YF-S201 Water Flow Sensor Description
The external dimensions and indicated contents are consistent with the approved drawings and technical documents approved by the procedures. The installation is well coordinated and has a permanent flow direction sign.There are no obvious cracks, bumps, burrs and deformations on the surface.The water flow sensor is connected with the 5V power supply, and is directly measured by the oscilloscope through the 8L/min water flow. The water flow sensor can be artificially placed at the high level and tested with a multimeter voltage profile.Mainly used in water heaters, drinking fountains, water vending machines, campus credit card machines and other fields.

YF-S201 Water Flow Sensor Specification

 

Product appearance

Conform to the design

The external dimensions and indicated contents are consistent 
with the approved drawings and technical documents approved 
by the procedures. The installation is well coordinated and has 
a permanent flow direction sign.

There are no obvious cracks, bumps, burrs and deformations 
on the surface.

Distribution mechanical
strength

≥30N/ Arbitrary direction

Pull the wiring with a tension gauge,give the force1min/30N 
force, There must be no looseness in the Wiring.

Flow characteristics

F=(7.5*Q) error≤2%

2 to 12L/min water flow is applied at the inlet of the water flow 
sensor, and its output frequency characteristics should meet 
the standard requirements, formula F is Hz, Q is L/min.

High level

≥4.6V

The water flow sensor is connected with the 5V power supply, 
and is directly measured by the oscilloscope through the 8L/min 
water flow. The water flow sensor can be artificially placed at 
the high level and tested with a multimeter voltage profile.

Low level

≤0.5V

Electrical strength

1250V/min

In the case with any lead wire, the experimental voltage is 1250V, 
the setting current is 8mA, the experimental time is 1min, no 
breakdown, no flashover.

Insulation resistance

≥100MΩ

In 500V/ measuring insulation resistance.

Output duty cycle

50%± 10%

The flow sensor is connected to the 5V power source and is 
directly measured by an oscilloscope using the 8L/min curren.

low temperature

Flow characteristics,
output waveform should
meet the technical
requirements.

1) place the sample in -20℃ constant temperature box 2h, 
remove and stay 1h.
2) place the sample in -90℃ constant temperature box 2h, 
remove and stay 1h.
3) and then put the sample in the -20℃ constant temperature 
box 0.5h, put in -90℃ constant temperature box 0.5h., repeat 
third 5 cycle inspection.

high temperature

thermal shock

damp

The sample at the temperature of 40± 2℃, the relative humidity 
of 90% ~ 95%RH environment 48h, and then placed 2h at room 
temperature to confirm, re test the parameters, and parts without 
cracks, relaxation, deformation and other abnormalities.

Water pressure test

≤1.75Mpa

Stop the water flow sensor plug, applied pressure is less than 
or equal to 1.75MPa at the other end, the flow sensor without 
any leakage.
