APPLICATION
Monitor changing surface conditions
CHALLENGE
In some processes it is critical to monitor for changing surface conditions.
Mixing of different fluids and temperature variation are common in batch
processes. If unwanted foam, boiling, or emulsions occurs, the batch might
be spoiled. In addition, surface changes that go unnoticed could result in
overfilling and further problems downstream.
When batch processes require both level and surface condition
monitoring, plant personnel may utilize multiple measurement methods
to monitor these conditions. This requires additional maintenance and
additional process connections. If a vessel is limited to only one process
connection, plant personnel may resort to manual or visual methods of
monitoring surface conditions. These methods can be both time
consuming and unreliable.
Unwanted surface conditions can lead to several negative business results.
When these conditions go unnoticed, the result is poor product quality and
potential product waste or rework. If the batch is ruined or needs further
processing, additional time and resources are needed thereby increasing
operations costs and decreasing plant throughput. Significant foaming
can also overflow the tank releasing process materials into the
environment.
SOLUTION
To help monitor changing surface conditions, the Rosemount 5300 Guided
Wave Radar can be utilized with Signal Quality Metrics. Guided Wave Radar
technology reliably measures level in changing surface conditions and it is
minimally impacted by the presence of foam or boiling. As a feature of the
PlantWeb Diagnostic Suite, the Rosemount 5300 calculates Signal Quality
and outputs a value from 0 to 10.

conditions may lead to product quality issues
downstream.
VALUE PROPOSAL
A value of 10 indicates a strong signal and no process noise. A significant
change in the Signal Quality value might indicate changing surface
conditions. If foam is present, the Signal Quality would drop in value. Level
and Signal Quality can be sent to the control room as process variables and
monitored over time.
8000 mV signal strength
Figure 2. This tank plot demonstrates a strong surface signal with a
corresponding high signal quality value.
6000 mV signal strength
Figure 3. Due to foam on the surface, this tank plot demonstrates a weakened
surface signal with corresponding reduced signal quality value.
VALUE PROPOSAL
Customers with batch processes subject to changing surface conditions
can experience a variety of positive outcomes with the unique capabilities
of the Rosemount 5300. They are able to continuously monitor level, while
getting the added benefits of surface monitoring. The signal quality
diagnostics can help identify changing surface conditions, which in turn
helps maintain high quality batches and prevents waste or rework. By
maintaining good quality, customers are able to increase throughput and
decrease operations costs. Lastly, the ability to quickly recognize an
unwanted surface change reduces the risk of tank overfills caused by these
conditions.
