YF-S402 G1 / 4 DN8 0.3-6L / Min DC4.5V water flow sensor
Features:
1, the product looks lightweight and flexible, small size, easy installation.
2, lined with stainless steel impeller shaft, multi-point focus, never wear and extend the service life.
3, the seal structure of the force will not leak.
4, Hall element imported water-proof design, waterproof, never aging.
5, all raw materials are in line with ROHS testing standards
First, the introduction:
Water flow sensor from the plastic body, rotor assembly flow and Hall sensor.
It is installed at the inlet of the water heater to detect water flow through the rotor assembly,
A magnetic rotor and flow rate to adapt to changes in the corresponding Hall sensor output pulse
The signal is fed back to the controller, which depends on the size of the water traffic control.
Be careful:
Non-violent shocks and chemical attacks.
Do not throw or crash.
Put the arrow product in water.
Medium temperature should not exceed 120 degrees
Second, lead the way:
Then the positive red IN IN
Yellow OUT signal output line
Black GND Negative polarity
Frequency: F = 73 * Q (L / Min) Error: ± 2%
Voltage: 3.5-24VDC, the current can not exceed 10mA, 4380 output pulse after a liter of water flow
Frequency calculation unit 73 * = constant flow rate (L / min) * time (second)
Flow range: 0.5-5L / min
