Title:
航空機導管モニタリングシステムとその方法
Document Type and Number:
Japanese Patent JP5373894
Kind Code:
B2
Abstract:
The system has pipes (2-4) for conveying gas from a source (1) to a work place (5) i.e. gas outlet. A flow rate determining device (7) determines gas mass flow in the pipes. A pressure determining device (9) determines static pressure in the pipes. A control device (10) compares a normal operation-actual-gas mass flow with a reference gas mass flow and a normal operation-actual-pressure with a reference pressure and emits a signal indicating a deviation, if the normal operation flow deviates from the reference flow and/or the normal operation pressure deviates from the reference pressure. An independent claim is also included for a method for monitoring gas mass flow in pipes installed in an aircraft.
