The National Measurement Institute (NMI) delivers the most accurate liquid flow measurement services in Australia. We calibrate our clients’ instruments that measure liquid flow. We measure liquid flow, and deliver research, advice and training for our clients.
We provide services to Australian laboratories, universities, government and industry. We specialise in calibrating flowmeters, in particular hydrocarbon fuel meters for the fuel industry. We deliver our hydrocarbon liquid flow services at our Londonderry Flow Facility (LFF). We can deliver some services on-site at our clients’ laboratories and facilities around Australia.
Our services include:
We calibrate instruments that measure liquid flow from 5 per minute up to 4000 L/min and pressures up to 2000 kPa. Our uncertainty capability is as low as 0.04%. This means our calibrations are the most accurate in Australia. All our calibrations are traceable to the Australian standards for mass, density, temperature and pressure.
Our calibrations are for clients who need the highest accuracy possible. This includes other NATA accredited laboratories and flowmeter verification service agents. Most accredited laboratories and service agents provide results traceable to the standards we maintain. Clients involved in bulk fuel sales often use our services to maintain confidence with trading partners.
We calibrate most instruments that measure liquid flow. This includes rare and custom-built devices. We calibrate:
We deliver calibration results with the lowest uncertainty capabilities possible in Australia. Our equipment and facilities are the most innovative and advanced because we are responsible for maintaining the standards. We are one of a few facilities in the world capable of calibrating CNG with uncertainties under 0.1%.
Our calibration equipment (flowmeters), flow rate and uncertainty capabilities are:
NATA publish our laboratories flowrate capabilities as part of the accreditation process. For more information about our laboratory’s capabilities for each standard, see the NATA Scope of Accreditation: NMI Mass and Related Quantities Project.
We usually complete liquid flowmeter calibrations in 1 to 2 business days. Wait times from booking to calibration is usually under 2 weeks. We liaise with clients to meet their schedule requirements wherever possible. We can calibrate some instruments sooner if urgent.
We don’t have a price list for calibration services. This is because we customise our services to meet each client’s needs and instruments. Indicative rates for our liquid flow services include GST.
