Product Description
Product Description
The Atlas Ultrasonic Flow Meter ¾" (Model LFM-0.75) provides precise, contact-free flow measurement using ultrasonic wave technology. Engineered for integration with Atlas UV water purification systems, it ensures accurate, consistent flow monitoring while helping the UV system reduce energy consumption during no-flow periods.
With no moving parts and minimal maintenance, this sensor is ideal for residential, commercial, and light industrial installations where reliability, energy efficiency, and precision are essential.
Key Features
⚙️ Ultrasonic Flow Measurement
-
Non-invasive flow detection – no moving parts or wear.
-
Measures flow using high-frequency sound signals within the pipe.
-
Provides long-term reliability and accuracy without recalibration.
🌿 Energy-Saving Operation
-
Enables the UV system’s Energy Saver Mode when no flow is detected.
-
Reduces power consumption and prevents overheating of standing water.
-
Instantly restores full UV lamp power when water flow resumes.
💧 Performance Highlights
-
Flow range: 0.1 – 30 GPM (0.4 – 114 L/min)
-
Accuracy: ±5% relative error
-
Pipe size: ¾ inch
-
Connection type: ¾” NPT
-
Input voltage: +5 V DC (100 mA max)
-
Inlet pipe length: Minimum 7.5 inches straight pipe required
-
Pressure drop: Low, across all rated flow ranges
-
Firmware compatibility: Works with Atlas UV firmware v2.13 and higher
💡 Smart LED Indicators
| LED State | Status |
|---|---|
| Solid Green | Flowmeter active, no flow detected |
| Flashing Green | Flowmeter active, flow detected |
| Solid Red | Flowmeter fault detected (dimming disabled) |
| Flashing Red | Flow rate above rated maximum |
Technical Specifications
| Parameter | LFM-0.75 (¾") Specification |
|---|---|
| Flow Range | 0.1 – 30 GPM |
| Accuracy | ±5% within flow range |
| Input Voltage | +5 V DC (max 100 mA) |
| Pipe Diameter | ¾ inch |
| Adaptors | ¾” NPT |
| Inlet Piping Requirement | 7.5 inches (10 × pipe diameter) |
| Orientation | Horizontal (recommended); vertical if pipe remains full |
| Connection Port | IEP (Infinite Expandability Port) |
| Pressure Drop | Minimal |
| Power Mode Integration | Supports automatic UV system dimming during no-flow |
| Calibration | Factory calibrated – no annual recalibration needed |
Installation Guidance
-
Install on the inlet side of the UV chamber only.
-
Mount horizontally with the label and LED facing sideways toward the user.(as seen in images)
-
Ensure the arrow direction matches the flow direction on the UV inlet.
-
Provide 7.5 inches of straight pipe before the Flow Meter.
-
Connect to the IEP port on the controller or compatible module.
-
Power using the supplied 5 V DC wall adaptor (max 100 mA).
-
Avoid installing near electric motors or high-voltage lines to prevent interference.
Operation & Display
When connected, the UV controller displays:
-
Flow rate (in GPM, LPM or m³/h)
-
Lamp status (Full Power or Energy Saver Mode)
-
Flowmeter error messages, if applicable
The system automatically dims the UV lamp after one hour of no flow and instantly resumes full operation once flow is detected.
Maintenance & Cleaning
-
Clean annually to prevent mineral scaling and maintain accuracy.
-
Submerge the flow pipe in a mild descaling solution (e.g. CLR® or LIME-A-WAY®).
-
Rinse thoroughly with clean water before reinstalling.
-
No calibration required post-cleaning.
Applications
✅ UV water purification systems
✅ Residential and light commercial flow monitoring
✅ Process control in water treatment plants
✅ Energy-efficient disinfection systems
Product Benefits
-
Non-contact ultrasonic accuracy
-
Zero moving parts – minimal wear and maintenance
-
Intelligent energy-saving control
-
Easy plug-and-play installation
-
Long lifespan and dependable performance
