waterflow sensor

[12345caravan]

For anyone getting tired of the misreadings from the optical sensors with their watermeter,
I can recommend this flow sensor.

I use it in combination with my piface board, it's working excellent, no more spikes/drops etc...
Easy install too.

Nice, but looks like you need to install it inline of the waterpipe...
And which manufacturer/type/price?

Just build one based on the tcrt5000 for my watermeter to hookup on GPIO directly and place it above the reflective mark on my watermeter.

Type ?
Price ?
Thnx

looks like a Uxcell G1/2.... 1.5~30lt/min
around 10€... a bit less maybe
available also via amazon by sourcingmap (but higher price)

I think its this one:

uh... just a question....
a sensor like this shall be used just to get the water flow... or can it be used for couting m2 also?

I'm evaluating 2 different scenarios for it:
- Heating system (for which I would need just the flow control) to understand if the system is running and how
- Water consumption (for which I would need to count the m2 also), but I do not have the counter in my flat

Thinking to connect it to domoticz... what would be the best solution? MySensor? direct GPIO? or other ways?
and how would it be handled?

thanks

Only counting liters no flow control/valve.
Bought mine through aliexpress.
You can connect it anyway you want, for me piface is the easiest way for pulse counting,
and you can use the output on the piface for an extra electric valve.

Thank you...
My intention is to connetct it to a raspberry and update the domoticz PI via Api.... so I will create a virtual counter and update it...
at least the flow control will be made by checking the last update value (so I know the centralizer boiler and pump are on )

or at leat install a domoticz server and use the GPIO hardware... create a virtual counter and have the 'master' use the remote device....
could it work this way?
thanks

P.S.
am I correct if I sentence that for doing that... in that way mySensor would be best and probably cheapest way?

could you post the script you use for this water flow sensor?
I bought the sensor too, but is has 596 pulses every liter, yours too?
