Appearance: clear product identification, accurate compliance
Water pressure resistance:> 1.75MPa
Operating voltage range: DC5 ~ 24V
Insulation resistance:> 100M?
Accuracy: ( in 1 ~ 60L MIN ) 3%
Flow pulse characteristics: (4.8 * Q) Q is L / Min,
1L in Example 1 is 4.8 * 288 * 60 = the number of pulses that flow through an output liter, i.e., an output of 288 liters of pulses 60 is the time (in seconds)
Low temperature test: 72h after standing at a temperature of -20 C, and for 1h at room temperature, the accuracy of the first measured value 5%
High temperature test: Place after 72h at a temperature of 85 C, place 1h at room temperature, 3% accuracy in the measurement of the first
Wiring: Red + ;Black -; yellow pulse signal output.
