Abstract
A fire suppressant storage device (20) comprises: a tank (22) having a first port (40), a second port (70), and an interior (32) for storing fire suppressant. A discharge assembly (46) is mounted to the first port and comprises: a discharge valve (48); and a discharge conduit (50). The discharge conduit is at least partially within the interior and has an interior and an exterior. A liquid level measurement assembly is mounted to the second port and comprises: a tube (100) at least partially within the interior and having: an exterior and an interior sealed relative to the surrounding tank interior. A float (120) surrounds the tube and has one or more magnets (130) and having a range of motion. A plurality of magnetic field sensors (152, 154) are along a carrier (150) within the tube interior. The carrier extends from a proximal end to a distal end. The plurality of magnetic field sensors (152, 154) comprise: a first plurality of one-dimensional sensors (152); and at least two three-dimensional sensors (154) distally of the first plurality.
