Interface Level Measurement is a specialized process used to detect the boundary between two immiscible liquids within the same vessel, such as oil and water. This is essential for efficient separation processes, ensuring that only the correct medium is drawn from the tank while maintaining high product purity and environmental compliance.
Nuicon supplies and distributes Interface Level Measurement technology engineered for long-term stability and precision. Whether managing separator tanks in oil and gas or settling vessels in chemical plants, our instruments provide the high-fidelity data required for complex industrial automation and phase separation.




We distribute sensors with traceable certification to ensure the boundary detection is accurate for critical separation.
Available with exotic alloys and coatings to handle aggressive emulsions and corrosive chemicals.
Our interface sensors provide both the total level and the interface level in a single process connection.

It is the distinct layer where two different liquids meet, such as the line between water at the bottom and oil floating on top.
Guided Wave Radar (GWR) is the industry standard, as it uses microwave pulses that partially reflect off the top liquid and the interface layer.
Yes. For accurate measurement, the two liquids must have different dielectric constants and must not be fully emulsified.
Most standard interface sensors track two distinct layers; however, specialized models can provide data on “rag layers” or multiple interfaces.
Absolutely. We supply high-pressure, high-temperature models designed specifically for oil/gas and chemical separation vessels.
Yes, we provide NABL Calibration to verify that the sensor correctly identifies the interface height against physical standards.
