Short Desciption:
Theory overview of flow measurement using differential pressure devices based on ISO-5167 standard.

Summary:
Differential pressure flow measurement is old and reliable. With the aid of microprocessor technology now discharge coefficient calculations can be done in real time. Even more, properties of the fluid can be stored on the instrument and measuring temperature and absolute pressure allows to correct fluid parameters such as density and viscosity and then to obtain the mass flow rate. This are called multivariable mass flow meters. By other side years of research and experiments had been done obtaining better characterization of typical differential pressure devices (nozzles, orifice plate , etc). The ISO5167 standard condenses all this experimental information giving the formulas and procedures for manufacturing a differential pressure flow measurement device of the standard types with a predictable uncertainty.
