Lead the way:
1 red IN then positive
2 yellow OUT signal output line
3 black GND then negative
Frequency: F = 5 * Q (L / Min) -3 error: ± 2% voltage: 3.5-24VDC, current can not exceed 10mA, finished a liter of water stream output 300 pulses
That constant frequency calculation = 5 * Unit Flow (L / min) * Time (seconds) -3 (Revised - can be reduced to be diminished)
Flow range: 1-30L / min
