Product Description:
YJJ AFD5004R10 Vortex Liquid Flow Sensor of 0.5 - 4 L/min for Industrial Equipment Cooling
Features:
I. Key Parameters (Official Specifications)
Model: AFD5004R10 (ASAIR AFD5 series)
Measurement Principle: Von Karman Vortex (Vortex)
Flow Range: 0.5 - 4 L/min (for liquids)
Accuracy: < ±3.0% F.S; Repeatability < 2.0%
Interface Specifications: G3/8 (DN10), Union Thread
Output Signal: RS485 (Modbus RTU), R10 = RS485 + Display
Power Supply Voltage: 18 - 28 VDC (Typical 24V)
Medium: Water, Oil, Low-viscosity Clean Liquid
Contact Materials: PPS (Shell) + SUS304 (Flow Channel), Corrosion Resistant
Working Pressure: 10 bar (Maximum 16 bar)
Working Temperature: -20℃ - +60℃
Pressure Loss: Low Pressure Loss, Energy-saving
Protection Grade: IP65
Size / Weight: Approximately 80 × 45 × 35 mm; Approximately 350g
II. Working Principle
Fluid flows through the internal diffuser plate → generates periodic vortices (Von Karman Vortex) → the built-in sensor detects the vortex frequency → the frequency is proportional to the flow rate → the chip converts it into a flow value → local display + RS485 upload.
Core Advantages: No moving parts, no wear, no drift, long lifespan, corrosion-resistant.
