摘要
Apparatus and accompanying methods are disclosed for use in a Coriolis mass flow rate meter for providing a mass flow rate signal that has a substantially reduced harmonic content. Specifically, this apparatus measures the Coriolis force induced time interval, Δt, by measuring the time intervals that occur between each of two measurement points (Y₁,X₁) situated on one, e.g. the right, position (or velocity) waveform (747,767) and a reference point (O₁) situated on the other, e.g. left, position (or velocity) waveform (767,761) and which temporally occurs between each of the two measurement points.
