FIELD: physics, measurements.
SUBSTANCE: method and device are suggested for diagnostics of operation of pulse pipeline in technological metering device (flow metre) in technological process. Source (144) of vibration signal configured for transfer of acoustic signal along pulse pipeline (112), and receiver (146) of acoustic vibration signal from pulse pipeline are connected to technological connection element (110), through which line (112) passes. Diagnostic circuit (140) contained in technological detector (102) of metering device, on the basis of accepted acoustic vibration signal diagnoses pulse pipeline (clogging or leakage of filling liquid). Technological detector (102) comprises flow pressure detector or flow level detector and for provision of power supply it is connected to double-wire control circuit of technological process. Diagnostic circuit may be configured for self-diagnostics based on accepted acoustic signal.
EFFECT: improved reliability of technological process control due to possibility of anticipatory diagnostics of flow metre failures.
