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.
The benefits
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.
