The FME is a server-side web application that assesses the theoretical (Type B) uncertainty of industrial flow measurement systems.
The FME is built using the Python computer language. Various additional Python packages are used.
The Django web framework provides a platform to host the system on a web server such that users can access a central database of measurements across a network.
The Python Uncertainties package is essential for correctly equating the propagation of uncertainties. This package transparently handles calculations with numbers and uncertainties (like 3.14±0.01), but can also yield the partial derivatives of any expression. This function is essential for the FME as it allows combining uncertainties with different units.
The FME uses a general model to combine individual sources of uncertainties of head-type flow measurements.
