Figure 3-5. Disturbing echoes

can be filtered out by creating an

amplitude threshold

1. For best performance execute Measure and Learn with an empty

tank/chamber.

2. Click Measure and Learn, and follow the instructions.

For more information, see the Rosemount 5300 Series Reference Manual

(Document No. 00809-0100-4530) section “The Configuration Mode Tab”.

Probe End Projection

Probe End Projection (PEP) allows you to measure product level when the

surface pulse is too weak to be detected, e.g. long measuring range, solids,

and boiling hydrocarbonates.

1. Make sure there are no disturbing echoes above the surface threshold.

2. In Rosemount Radar Master, click the Guided Probe End Projection and

follow instructions.

For more information, see the Rosemount 5300 Series Reference Manual

(Document No. 00809-0100-4530) section ”Probe End Projection”.

NOTE

This function is only available for liquid/solid product level measurement

modes and a well defined probe end echo (i.e. ensure that the probe

end/centering disc/weight is either always in contact with the tank wall or

never in contact with the tank wall).

NOTE

Probe End Projection is not compatible with Signal Quality Metrics, Dynamic

Vapor Compensation, high DC applications and Interface Measurement.
