FIELD: physics.
SUBSTANCE: electronic metering unit capable to detect residual compound in flow-metering device accommodates handling system capable to direct flowmeter to impart flow-metering device to vibration and receive vibration response from flow-metering device, and storage system capable to keep flowmeter parameters and data. Besides, electronic flow-metering unit is characterised by that the handling system is capable to compare vibration response to preset threshold of residual compound for detection thereof.
EFFECT: possibility to control flowmeter drainage level.
