Water pressure resistance: 1.75MPa
Output pulse high level: >DC 4.7V (input voltage DC 5V)
Flow pulse characteristics:
1/2" F=[18*Q-3], That is 1077 pulses per liter of water;
3/4" F=[15*Q-3], That is 897 pulses per liter of water;
1" F=[10*Q-5], That is 595 pulses per liter of water;
1-1/4" F=[1.8*Q], That is 108 pulses per liter of water;
1-1/2" F=[0.45*Q], That is 27 pulses per liter of water;
2" F=[0.2*Q], That is 12 pulses per liter of water.
(F is frequency, Q is L/min) Error±5%
Tightness: Close each hole, add 1.75Mpa water pressure test for 1 minute without leakage and deformation.
