Application challenges
6.5.1
Resolve thin oil layers
The surface readings in applications with thin oil layer on top water can be stabilized by
setting Peak Detection Method to Threshold Intersection.
Thin oil layer on top of water might cause jumpy surface readings. Because of the thin oil
layer, the transmitter varies between detecting oil and water. Sometimes the oil layer gets
too thin to be detected, see

A. Oil peak detected as surface
B. Water peak
C. Surface Threshold
D. Too thin oil layer, no peak
E. Water peak detected as the surface
The surface readings in such applications will be stabilized by setting the Peak Detection
Method to Threshold Intersection. The point used for level measurement is then changed,
