This unit of competency is applicable to verifiers who operate under a licence to test and mark specific classes of liquid measuring instruments tested using a volume measure only. They may also undertake sales, installation and/or repair of liquid measuring instruments. Liquid measuring instruments are used in a very wide range of commerce. For example, petrol bowsers measure fuel at the point of sale and flowmeters are used to measure bulk commodities such as milk, chemicals and petroleum products during production and distribution. Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These are found at the end of this unit of competency under the section 'This competency in practice'. |

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | Competency must be demonstrated in the ability to perform consistently at the required standard for one class of liquid measuring instrument listed in the Range Statement. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors should ensure that candidates can: identify, access and apply test procedures identify and use suitable reference standards install and repair liquid measuring instruments to meet statutory requirements evaluate and adjust the impact of the operating environment on the performance of the instrument analyse test results to determine the instrument's suitability for verification (trade use) maintain the security and confidentiality of data in accordance with organisational and regulatory requirements report results in the required formats and expected timeframe. |
Context of and specific resources for assessment | This unit of competency is to be assessed in the workplace or simulated workplace environment. This unit of competency may be assessed with: MSATMREF301A Use and maintain reference standards. Resources may include: liquid measuring instruments using volume measures, test equipment and reference standards computer and relevant software and/or organisation information management system Certificates of Approval for instruments relevant legislative and organisational procedures. |
Method of assessment | The following assessment methods are suggested: questions to assess understanding of relevant procedures and remedial actions review of verification reports prepared by the candidate feedback from supervisors and peers regarding the candidate's ability to verify the performance of instruments in accordance with legislative and organisational procedures. In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. Questioning techniques should suit the language and literacy levels of the candidate. |
This competency in practice | Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. A service station operator of a large company owned site requests a servicing company to visit their site as he has noticed that one fuel dispenser has a faulty display and the service station appears to have inconsistent dip reading. The verifier arrives and introduces himself and informs the owner that under their contract all fuel dispensers are due for checking. The verifier completes a safety check, AIP clearance form and asks about the location of the fuel return points. The verifier then blocks the lane next to the fuel dispenser, puts safety signs, barricades and test measures in place and ensures that the work area is safe.The verifier repairs the faulty display and proceeds to test the fuel dispenser. He visually checks the fuel dispenser against the Certificate of Approval and checks for any leaks noting any discrepancies on a verification report form. He then tests the fuel dispenser as per the National Test Procedures noting results on the test report and returning dispensed fuel to the storage tanks in a safe manner. The verifier finds the fuel dispenser is outside the maximum permissible error and adjusts the dispenser. After repeating the National Test Procedure, he finds the dispenser is within the maximum permissible error and then seals and marks the dispenser with his mark. The verifier then tests the other fuel dispensers on-site. Some require adjustment before being verified and marked. Another dispenser is within the maximum permissible error and does not require adjustment. One dispenser cannot be adjusted within the maximum permissible error and the verifier removes the mark. After all dispensers are tested, the verifier completes the verification forms, fuel usage form and AIP form. The verifier informs the site manager that one dispenser cannot be used as it is non-compliant and issues a non-compliancy form. The site manager locks the dispenser until repairs can be made. The remaining forms are given to the site manager and the verifier departs. |
