OPTOLUTION realised in July/August 2015 on-site-calibrations at seven large bulk water meters (DN 600 to DN 1000) at pipes for potable water in the surrounding of a large Australian city. The customers of this service were an international professional service company and the local supplier for potable water in this region. The main goal of the measurements was to create a better metrological and secured base for billing and cost allocations between the involved business partners.
To prepare and realize the measurements the underground pipelines were excavated in holes and shafts. The realisation of the optical accesses was conducted without any disruption of the water-supply. For each calibration a separate measurement uncertainty was calculated.
