Two or multi-phase medium e.g. fluid`s, physical flow parameter e.g. flow rate, measuring method, involves producing measurement values representing parameter by considering pressure difference of medium and by usage of transfer function

摘要

The method involves allowing medium to be measured to flow through a measuring tube of an in-line measurement device (1). A measurement signal influenced by a physical parameter e.g. flow rate, of the medium is produced using a sensor arrangement of the device, which reacts to the change in the parameter. Measured values digitally representing the flow parameter of the medium are produced by considering a pressure difference of the medium and by the usage of transfer function. An independent claim is also included for a measurement system for measuring a physical flow parameter e.g. mass flow rate, of a medium.
