Wide dynamic range ensures universal use
Radar level sensors are particularly well suited for contactless measurement of hydrocarbons because they measure the level independently of temperature, pressure and density. However, the radar signals are reflected very weakly by the relatively low dielectric constants of the different hydrocarbon products. To measure the level of any medium with certainty, the sensors used must be able to detect even the smallest reflected signals reliably. One fundamental contribution to this reliability is the dynamic range of a sensor.
The solution
With a dynamic range of 120 dB, VEGAPULS 64 sets new standards for the detection of even the lowest reflected signals. Especially when measuring the level of hydrocarbons that have poor reflective properties, the high dynamics delivers a significantly increased measurement certainty. This means virtually all media in the petrochemical industry, from crude oil to liquefied gases, can be measured reliably. What is more, the excellent signal focusing enables simple deployment, even when there are heating pipes and other internal vessel structures.
Radar level sensors are particularly well suited for contactless measurement of hydrocarbons.
The benefits
- Reliable level measurement results with all media thanks to high dynamic range
- Virtually unaffected by foam and condensate
- Simple standardization through universal sensor configuration
Expert tip:
A large dynamic range is advantageous particularly in applications with strong foaming. It compensates for the additional signal attenuation caused by the foam surfaces.

Level measurement and point level detection in tanks for liquid fuels
Large amounts of energy are needed to burn clinker in rotary kilns. Substitute liquid fuels such as spent oils or recovered solvents are often used for this purpose. The fuel storage tanks often contain a mixture of solvents, which can produce fumes and vapours in the air space. Due to the large amount of energy needed in cement production, the fuel inputs represent a significant cost factor, so accurate level measurement is essential.

Hexane storage tank
Level measurement and point level detection in hexane storage tank
In pharmaceutical production, Hexane is a commonly used solvent and reaction medium, as well as an agent for oil and grease extraction. This colourless liquid has a slight petrol odour and is highly volatile light hydrocarbon, readily forming highly flammable vapour-air mixtures. When the tank is emptied, no residues may remain inside. Reliable level measurement and overfill protection is an absolute necessity for safe storage and handling.

Liquid waste buffer tank
Level measurement and point level detection in buffer tanks for liquid waste
In preparation for proper disposal, liquid wastes that arise in the production of pharmaceuticals are temporarily stored in buffer tanks. These potentially hazardous mixtures consist of diverse media with very different properties including dielectric conductivity (dielectric constant) and density. For optimal storage, reliable and accurate level measurement is required. Point level detection ensures overfill and dry run protection.
