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 charge conduit (50) at least partially within the interior. The discharge conduit has an interior and an exterior. A liquid level measurement assembly (82; 200; 250; 300; 400) is mounted to the second port and comprises: a tube (100) at least partially within the tank interior and having an interior sealed relative to the surrounding tank interior and an exterior; a float (120; 220) surrounding the tube; and a member (122; 222; 252; 302) axially movable within the tube interior. One of the float and the member comprises an upper magnet (130; 230) and a lower magnet (132; 232). The other of the float and the member magnetically cooperates with the upper magnet and the lower magnet to relatively axially trap the member to the float.
