Abstract
A fire suppressant storage device (20) comprising: a tank (22) having a first port and an interior for storing fire suppressant; and a discharge assembly mounted to the first port. The discharge assembly has a discharge valve (48) and a discharge conduit (50) at least partially within the interior. The discharge conduit has an interior surface (60) and an exterior surface (58). The discharge assembly further comprises a gauge (80) on the discharge conduit.
Claims20
A fire suppressant storage device (20) comprising:
- a tank (22) having a first port and an interior for storing a fire suppressant;
- and
- a discharge assembly mounted to the first port and comprising:
- a discharge valve (48);
- and
- a discharge conduit (50) at least partially within the interior and having:
- an interior surface (60);
- and
- an exterior surface (58),
- wherein the discharge assembly further comprises:
- a capacitive gauge (80) on the discharge conduit comprising:
- a first conductor (82A);
- a second conductor (82B) spaced apart from the first conductor;
- a plurality (180A) of first branches (182A) of the first conductor extending away from the second conductor on the discharge conduit;
- and
- a plurality (180B) of second branches (182B) of the second conductor extending away from the first conductor on the discharge conduit opposite respective said first branches.
A method for manufacturing a fire suppressant discharge assembly, the discharge assembly comprising:
- a discharge valve (48);
- and
- a discharge conduit (50) having:
- an interior surface (60);
- and
- an exterior surface (58),
- the method comprising:
- forming, in situ on the discharge conduit, a gauge (80) having a first conductor (82A) and a second conductor (82B), the forming including providing a plurality of branches of the first conductor on the discharge conduit extending away from the second conductor and a plurality of branches of the second conductor on the discharge conduit extending away from the first conductor.
