Product Features:
1, the item appearance lightweight adaptable, little size, easy to install.
2, trimmed with tempered steel impeller shaft, constantly wearable.
3, seal with the structure under the power never spill.
4, the Hall component imported from Germany, and with a preparing bundle, to avert water, never maturing.
5, every single crude material are in accordance with ROHS testing guidelines
I. Introduction:
Water Flow sensor is basically made of a plastic body, the flow of the rotor gathering and a Hall sensor. Which is mounted in the channel end of the warmer, for identifying the flow of water when the water moves through the rotor gathering, As the speed of revolution of the rotor and the attractive flow change, a relating Hall sensor output beat Signal, the criticism to the controller, the controller decides the measure of the water stream, direct.
Caution:
Third, lead the way:
1 red IN then positive
OUT signal output line 2 Yellow
3 Black GND then negative
Frequency: F = 73 * Q (L / Min) -3 error: ± 2% voltage: 3.5-24VDC, current can not exceed 10mA, finished a liter of water flow pulse output 4380
That constant frequency calculation = 73 * Unit Flow (L / min) * Time (sec) -3
Flow range :0.5-3L / min
Four, the technical parameters
