ABSTRACT:
Certain embodiments of the invention relate to an apparatus for fluid leak detection. The apparatus includes a fluid supply conduit for supplying fluid to an external structure and a substantially parallel fluid return conduit for carrying fluid away from the external structure. The apparatus further includes: an oscillator for causing a separation of the fluid supply conduit and fluid return conduit to vary over time; sensors disposed relative to the conduits to measure the separation at respective opposed portions of the conduits; and a processor coupled to the oscillator and the sensors. The oscillator is responsive to the processor and receives respective separation measurement signals from the sensors. The processor is configured to determine whether there is a difference between a supply fluid mass flowing in the fluid supply conduit and a return fluid mass flowing in the fluid return conduit based on the separation measurement signals.
