Method for measuring a phase difference

摘要

The invention relates to a method and a device, in particular for use in Coriolis mass through-flow apparatuses, with the aid of a processing unit (4), in which a first periodic signal and a second periodic signal, with the phase difference, with respect to the first periodic signal, which is to be determined, are applied to the processing unit (4) and a phase-synchronous third periodic signal is derived from the second periodic signal by the processing unit (4). The known method and the known device are improved according to the invention in that, using a delay element (5), the third periodic signal is derived directly from the second periodic signal. <IMAGE>
