After the crude oil arrives at the Vohburg site, the water must first be removed from the emulsion in an electrostatic desalinator before further processing. Sensors of the VEGAFLEX series now deliver precise values to ensure that the process separating the water and oil layers runs effectively.
During the development of the VEGAFLEX Series 80 sensors at that time, the focus was not only on simple instrument selection and guided setup, but also on reliability and measurement certainty. The greatest advantage of the sensor: It delivers exact values regardless of media properties such as density or dielectric constant. Besides that, its distinguishing features are a robust mechanical design and a second process seal. It can be used at temperatures from -196 to +450 °C and pressures from -1 ... +400 bar.
In interface measurement with guided radar, the radar pulses are guided along a cable or rod probe and reflected by the product surface. The measuring probe of the TDR sensor ensures that the signal travels down to the product undisturbed. The series consists of four different instrument types, each of which is tailored to a particular application. VEGAFLEX 86 is often used for high temperatures and high pressure applications, e.g. in distillation columns or in crude oil processing. It has a ceramic insulation and graphite seal in the coupling that can withstand the penetration of steam at a maximum pressure of 400 bar and temperatures up to 450 °C. The spacers in the coaxial probe are also made of ceramic and mechanically stable enough to withstand the vibrations and shocks.
