Radar Level Transmitters: Smart Solutions for Industrial Measurement

1. What Is a Radar Level Transmitter?

A radar level transmitter is a non-contact instrument that uses microwave signals to measure liquid levels. It works by:

• Emitting high-frequency waves from an antenna

• Detecting reflections from the liquid surface

• Calculating distance based on the time-of-flight (ToF) principle

2. Key Benefits

✅ High Accuracy – Measures within ±1mm error
✅ Reliable in Harsh Conditions – Unaffected by temperature, dust, or foam
✅ Low Maintenance – No moving parts, long lifespan (8-10 years)
✅ Versatile – Works with water, oils, chemicals, and more

3. Common Applications

• Oil & Gas – Crude oil, diesel, acid storage

• Food & Beverage – Milk, juice, hygienic processing

• Wastewater Treatment – Sludge, foam, and corrosive liquids

4. How to Choose the Right One?

Frequency → 26GHz for general liquids, 80GHz for sticky/foamy media
Range → Short-range (0-5m) use 80GHz, long-range (30m+) use 6GHz
Environment → Explosive areas require ATEX/IECEx certification

5. Installation Tips

⚠️ Avoid mounting near inlet pipes or agitators
⚠️ Keep the antenna clean for best performance
⚠️ Ensure proper grounding to prevent interference

6. Troubleshooting Guide

Weak Signal? → Clean the antenna
Fluctuating Readings? → Check for foam/turbulence
No Signal? → Verify power & wiring

Pro Tip: Wipe the antenna with a soft cloth monthly to extend its life.
