The invention relates to a monitoring apparatus for a steam plant, the apparatus comprising: a sensor unit () associated with a component of the steam plant, the sensor unit () being configured to provide an output indicative of the operating condition of the component; wherein the sensor unit () has a plurality of operating modes, each operating mode having a different resource usage; the apparatus further comprising: a selector () for selecting one of the plurality of operating modes; wherein the operating mode is chosen based on a current operating condition of the steam plant. The invention also relates to a method of operating such an apparatus.

Monitoring apparatus for a steam plant and a method of operating such an apparatus

A condensate recovery system may comprise a plurality of drain lines for draining condensate from an associated steam plant. Each drain line may incorporate a steam trap and feeds into a common condensate return line running between the drain lines and a condensate receiver tank. The system further may comprise an acoustic sensor positioned along the common condensate return line, upstream of the receiver tank, for providing an acoustic output indicative of the collective steam loss through steam traps upstream of the sensor.
