Probe End Projection

Probe End Projection allows you to measure product level when the surface

pulse is too weak to be detected, such as long measuring ranges, solids, and

boiling hydrocarbons. The calibration should be completed first with an empty

tank during cold commissioning, and then a second time with a filled tank, but

do not overwrite the empty tank calibration.

1. Make sure the surface echo is above the threshold

2. In Rosemount Radar Master click 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

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

Vapor Compensation, Interface Measurement, and High DC applications.

Verification Procedure

Step 1. Verify the

Correctness of Level

Reading

At normal operating conditions, compare the transmitter level, or interface

reading, with an independent measurement. Unfortunately, it often happens

that two independent measurements will not match up perfectly, but check the

sanity and the acceptable deviation.

The independent measurement can be done using a number of different

complementary devices, ranging from sight-glasses and hand-dipping to

redundant differential-pressure and displacer.
