I found the data sheet of my Hall effect 3 wires flow sensor: it produces a square wave, with frequency [Hz] = 0.5 x Q [liter/min]. As I know my typical irrigation flow is 100 liters/min (recommended range of my 1.5″ flow sensor is 10-150 l/min), the maximum frequency is 50 Hz = 50 pulses per second. Is this too much to handle for the OS ? Also I am irrigating in 15 minutes cycles, so total flow count is something like 50x60x15 = 45000, too high ? Thanks for checking into this.
Again I would gladly go with the 2-wires flow meters, but at 1″ thick they are 10″ long, I have no room in the pipes to install them.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
