
1 2197 2m 08 sec
2 2198 2m 10 sec
3 2197 2m 13 sec
4 2194 2m 09 sec
5 2196 2m 13 sec

737 grams of Petrol at 15C (1 litre)
Test Count
1 2168
2 2163
3 2166
4 2161
5 2160

I was shocked to see how close together the results are. This is one accurate sensor!

I was surprised to see how freely the liquid passed through the sensor too. No fuel starvation issues here.

I squeezed the hose down with a clamp to a slow drip of about 1 drip/sec and the sensor still counted. Very nice.

That's why I bought 6
