    Legal metrology capabilities 

    Verifying Authority

    As a verifying Authority the AFMG is able to test and seal water meters under National Measurement Regulations 1999. 

    As an independent Calibration and Testing laboratory the AFMG is not owned by a Utility Meter manufacturer, or Water Supply organisation. 

    Approving Authority

    As an Approving Authority, the AFMG is able to pattern approve meters under the National Measurement Regulations 1999. 

    As an instrument of trade measurement, water meter models are increasingly being required to have pattern approval. Initially this was only required for 20mm domestic potable water meters, however now it is extending to larger urban and non-urban meters. 

    The AFMG is capable of initially verifying meters to both NMI R 49 and NMI M 10. For more information on legal metrology refer to the website of the National Measurement Institute

  • Electrical EMC Immunity Testing minus-thick plus-thick

    The Australian Flow Management Group (AFMG) have the capacity to test electrical components to several immunity standards. These tests are conducted and reported against Australian and/or international standards.

    We also offer testing of electrical equipment to determine Ingress Protection (IP) ratings or IP68. The commissioning and use of this system is based on two standards:

    • AS 60529 Degrees of protection provided by enclosures (IP Code)
    • IEC 60512-11-8 Section 8: Test 11h _ Sand and dust

    With respect to NMI M 10 and NMI R 49, the AFMG is capable of conducting these IP rating tests on water meters.

    Most of the testing services offered are covered by the AFMG's NATA scope of accreditation.

    Specification and capability

    • Electrostatic Discharge (ESD) testing in accordance with NMI M 10, AS/NZS 61000.4.2, IEC 61000-4-2, EN 61000-4-2
    • Fast transients: NMI M 10, AS/NZS 61000.4.4, IEC 61000-4-4, EN 61000-4-4
    • Voltage dips, short interruptions and voltage variations: NMI M 10, AS/NZS 61000.4.11, IEC 61000-4-11, EN 61000-4-11
    • RF immunity testing in accordance to Radiated Immunity: NMI M 10, NMI R 49, AS/NZS 61000.4.20, IEC 61000-4-20, & EN 61000-4-20 in the frequency range 20MHz to 6GHz. Note that this RF immunity testing is not currently (June 2012) covered by our NATA accreditation.
  • Radio Frequency (RF) Immunity Testing minus-thick plus-thick

    The Australian Flow Management Group are able to performance test products to RF immunity requirements.

  • Full-scale Hydraulic Testing minus-thick plus-thick

    The Australian Flow Management Group can be engaged to conduct full-scale testing of hydraulic components either in the field or within the laboratory.

    Examples of full-scale hydraulics testing previously conducted by our facilities include: 

    • Gross pollution traps performance testing
    • Road drainage performance testing
    • Stormwater treatment/improvement devices
    • Smart metering field studies
  • Physical Hydraulic Model Studies minus-thick plus-thick

    The Australian Flow Management Group (AFMG) can be engaged to conduct hydraulic modelling of systems or components. 

    This can be an effective risk mitigation tool for large hydraulic projects. The relatively small input cost of the modelling can save the major cost of having to modify a substantial piece of infrastructure after construction. Further, data obtained from running flow scenarios can be used to optimise other components in a connected network.

    Examples of hydraulic model testing conducted by the AFMG include:  

    • Fishway hydraulic models
    • Locks and weir system modelling
    • Power station cooling water hydraulic models
    • Surface water models for creeks, drainage systems, stream flows and other modelling
  • Irrigation Equipment Testing minus-thick plus-thick

    The Australian Flow Management Group (AFMG) were first established to undertake testing and research of equipment for the irrigation sector, and this capacity remains one of our strengths.

    Testing and research of irrigation equipment conducted over the years includes a wide range of, pipes, pipe fittings, valves, emitters, drippers, time taps, moisture sensors and other irrigation components. Testing can range from dripper emitter rates to studies into the effect of droplet size in centre pivot irrigation.
