Microwaves are respectively propagated through a reference fluid and fluid to be measured, both contained in a detection pipe body, and as a result, a first phase lag .theta. 1 and a second phase lag .theta. 2 can be determined on the basis of the microwaves by a phase lag measuring circuit. Then, a density computing circuit subtracts the first phase lag .theta. 1 from the second phase lag .theta. 2 to determine a phase difference .DELTA..theta.. When computing the density of matter in the fluid on the basis of the phase difference .DELTA. .theta., the density computing circuit performs density computing processing such that a real second phase lag .theta.2 satisfies the following equation .theta.2 = .theta.2' + N x 360° where N is the number of rotations, and .theta.2' is an apparent phase lag obtained by the phase lag measuring circuit. Then, if the density does not fall within a checking range defined by upper and lower limit values, a rotation-number checking circuit increases or decreases the number N of rotations such that the density falls within the checking range.
