5 Common Misconceptions About Radar Level Gauge Selection and Use

Misconception 1: The higher the frequency, the better

Problem: Blindly pursuing high-frequency radar

80 GHz performs well in small vessels

Howver, 6 GHz is more cost-effective for large tanks

26 GHz is the best choice for most operating conditions

Solution:

Select frequency based on tank size

<5 meters: 80 GHz

5-15 meters: 26 GHz

15 meters: 6 GHz

Misconception 2: Ignoring media characteristics

Problem: Ignoring the effect of dielectric constant

Low dielectric media (ε < 1.4) result in weak signals

Highly viscous media tend to adhere to the antenna

Corrosive media can damage equipment

Solution:

Confirm media characteristics before measurement

Use special materials for corrosive media

Select clean models for viscous media

Misconception 3: Random installation location

Problem: Improper installation location leads to measurement errors

Close to the feed Data fluctuations

Tilted installation causes errors

Insufficient blind zone causes measurement failure

Correct installation:

Distance from tank wall ≥ 30 cm

Vertical installation with an inclination < 3°

Allow a 0.3-0.5 meter blind zone

Mistake 4: Ignoring environmental factors

Problem: Failing to consider the effects of temperature and pressure

High temperature damages electronic components

Pressure changes affect accuracy

Vibration causes equipment to loosen

Protective measures:

Select wide-temperature equipment

Confirm pressure rating compatibility

Install anti-vibration mounts

Mistake 5: Neglecting routine maintenance

Problem: Never maintaining after installation

Antenna contamination causes signal attenuation

Seal aging and water ingress

Parameter drift causes reduced accuracy

Maintenance plan:

Monthly cleaning of the antenna

Quarterly seal inspection

Annual professional calibration

Professional advice:

Avoiding these common mistakes can extend the life of your radar level meter by 50% and improve measurement accuracy by 30%. Consulting with a professional technician is recommended before selecting and installing a radar level meter.
