The primary reference standard for open channel flow measurement, AS3778, clearly advocates the need for measurement uncertainty characterisation. It also explains how to calculate measurement uncertainty. This then poses the question·- why have so few measurement companies and clients taken it up and used it? This paper explores this question by looking at several case studies of measurement uncertainty calculation and use, with particular emphasis on identifying the issues and perceptions preventing or restricting its uptake.
