Solve problems in density/level measurement components and systems

Assessment tool

Version 1.0
Issue Date: May 2024


This unit involves the skills and knowledge required to set up density/level measurement components and systems and provide solutions to a problem as it applies to a process and control work function.

It includes working safely, setting up and calibrating density/level measuring components and systems, applying problem-solving techniques, using of a range of measuring devices, and providing solutions derived from measurements and calculations to problems in density/level measurement components and systems.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
