1, the lowest rated working voltage: DC4.5 5V-24V
2, the maximum working current: 15 mA (DC 5V)
3, working voltage range: DC 5 ~ 18 V
4, load capacity: ≤ 10 mA (DC 5V)
5, the use temperature range: ≤ 80 ° C
6, the use of humidity range: 35% ~ 90% RH (no frosting state)
7, allow pressure: water pressure below 1.75Mpa
8, storage temperature: -25 ~ 80 ° C
9, storage humidity: 25% ~ 95% RH
Precautions for use:
Severe impact and chemical attack are strictly prohibited.
It is strictly forbidden to throw or collide.

Lead line mode:
1 red IN connected to the positive pole
2 yellow OUT signal output line
3 black GND connected to the negative
Frequency: F=7.5*Q(L/Min) Error: ±2%
At a flow rate of 1 L/min, 7.5 * 1 * 60 is equal to the number of pulses flowing through 1 liter of water. Voltage: 3.5-24 VDC, the current cannot exceed 10 mA, and 450 pulses are output after one liter of water.
That is, frequency calculation = constant 7.5 * unit flow rate (L / min) * time (seconds)
Flow range: 1-30L/min
