The ones I originally used were the plastic ones similar to the ones from Jaycar. They tend to last 2-3 years at most. They do have the advantage that the hall effect sensor can be replaced when lightning does its thing.
I have just replace one with one similar to

The original ones give 330 pulses per litre, the new one seems to give 420 pulses per litre. I haven't finished calibrating it yet.
I am hoping that the brass unit outlasts the plastic ones.
To use them, I use a counting pin and read the pin every 30 seconds and take the difference, divide by 330 (or 420), multiply by 2 = litres/minute
I have 4 flow sensors and have been using them since the first maximites.
I usually do the charting on a Windows PC and just let the 'mite remember what has happened.

Edit: I am using 3/4 inch units.
