1. An apparatus for detecting agents in a fluid delivery system in which fluid flows through a fluid conduit, the apparatus comprising:

  • an agent sensor adapted to be coupled to the fluid conduit for providing agent signals in response to agents sensed in the fluid conduit, said agent signals having an age; and

    a processor configured to receive the agent signals, determine weighted agent signals by applying weighting values to agent signals giving differing weighting to different agent signals depending on the age of each agent signal, and determine an agent concentration value from the weighted agent signals.
