Interfaces, that is, boundaries between separation layers, can be found everywhere in the process industry, e.g. in the chemical or oil & gas industry. An interface arises when two media with different densities are filled into a container: for example, water and oil. To separate the two media from one another, it is necessary to determine where the transition from one medium to the other is located. VEGA sensors can be used to measure both the total level and the interface reliably.
VEGA uses the following physical measuring principles for interface measurement:
