Principles of Good Measurement: Level Interface     

 

LEVEL INTERFACE 

Level interface is caused by the separation of two liquids, the most common being oil and water.  The interface is caused by one of the liquids not being able to mix with the other, possibly because it is a different weight – oil is lighter than water, does not mix well and floats on top of the water Level Interface doesn’t just occur with liquids, because sometimes liquid needs to be separated from solid matter in some processes too.  Interface measurement instruments are used to control the separation of these two products (whether liquids or liquid and solid), and are often the solution used in processing and effluent control. 

The ways in which the interface can be detected are by measuring weight, electrical pulses, and working out the differentials of the products (e.g. oil is lighter, floats and is non-conductive).   VEGA has a range of instruments that detect these differences, either as a switch point, or a continuous measurement of the interface between two liquids, or a solid and liquid.   These ranges are listed below:

Guided Microwave - VEGAFLEX Range

Capacitive - VEGACAP Range

Nucleonic - VEGA OHMART Range

Vibration Solids - VEGAVIB Range

Digital Communications – DATAWARE
