Claim:
1. A leakage detection system for detecting leakage in a gas supply system comprising a gas source connected to a gas delivery module by a pipeline, the leakage detection system comprising: a flow sensor connectable along the pipeline remotely from an inlet of the gas delivery module; and a detection module configured to receive signals representing a measured flow parameter from the flow sensor, and to compare the measured flow parameter to a stored leakage-free reference value to detect a change in flow parameter in the presence of a leak; wherein a flow resistance between the detection module and an outlet of the gas delivery module amplifies the change in flow parameter in the presence of a leak, wherein the flow resistance comprises a flow resistor element, the flow resistor element being connectable between the flow sensor and the inlet of the gas delivery module.
