ANORDNING FOR OVERVAKNING AV FLODET I HYDRAULSYSTEM I SYFTE ATT AVKENNA EVENTUELLT LECKAGE

摘要

A hydraulic system is supervised in order to detect leakage by comparing the flows in two conduits of a hydraulic power consumer. Rotatable flow sensitive means are mounted in each of the conduits. Means are provided to indicate the change of the rotational speed of at least one of the flow sensitive means caused by leakage in the hydraulic system.
