1 Flange of the displacer chamber
Planning instructions:
•
In normal cases, use a rod probe. When installing into a metallic displacer chamber up to 150
mm, you have all the advantages of a coax probe.
• It must be ensured that the probe does not come into contact with the side wall. Where
necessary, use a center washer at the lower end of the probe (feature 610 of the product
structure).
• A center washer must be adapted as accurately as possible to the internal diameter of the
displacer chamber to also ensure perfect operation in the area of the probe end.
Additional information on interface measurement
• In the case of oil and water the centering disk should be positioned at the lower edge of the
lower disposal (water level).
• The pipe may not exhibit any steps in diameter. Use the coax probe where necessary.
• In the case of rod probes, it must be ensured that the probe does not come into contact with
the wall. If necessary, use a center washer at the end of the probe.
• A plastic center washer has to be used for interface measurement (feature 610, options OD and
OE).
