Many industrial processes involve separating oil from water. Measuring only the overall liquid level is often insufficient because operators also need to know exactly where the oil layer meets the water layer. An Oil Water Interface Level Sensor continuously measures this boundary, helping industries improve separation efficiency, reduce product losses and optimise process performance.
From refineries and wastewater treatment plants to marine and chemical industries, accurate interface measurement plays a vital role in ensuring reliable operations.
An Oil Water Interface Level Sensor is a specialised instrument that measures the interface between oil and water inside tanks, separators and storage vessels.
Unlike conventional level sensors that detect only the total liquid level, an interface level sensor identifies the exact position where the oil layer meets the water layer.
The measurement data is continuously transmitted to control systems, allowing operators to monitor separation processes in real time.
Accurate interface measurement improves operational efficiency and process control.
Maintain the correct oil-water boundary for efficient separation.
Prevent valuable product from being discharged with wastewater.
Provide continuous data for automated separation systems.
Reduce reliance on manual level checks.
Help manage oil-water separation more effectively.
Provide stable measurements even in demanding industrial environments.
Different technologies are available, but the operating principle remains similar.
Continuous monitoring helps maintain efficient and stable separation processes.
The best technology depends on the application, operating conditions and required accuracy.
One of the most widely used technologies for highly accurate oil-water interface measurement.
Measure changes in electrical capacitance between oil and water layers.
