ISANO (International Standards for the flow measurements - Active Network Objects) is a project supported by the Croatian Ministry of Science and Technology (Contract No. 353-16-10-2002, October 11, 2002). ISANO provides an object oriented approach to the realization of the software components implementing the international standards in the form of active network objects. The project will illustrate the conversion of the international standards into the software objects consisting of the corresponding input/output parameters, intermediate results, functions, ranges of validity and error status. The project focuses on the implementation of the flow measurement standards only, but we hope that this approach could be applied to the measurement standards in general.

Increasing complexity of the contemporary industrial measurement systems is a common characteristic. The partitioning of the measurement process into the components that can be realized as separate software objects facilitates the development of the measurement system. Using a client/server approach, the measurement system components become shareable and accessible across the network. The components can be deployed anywhere on the network and shared by a considerable number of applications. The project gives the guidelines for the realization of the flow measurement system with distributed software components, i.e., measurement procedures.
