When it comes to non-contact level measurement, both Ultrasonic and Radar are two of the most common types, while radar is divided according to a different frequency, namely: 26GHz, 80GHz, and 120GHz. Those devices applied similar measuring principles, installation(from top to end), and for dealing with similar industrial applications. Each technology has varying degrees of success in different applications.

Ultrasonic level instrumentations are cost-effective devices, which are suitable for some simple applications, but they’re not as reliable or accurate in changing or difficult environments. Most applications don’t have the stationery product in a stable condition, it will be wise to select 80GHz radar over an ultrasonic device.

	Ultrasonic	Radar
Common Frequency	30 kHz, 240 kHz	80GHz
Microwaves Type	Mechanical waves (Sound waves)	Electromagnetic waves
Dust, condensation, buildup	Huge influence	No influence
Air temperature, pressure	Huge influence	No influence
Air density, and gas composition	Huge influence	No influence
Suitable Application	Simple/stationary measurements (Exp: Water level)	Nearly all types of level measurements
