Product Description
Product Description
The Atlas Ultrasonic Flow Meter (Model LFM-0.5) is a compact, high-precision water flow measurement device designed for seamless integration with Atlas UV water treatment systems. Using advanced ultrasonic technology, it delivers accurate, wear-free, and maintenance-light performance—ideal for residential, commercial, and light industrial water treatment applications.
Key Features
⚙️ Advanced Ultrasonic Technology
-
No moving parts – zero mechanical wear or fatigue.
-
Accurate and reliable water flow measurement using ultrasonic sound waves.
🌿 Energy Efficiency
-
Works with Atlas UV systems to automatically activate Energy Saver Mode, dimming the UV lamp when no flow is detected.
-
Reduces energy consumption and prevents overheating during idle periods.
💧 Performance & Compatibility
-
Flow range: 0.1–20 GPM (0.4–75 L/min)
-
Accuracy: ±5% relative error within flow range
-
Pipe diameter: ½ inch
-
Connection: ½” NPT
-
Power supply: +5VDC, 100mA max
-
Pressure drop: Minimal across operating flow range
-
Compatible with Atlas UV Systems using Firmware v2.13 or higher.
🧠 Smart Operation
-
Real-time flow rate display on the controller screen (GPM, LPM, or m³/h).
-
LED indicators for operational status:
-
Solid green: Active, no flow
-
Flashing green: Active, flow detected
-
Solid red: Fault detected
-
Flashing red: Over-range flow condition
-
