摘要： The disclosure describes a fluid level detector in which two identical fluid jet devices, each comprising a fluid jet nozzle and a receiver, are placed in a fluid container. One such device is located below the nominal fluid level in the container and the other is located at the maximum desired fluid level therein. The degree of pressure recovery in each of the receivers depends upon the presence or absence of fluid at that device, and a differential pressure sensing means to sense differences in the recovered pressures is provided to indicate presence or absence of liquid at the upper device.

摘要： A device for detecting leaks of a predetermined magnitude from fluid-containing apparatus, which device comprises an oversized drain tube skewed with respect to vertical and including a cup defined in part by the tube''s lower interior wall so as to collect fluid flowing on the wall. The cup contains a small hole in its bottom surface for drainage. A sensing tube extends into the cup and is connected to switching means for sensing the presence of a predetermined fluid level in the cup and triggering an alarm in response thereto. Fluidic switching means which comprise a digital fluid amplifier are shown.
