Recommendation
SeaDeal selects radar frequency by tank height, nozzle size, beam angle, medium condition, target accuracy and budget.
Comparison table
| Criteria | Recommended option | Alternative option |
|---|---|---|
| Beam angle | 80 GHz has a narrower beam. | 26 GHz has a wider beam. |
| Nozzle fit | 80 GHz is often easier for narrow nozzle retrofits. | 26 GHz needs more mounting clearance. |
| Budget | 80 GHz usually costs more but reduces installation risk. | 26 GHz can be lower cost for simple tanks. |
Application scenarios
Both radar frequencies can work, but wrong beam angle or nozzle fit can create installation problems and unstable readings.
Comparison context: Both radar frequencies can work, but wrong beam angle or nozzle fit can create installation problems and unstable readings.

Selection guide
- Measure tank height and nozzle diameter.
- Check internal obstructions and mounting angle.
- Use 80 GHz when the beam must avoid tank walls or agitators.
- Use 26 GHz only when installation clearance and medium conditions are simple.

Frequently asked questions
Is 80 GHz radar level meter better than 26 GHz?
80 GHz is often better for narrow beam and retrofit installation. 26 GHz can still be suitable for simple tanks with enough nozzle clearance.
Which radar frequency should I choose for a chemical tank?
For many chemical tanks, 80 GHz is preferred because narrow beam and non-contact measurement help with nozzle and vapor conditions.
