APPLICATION
Level measurement of sticky materials or slurries
CHALLENGE
In process tanks with sticky materials or slurries, measurement equipment
can quickly become coated. If the device gets coated, it may not perform
as expected. For level measurement devices, this coating may result in loss
of the actual level measurement.
Plant personnel might use non-contacting measurement technologies to
minimize the exposure to process coating. In applications where use of
non-contacting technology is not possible (i.e. certain installation
constraints, interface, angled or slanted surfaces) then Guided Wave Radar
or Displacer technology may be used. Displacers are a mechanical
technology. Process coating can quickly disable the movement of the
displacer leading to the loss of the process variable. Guided Wave Radar is a
superior alternative as no moving parts are exposed to the process
materials. However, excessive probe coating may reflect a signal stronger
than the actual process surface leading to an incorrect process variable. To
prevent this, operators usually monitor the radar signal quality manually
and interpret when the probe needs cleaning.
The challenges of process coating can lead to several negative business
results. If the level measurement is lost then there is a risk of the tank
overfilling or running dry. Overfilling a tank can result in a spill and lost
product. It may also lead to extensive clean up and potential environmental
penalties. If the tank runs dry, the process may shut down, and pumps can
be damaged resulting in repair or replacement costs. A measurement
device failure leads to unplanned maintenance and a possible process
shutdown. Lastly, risk of overfill or a false reading can lead to safety risks.

SOLUTION
To address concerns of process coating, the Rosemount 5300 Guided Wave
Radar with Signal Quality Metrics can continuously monitor signal quality.
The signal quality can be reported as a process variable. A value of 10
represents a clean installation with no process noise. As the value of the
signal quality decreases, the risk increases of misidentifying noise or
process coating as the true level. With this diagnostic functionality, the
condition of the probe can be checked while remaining in service.

corresponds with the high Signal Quality value.

which corresponds with the decrease in Signal Quality value.
VALUE PROPOSAL
Customers can experience a variety of positive outcomes with the unique
functionality of the Rosemount 5300. Plant personnel are able to
continuously monitor level and prevent costly tank overfills, pump
cavitation and damage, and unplanned shutdowns. Signal Quality Metrics
simplify coated probe diagnostics, eliminate the need to interpret tank
plots, and provide information that supports a preventative maintenance
program. And lastly, safety risks are reduced by preventing unnecessary
maintenance and tank overfills.
