Hi Ray,
following your post, I wired up a cheap hal-sensor driven flowmeter with ease! Working so far, providing readings. But specs are 270 pulses per liter, which is a 0.0037 liter per pulse. Any chance you can mod upcoming release to support others than full integer in liter/pulse setup? (or pleae direct me to how modify myself). Those Flowmeters are cheap and I have demand for various installs here.
Greetings,
Gregor
