Mounting Levelflex FMP55 HART

• 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).
The spacer is also available as an accessory: → 101.
• 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.
