Abstract
A microwave flowmeter and a flow rate measurement method are provided. The microwave flowmeter includes a transmitting circuit, a detecting circuit, and a computing unit. The transmitting circuit includes a substrate, a plurality of resonator elements, and a transmission line. Two ends of the transmission line receive high frequency electric feedings, so that the resonator elements separately generate corresponding microwaves and each of the microwaves has at least one resonant frequency. The detecting circuit detects offsets of the corresponding resonant frequencies that are caused when a fluid flows through the resonator elements, and records times at which the offsets happen. The computing unit is electrically connected to the detecting circuit, and computes a flow rate of the fluid according to the times at which the offsets happen of the resonant frequencies and locations that are of the resonator elements and that correspond to a flow path.
