For interface measurement a few criteria have to be fulfilled:

• The dielectric of the UPPER product must be known and should not vary.
• Upper product dielectric < Lower product dielectric.
• Difference between dielectrics depends on the upper product thickness, but a guideline is > 10(3300) > 6(5300).
• Thickness of upper product > 10 cm (4 in.) for coax, rigid twin and rigid single probes and 20 cm (8 in) for flexible twin probes in order to be detected.
• The max measuring range is limited by the upper product dielectric CONSTANT.
• Coaxial, Twin probes or rigid single can be used.
• Max upper product DC is 5 for twin lead probes and 10 for coaxial probe.

Target APPLICATIONS include interfaces between oil/oil-like (DC < 3) and water/water-like liquids (DC > 20). Consult FACTORY regarding other interface applications and when emulsion layer!
