ARAG Orion X 3" Magmeter Specifications & Installation

1. Technical & Metric Performance

• Measuring Range: 50 – 2500 L/min (approx. 13.2 – 660.4 GPM)

• Accuracy: +/- 1% of the measured value (within the 250 to 2500 L/min range)
  

• Maximum Pressure: 5 bar (approx. 72.5 PSI)
  

• Liquid Conductivity: Must be equal to or greater than 300 µS/cm
  

• Operating Temperature: 0°C to +60°C (32°F to +140°F)
  

2. Hydraulic Installation Logic

To ensure measurement accuracy and prevent turbulence, follow these placement rules:

• The 10x Rule: Install a straight pipe section both upstream and downstream of the meter. The length must be at least 10 times the inner diameter

  • For this 3" (75mm) meter, that is 750 mm (approx. 29.5 inches) of straight pipe on both sides

• Avoid Turbulence: Position the meter away from valves, bends, or bottlenecks

• Air Pocket Prevention: Always mount the meter in a position that favors the drainage of air

• Electrode Protection: Install the meter at least 3 cm (approx. 1.2 inches) away from metal masses

3. Electrical Connections & Pinouts

Frequency Port (Pulse Output):

• Pin 1: GND (Ground)

• Pin 2: +12 Vdc (Power)

• Pin 3: OUT (Square wave pulse signal)

4. Status LED Indicators

• Blue (Steady): Measurement active; liquid is flowing
• Green (Steady): Liquid is present but still (no flow)
• Violet (Steady): No liquid detected inside the meter
• White (Steady): Electrode cleaning in progress
• Red (Blinking): Error detected (refer to the pulse count for specific error codes)

5. Maintenance

• Post-Mix Flush: Always run clean water through the meter after each treatment session

• Electrode Cleaning: If the reading becomes unstable, use a special detergent to clean the pipe. Do not use metal or abrasive objects as they will damage the internal electrodes
