Description
The YF-B2 water flow sensor is small in size and easy to install. The sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor. It is installed at the water inlet end of the gas boiler to detect the water flow.
Technical Specifications:
Working voltage range: DC 5～18V
Minimum rated working voltage: DC 5V

Storage humidity: 25% ～ 95% RH
Liquid temperature max: 120°C
Connecting wiring:
JST connector
Red wire: IN Yellow wire: OUT Black wire: GND
Output specifications:
Output pulse high level: > DC 4.5V (input voltage DC 5V)
Output pulse low level: < DC 0.5V (input voltage DC 5V)
Fine output (Flow -- pulse output): 1～ 25L/min ±3 %
Output pulse duty cycle: 50±10%
Output rise time: 0.04 μS
Output fall time: 0.18 μS
Flow - pulse characteristics: Horizontal test pulse frequency (Hz)=[ 11* Q]± 5 % (horizontal test) (Q is flow rate L/min)
Environmental resistance:
Impact resistance: The product is well packaged and shows no abnormality when freely dropped from a height of 50cm in the X, Y, and Z directions to the concrete surface. Accuracy varies within 5%.
Insulation resistance: The insulation resistance between the Hall sensor and the copper valve body is more than 100 MΩ. (DC 500V)
Heat resistance: in an environment of 80±3℃ for 48 hours, return to normal temperature for 1-2 hours without abnormality, and the parts have no cracks, relaxation, expansion, deformation and other phenomena, and the accuracy changes within 10%.
Cold resistance: in -20±3℃ environment for 48 hours, return to normal temperature for 1-2 hours without abnormality, and the parts have no cracks, relaxation, expansion, deformation and other phenomena, and the accuracy changes
