Radar Level Transmitter Installation & Maintenance Guide – Ensure Long-Term Accuracy

Proper installation and maintenance are critical for radar level transmitters to deliver reliable performance. This guide covers best practices from setup to troubleshooting.

Installation Steps

1. Site Selection

• Avoid obstacles (e.g., agitators, heating coils) inside tanks to ensure clear signal paths.

• If mounted at an angle, align the antenna axis perpendicular to the liquid surface.

2. Mounting

• Seal flanges/threads tightly to prevent leaks (critical in high-pressure/corrosive environments).

• Ensure structural stability for top-mounted devices to minimize vibration errors.

3. Parameter Configuration

• Input dielectric constant (affects signal reflection).

• Set blind zones based on measuring range (typically 0.3~1m near the antenna).

Maintenance & Troubleshooting

• Routine Checks:
  ✅ Clean the antenna surface to remove dust or condensation.
  ✅ Inspect cable connectors for water resistance.

• Common Issues:
  No Signal: Verify power supply and check for obstructions.
  Data Fluctuation: Address foam/vapor interference or adjust filtering settings.

Recommendation: Calibrate every 6 months; shorten intervals in extreme conditions.
