Atlas Ultrasonic Flow Meter 1/2 in ports

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

Technical Specifications

Installation & Maintenance

• Must be installed on the inlet side of the UV chamber.

• Install horizontally for best accuracy; vertical installation is possible if the pipe remains full.

• Requires at least 10× the pipe diameter in straight inlet piping before the flowmeter.

• Includes NPT adapters, union nuts, and rubber washers for easy setup.

• Annual cleaning recommended with a descaling solution to maintain precision.

• No recalibration required.
