Abstract
An aircraft conduit monitoring system includes conduit that conducts gas from a source to a point of application. A flow sensing device and a pressure sensing device are provided within the conduit. At least one set value of a gas mass flow rate and at least one set value of a pressure are sensed in a learning mode of operation. The set values are compared with sensed actual values in the normal mode of operation. A gas volume flow rate can also be sensed and processed instead of a gas mass flow rate.
