Hi everyone
I'm working with this proyect: https://xively.com/feeds/1538624376, it's about water measuring at my home.
I use this sensor (Hall Effect):Liquid Flow Meter - Plastic 1/2 NPS Threaded : ID 828 : $9.95 : Adafruit Industries, Unique & fun DIY electronics and kits , but now I want to use a different sensor, I was researching about Ultrasonic flow sensor, Somebody here used that? or Somebody can give me an advice?
Please, Tell me How do you think about this sensor?
PD: Sorry for my English, I'm from Ecuador

There are specialist chips available for making ultrasonic flow meters. See (for example) Home | Precision Measurement Technologies.

Did you ever do anything for this?
Hi guys 
,
Has somebody developed any non contact flowmeter with Arduino? Something like:
Do you consider a good method to detect leaks?
