Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
Emplacement may include:
sumps, pipes, civil structures
pits, concrete structures
Meter type may include:
electromagnetic
ultrasonic (Doppler, transit time)
mechanical meters (propeller actuated, turbine)
systems of automated or manually operated weirs and gates with flow measurement capability
open channel flumes and thin-plate weirs
channel or stream gauging emplacements
Faults may include:
weeds and other obstructing materials
dirty solar panels
blockages and leakages of pipes and channels
leaking/seeping channel banks
animal infestations (wasp nests, ants and spider webs, bird nests, yabbies)
electrical interference
distortion of pipes
flow disturbance factors
Asset condition checklist may include:
visual clues - leaks, breaks, seals, vandalism or tampering, wiring, tags and verification marks
validated third-party reports
display outputs - fault codes
erratic or inconsistent data readings
water quality, water flow (flow rate and full pipe)
operating parameters of the emplacement & meter (eg full flowing or partially full; operating range with respect to flows)
electrical interference
check of security seals
Rectify may include:
unblocking/ desilting
ensuring flanges etc are tight
replacing components according to organisational guidelines
Components may include:
sensors
chips
cogs
spindles
transducers
outputs
probes
connectors
wiring
seals & guides (doors & valves)
actuation system
chargers & batteries
Record faults may include:
asset condition checklist
meter condition report
Organisational procedures and statutory requirements may include:
maintenance plan
manufacturers guidelines
Australian Technical Standards

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the following is essential:
confirms the site and the meter
checks meter condition
replaces components as required
documents the maintenance
Context of and specific resources for assessment
Assessment must ensure:
access to a range of meters and installation sites
access to organisational documentation
observance of OHS guidelines
A range of assessment methods should be used to assess knowledge. The following examples are appropriate for this unit:
written questions
oral questions on the job during the maintenance process
written reports including asset condition checklist, meter condition report
third party reports from workplace supervisors
A range of assessment methods should be used to assess skills. The following examples are appropriate for this unit:
demonstrations of meter maintenance in a workplace environment
written Reports including asset condition checklist, meter condition report
third party reports from workplace supervisors
Assessment should be based on evidence which has been gathered from a number of meter installations in a range of conditions which reflect a predictable variety of routine requirements and the range of variables, as well as which allow the potential for applying knowledge and skills in some conditions which require problem solving and contingency responses.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice
a decision of competence only taken at the point when the assessor has complete confidence in the person's competence over time and in various contexts
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.
