• The configured dielectic constants are included in the evaluation of the echo peak
amplitude and should therefore also be set correctly.

7.10.4 Interface Level with Submerged Probe
The measurement mode Interface Level with Submerged Probe is used to handle interface
measurements when the product level is not visible, for example in a full chamber pipe as
illustrated in
and only the interface level is detected by the transmitter.

with Submerged Probe Measurement Mode
A. Interface distance
B. Interface level
C. Product level is ignored
D. Interface level is measured
Even if the upper product level drops, it is ignored by the transmitter which continues to
measure only the interface level. If the product level drops, the air filled region in the
upper part of the pipe will slightly reduce the measurement accuracy of the interface level.
To achieve high accuracy in this measurement mode, the probe must be fully submerged,
or a Rosemount 5302 for Level and Interface measurements should be used.
Set the measurement mode using Rosemount Radar Master
To set the measurement mode to Interface Level with Submerged Probe:
Prerequisites
Note
Do not set measurement mode to Interface Level with Submerged Probe for applications
where both product level and interface level should be measured.
