SOLR provides flexibility – you determine from the drop down menu what you continuously measure, plot and report.

The OLR is used in conjunction with custom developed software specific for the sensor system. The SOLR has three key functions:

1. SET-UP OF PROCESS MONITORING AND QUALITY CONTROL PARAMETERS
The OLR provides a viscosity curve that characterises the material in the pipe. The option to view three frequency points from the viscosity curve allows the plant engineer or QC technician to see the quality and reproducibility of the product throughout the production process/shift. Each point chosen has upper and lower limits set as a QC band PASS/FAIL determination.

PROCESS MONITORING the engineer or QC technician has the option to establish a step-wise QC file that will track and plot successive process steps or stages.

CONTINUOUS MONITORING for an unchanged product in the pipe line a single stage QC file is applied.

FACTORY PLC uses the settings from the QC stages and compares them with the data streaming from the OLR to the PLC.

ALARMS from SOLR or the factory PLC can be activated if the product viscosity or temperature drifts out of specification.

INFORMED DECISIONS about the process and product trends through the SOLR operator interface are able to be made by the engineer or QC technican.

AUTOMATIC DATA STORAGE of all data and curves are automatically saved and can be recalled at any time for diagnosis of product trends and production issues.

2. MONITORING AND CONTROL OF PROCESS EITHER THROUGH SOLR OR THROUGH THE FACTORY PLC
SOLR provides control and monitoring of your production process and can be used in standalone mode. The operator is provided with a visual cue regarding the trends and quality of the material in the pipe. A visual PASS/FAIL display is shown on screen, plus the actuation of an audio (horn) or visual (strobe) alarm can be provided.

The operator controls the selection of the process stage from the QC file and initiates successive QC process stages. Each stage has the preset QC parameters installed from the set up. When the process stage is completed, the engineer or QC technician manually selects the next stage and the screen provides the pre set parameters for monitoring.

For continuous monitoring of an unchanging product in a pipeline, a single stage QC file is used. The operator screen will display the long-term viscosity and temperature trends of the material.

3. OUT-OF-SPECIFICATION PRODUCT DIAGNOSIS
If the product is out of specification, the plant engineer can recall the complete curve from the time where the drift out of specification occurred, and open it using SOLR or using readily available software (text files or MS excel).

Historical data curves can be uploaded into SOLR, so that out-of-specification material can be compared with in-specification data.

Based on these comparisons a diagnosis as to why there is a change in the product quality from what is normally expected is addressed. Considerations include: missing or insufficient ingredient, incorrect amount of heating or shear.
