Claim 0:
1. A diagnostic apparatus, comprising
a diagnostic unit configured to diagnose a condition of a vortex flowmeter having a vortex generator using a determination result of a combined signal component of each of at least two target detection signals among a plurality of detection signals detected by the vortex flowmeter, the diagnostic unit storing a change over an elapse of time of the combined signal component of each of the at least two target detection signals, the diagnostic unit being further configured to predict a future time that the vortex flowmeter will be abnormal based on a predicted determination result that a normalized magnitude of the combined signal component of the at least two combined signals is greater than a first threshold, and equal to or less than a second threshold; and
a detection unit configured to detect the plurality of detection signals according to a vortex generated by the vortex generator.
