Keep the stream, output, configuration and accepted reference evidence together when handing a kraft measurement to the operating team.
A kraft project can involve several measurement points with different chemistry and solids. A handover headed only ‘9600 Series’ leaves important questions unresolved: which model was selected, what does the output represent and which operating conditions were actually checked?
Rhosonics describes CDM 9670 and 9680 duties for dissolved and suspended solids in pulp and paper processing. Its Canadian paper-mill case concerns a CDM 9670 measuring lime mud before a rotary kiln. That named duty does not demonstrate suitability or performance on every liquor stream.
This PMA application sets out a separate handover record for each proposed measuring point. Use it when comparing proposals, reviewing commissioning evidence or transferring responsibility to operators. Keep the drawing, configuration and reference evidence tied to the same line tag.
Create a new record for each liquor or lime-mud duty. Do not carry a result, calibration or acceptance decision from one stream into another without review.
Record the exact stream name, line tag and neighbouring process stages. Mark the sensor and sample points on the drawing, including any dilution, mixing or separation between them.
Keep green liquor, white liquor, weak black liquor and lime mud individually identified where they form part of the project. Record the material actually present during commissioning.
Name each required output and its units: slurry density, dissolved solids, suspended solids or another confirmed result. State which reference method determines each quantity.
Where a result is reported as a chemical concentration or equivalent, document the calibration basis. Do not treat a density reading, a total-solids result and a specific chemical analysis as interchangeable.
Record the actual model, sensor or fitting arrangement, calibration identifier and output scaling. Include the approved operating ranges and the relevant materials and access requirements.
Link the configuration to the selected stream and retain the as-installed drawing. The broad product-family description should not substitute for the specific instrument documentation.
Attach representative reference comparisons with timestamps, operating conditions and the active configuration. State the tested range and any relevant conditions that have not yet been covered.
Record scaling, deposits, abrasion or maintenance observations where relevant to the selected point. Keep unresolved measurement issues visible rather than closing them through a paperwork label.
The operating team needs to know what the result supports and when its applicability must be questioned. Keep this responsibility clear for every measurement point.
Record the duty and range accepted by the responsible team, the decision supported by the signal and the response to unavailable or suspect readings. Preserve the process’s independent operating protections.
Name who owns reference checks, configuration changes and maintenance observations. Define which stream, chemistry, temperature or installation change will trigger another applicability review.
Send the individual stream records, proposed outputs, model documentation, process drawing and reference comparisons. PMA can help resolve the measurement specification and evidence needed before the operating handover is accepted.
This handover record adds an auditable duty and responsibility record to the specialist kraft guidance. Images illustrate process review; they do not depict a particular paper-mill installation.
Review the PMA 9600-family page, then confirm the exact model and configuration for the proposed liquor or lime-mud duty.
Read the specialist kraft library and the manufacturer’s pulp and paper context. The Canadian lime-mud example is a separate, named case rather than a general performance guarantee.
