Title: Expert Guide: Best Practices for Radar Level Transmitter Installation And Maintenance

Introduction
Proper installation and regular maintenance are crucial for ensuring long-term stable operation of radar level transmitters. This article provides detailed installation guidance and maintenance recommendations to help you maximize equipment performance and extend service life.

1. Pre-Installation Preparation

• Site Survey: Confirm medium characteristics, process temperature/pressure, tank dimensions and material

• Antenna Selection: Choose horn, rod, or parabolic antenna based on dielectric constant

• Location Planning: Avoid interference sources such as inlets, agitators, and heating coils

2. Detailed Installation Steps
2.1 Flange Installation

• Use matching gaskets to ensure sealing

• Tighten bolts uniformly in diagonal sequence

• Check flatness after installation, deviation should be <0.5°

2.2 Thread Installation

• Use sealant tape or thread sealant

• Avoid overtightening causing thread damage

• Recommended torque: ≤60N·m for 316L stainless steel flange

2.3 Precautions

• Maintain antenna perpendicular to medium surface

• Minimum distance from tank wall: ≥100mm

• Maintain ≥500mm spacing when installing multiple transmitters

3. Commissioning and Parameter Setting
3.1 Empty Tank Calibration

• Perform empty tank learning to establish reference baseline

• Set correct dielectric constant and range parameters

3.2 Echo Curve Analysis

• Identify true echoes and false echoes

• Use echo mapping function to mask fixed interferers

4. Preventive Maintenance Schedule
Monthly Checks:

• Inspect antenna surface cleanliness

• Verify output signal stability

• Record deviation between measured and actual values

Quarterly Maintenance:

• Clean antenna surface deposits

• Check cable connector sealing

• Calibrate zero and span

Annual Maintenance:

• Comprehensive cleaning and calibration

• Check seal aging condition

• Update firmware and backup parameters

5. Common Troubleshooting

Conclusion
Following correct installation and maintenance procedures ensures radar level transmitters maintain optimal measurement performance. We recommend establishing detailed equipment records and documenting all maintenance data to build a foundation for predictive maintenance.
