Abstract
Provided is a diagnostic apparatus, including a diagnostic unit configured to diagnose a condition of a vortex flowmeter using a determination result of a magnitude of a signal component of each of at least one target detection signal among the at least one detection signal detected by the vortex flowmeter having a vortex generator and a detection unit configured to detect at least one detection signal according to a vortex generated by the vortex generator, or a magnitude of a signal component of at least one of combined signals configured to linearly combine two or more of the at least one detection signal.

A diagnostic apparatus, comprising a diagnostic unit configured to diagnose a condition of a vortex flowmeter using a determination result of a magnitude of a signal component of each of at least one target detection signal among the at least one detection signal detected by the vortex flowmeter having a vortex generator and a detection unit configured to detect the at least one detection signal according to a vortex generated by the vortex generator, or a magnitude of a signal component of at least one of combined signals configured to linearly combine two or more of the at least one detection signal.
A diagnostic method, comprising:
- acquiring a magnitude of a signal component of each of at least one target detection signal among the at least one detection signal detected by a vortex flowmeter having a vortex generator and a detection unit configured to detect at least one detection signal according to a vortex generated by the vortex generator, or a magnitude of a signal component of the at least one of combined signals configured to linearly combine two or more of the at least one detection signal;
- and
- diagnosing a condition of the vortex flowmeter using a determination result of the magnitude of the signal component.
A computer-readable medium with a diagnostic program recorded thereon, when executed by a computer, causing the computer to function as
- a diagnostic unit, configured to diagnose a condition of a vortex flowmeter using a determination result of a magnitude of a signal component of each of at least one target detection signal among the at least one detection signal detected by the vortex flowmeter having a vortex generator and a detection unit configured to detect a magnitude of a signal component of at least one detection signal according to a vortex generated by the vortex generator, or a magnitude of a signal component of at least one signal component of a combined signal configured to linearly combine two or more of the at least one detection signal.
