Radar level transmitters can measure a wide range of media, thanks to their non-contact microwave measurement principle, which is largely independent of physical and chemical properties of the medium.
1. Liquids
Radar level transmitters are widely used for almost all liquid applications, including:
Water, potable water, wastewater
Oils, diesel, crude oil, fuel oil
Acids and alkalis (e.g. sulfuric acid, hydrochloric acid, sodium hydroxide)
Solvents, alcohols, hydrocarbons
Liquefied gases (LPG, LNG, ammonia)
High-temperature or high-pressure process liquids
Radar measurement is not affected by density, viscosity, conductivity, or temperature changes, making it ideal for both clean and aggressive liquids.
2. Slurries and viscous media
Radar level transmitters can reliably measure:
Slurries with suspended solids
Mud, pulp, mining slurry
Sewage, wastewater with sediments
High-viscosity liquids and pastes
Because the sensor does not contact the medium, there is no risk of coating, clogging, or mechanical wear.
3. Foaming media
Radar level transmitters can measure liquids with foam, such as:
Chemical reaction tanks
Fermentation vessels
Detergent, wastewater aeration tanks
High-frequency 80 GHz radar provides better signal focus and penetration through foam, ensuring stable measurement even under heavy foaming conditions.
4. Corrosive, toxic, and hazardous media
Radar level transmitters are especially suitable for:
Strongly corrosive liquids
Toxic or hazardous chemicals
Flammable or explosive media
Since the measurement is non-contact, only the antenna is exposed, improving safety and reducing maintenance.
5. Bulk solids (powders and granules)
With appropriate antenna and frequency selection, radar level transmitters can measure:
Cement, lime, fly ash
Plastic pellets, grain, sugar
Coal, ore, mineral powders
Fertilizer and chemical powders
For solids, radar is preferred over ultrasonic in dusty environments and large silos.
6. Media with changing process conditions
Radar level transmitters perform reliably in processes with:
Rapid temperature fluctuations
Pressure changes or vacuum conditions
Vapor, dust, or condensation
Unlike ultrasonic devices, radar signals are not influenced by gas composition or air conditions.
Summary
Radar level transmitters are suitable for measuring:
Liquids (clean, viscous, corrosive, high-temperature, high-pressure)
Slurries and wastewater
Foaming media
Toxic and hazardous chemicals
Bulk solids and powders
Their versatility makes them ideal for chemical, oil & gas, water treatment, power, mining, food, and pharmaceutical industries.
