Product Description:
YJJ AFD2125W00 Water Flow Sensor for Gas-Fired Boiler & Instant Hot-Water-Heater Flow-Control
Features:
I. Basic Information
Model: AFD2 series (AFD2106/2110/2120/2125)
Brand: Guangzhou Aosair Electronics
Principle: Von Karman vortex street (vortex street type), measuring flow by detecting the frequency of fluid vortices, without moving parts, resistant to impurities, low pressure loss
Medium: Clear water, pure water, water heating medium (can add antifreeze)
II. Core Technical Parameters
1. Range selection (mainstream 4 types)
AFD2106: 0.5 - 10 L/min (DN10)
AFD2110: 1.8 - 32 L/min (DN15)
AFD2120: 5.0 - 85 L/min (DN20)
AFD2125: 9.0 - 150 L/min (DN25)
2. Accuracy
50% of the range or below: ±1% FS
50% of the range or above: ±2% reading, repeatability < 2%
3. Electrical and Output
Power supply: 11.4 - 26 VDC (wide voltage)
Output: 4 - 20 mA / 0 - 10 V analog signal, can be directly connected to PLC / microcontroller
Pressure resistance: 1.0 MPa (10 bar)
4. Environmental Conditions
Medium temperature: Clear water 0 - 90℃; with antifreeze - 20 - 90℃
Environmental temperature: -30 - +65℃
Humidity: 10% - 95% RH (no condensation)
5. Materials & Structure
Main body: PPS + GF (glass fiber reinforced plastic), resistant to water and corrosion
Interface: external threads (G1/2, G3/4, G1), easy installation
Features: no mechanical wear, anti-scaling, low pressure loss, long-term zero drift
III. Main Applications
1. Household and HVAC (core application)
Gas water heaters, wall-mounted boilers, heat pump water heaters: inlet water flow monitoring, start / constant temperature control
Central air conditioners, floor heating, heat recovery systems: closed-loop monitoring of water circulation flow, preventing evaporator icing, compressor failure
2. Medical equipment
