Product Description

YF-S402 G1/4 DN8 0.3-6L/Min DC4.5V Water Flow Sensor

Product Features:

1, the product appearance of lightweight flexible, small size, easy to install.

2, the interior lined with stainless steel impeller shaft, multi-point focus, never wear and prolong life.

3, seal with the structure under the force never leaks.

4, the Hall element imported with water isolation design to prevent water, never aging.

5, all raw materials are in line with ROHS testing standards

I. Introduction:

Water flow sensor consists of a plastic body, the flow of the rotor assembly and a Hall sensor.
It is installed in the water heater inlet end for detecting the flow of water when the water flow through the rotor assembly,
A magnetic rotor and the flow speed is adapted to change, the Hall sensor output corresponding pulse
Signal feedback to the controller, the controller is determined by the size of the water traffic regulation.
Caution:
Non-violent shocks and chemical erosion.
Prohibited throw or collision.
Press the arrow products put into the water.
Medium temperature should not exceed 120 degrees
Second, lead the way:
Then positive red IN
Huang OUT signal output line
Black GND to negative

Frequency: F = 73 * Q (L / Min) error: ± 2%

Voltage: 3.5-24VDC, current can not exceed 10mA, a liter of water flow after 4380 output pulse

That frequency calculation unit 73 * = constant flow rate (L / min) * Time (seconds)

Flow range: 0.5-5L / min

Third, the technical parameters
