Product description

Model: YF-S201
Color: Black 
Material: PVC

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. Application: Mainly used for water heater, water machine, card machine, various types of filling equipment and water control device

Features:
Light weight, small size, easy to install.
Inlaid with stainless steel impeller shaft, durable wearable.
Seal Ring with the upper and lower force structure never leaks.

Precautions:
Non-violent shock, and chemical erosion.
Non-throwing or hitting.

Mounted vertically, should not exceed 5 degrees inclination.
Temperature of Medium should not exceed 120'C
Cord Connection:
Red: Positive(+);Yellow: Signal output;Black: Negative(-)

Dimensions: 2.44 in x 1.42 in x 1.34 in (6.2 cm x 3.6 cm x 3.4 cm)
Weight: 1.76 oz (50 g)

Frequency:¬†F=7.5*Q(L/Min)¬†;¬†Error:¬†¬Ī2%
Taking a example of the flow rate of 1L/min, that is, 7.5 * 1 * 60 is equal to the pulses output by 1 liter of water.
Voltage: 3.5-24VDC, current can not exceed 10mA, output 450 pulses after flowing one liter of water.
That is, frequency calculation = constant 7.5 * unit flow (L/min) * time (seconds)
Flow range: 1-30L/min

Packing List:
1 x Water flow sensor
