• Within the measuring range, the probe must not get into contact with the pipe wall. If necessary,
secure the probe by retaining or tensioning. All rope probes are prepared for tensioning in
containers (tensioning weight with anchor hole).
• Within the measuring range, the probe must not get into contact with the pipe wall. If necessary,
use a PFA centering star (see feature 610 of the product structure).
• Coax probes can always be applied if there is enough mounting space.
For bypasses with condensate formation (water) and a medium with low dielectric constant
(e.g. hydrocarbons):
In the course of time the bypass is filled with condensate up to the lower disposal and for low
levels the the level echo is superimposed by the condensate echo. Thus in this range the
condensate level is measured instead of the correct level. Only higher levels are measured
correctly. To prevent this, position the lower disposal 100 mm (4 in) below the lowest level to
be measured and apply a metallic centering disk at the height of the lower edge of the lower
disposal.
With heat insulated tanks the bypass should also be insulated in order to prevent condensate
formation.
