Abstract:
A differential pressure (dP) measurement device for use in flow measurement including a first microwave resonator (1) having a flexible or yieldable part or member (4) 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 (12, 14) which is coupled to the resonator (1), and where the electronic unit is adapted to produce an output depending on a resonant frequency of the resonator (1).
