Abstract
A differential pressure (dP) measurement device for use in flow measurement including a first microwave resonator () having a flexible or yieldable part or member () deformable or yieldable when subject to a differential pressure in such a way as to alter a resonant frequency of said resonator, and an electronic unit () which is coupled to the resonator (), and where the electronic unit is adapted to produce an output depending on a resonant frequency of the resonator ().
