Great price and works good
We never have any idea when our RO membrane should be changed. Our water is of fairly high quality before the RO so it’s hard to tell when the RO filter is letting stuff through. Now we can measure when to change. Attaching this to a counter (raspberry pi or others) can be a bit of a steep Learning curve but I found it a fun technical challenge.Once calibration is done this is meter is quite accurate. Built in push connections make installation as easy as LEGO.

Works Great.
I am giving this five starts because it has worked great so far after some initial testing. I will be looking forward to using it to automate the watering of my tomato plants in the future.

Just works.
Simple to use. Just set up a rising edge interrupt to count the pulses and calculate flow volume and rate.

DAC or voltage divider required
No instructions or schematics

works
Seems to work as advertised though the pulse rate seems a little inconsistent
