Infrastructure monitoring devices, systems, and methods
An infrastructure monitoring assembly includes a nozzle cap, the nozzle cap comprising a metallic material; an antenna cover, the antenna cover attached to the nozzle cap, the antenna cover comprising a plastic material, the antenna cover defining an antenna cavity; and an antenna extending into the antenna cavity. An infrastructure monitoring assembly includes a fire hydrant, the fire hydrant defining a nozzle; a nozzle cap, the nozzle cap comprising a metallic material, the nozzle cap attached to the nozzle and sealing the nozzle; an antenna cover attached to the nozzle cap, the antenna cover comprising a plastic material, the antenna cover defining an antenna cavity; and an antenna disposed within the antenna cavity.
1. An infrastructure monitoring assembly comprising:
a fire hydrant, the fire hydrant defining a nozzle, the nozzle defining external threading at a nozzle end of the nozzle;
a nozzle cap, the nozzle cap comprising a metallic material, the nozzle cap defining a first nozzle cap end and a second nozzle cap end, a threaded bore extending into the nozzle cap from the second nozzle cap end to a bore shoulder defined between the first nozzle cap end and the second nozzle cap end, the threaded bore engaging the external threading, a gasket contacting the nozzle end and the bore shoulder in sealing engagement and sealing a nozzle bore of the nozzle;
an antenna cover attached to the nozzle cap, the antenna cover comprising a non-metallic material, the antenna cover defining a first antenna cover end and a second antenna cover end, the first antenna cover end defined opposite from the second antenna cover end, the second antenna cover end positioned between the first nozzle cap end and the bore shoulder of the nozzle cap, the second antenna cover end positioned between the first antenna cover end and the second nozzle cap end; and
an antenna covered by the antenna cover.
2. The infrastructure monitoring assembly of claim 1 , further comprising a sensor disposed within an enclosure, the sensor configured to monitor a fluid within the nozzle bore.
3. The infrastructure monitoring assembly of claim 2 , wherein the enclosure is sealed by a cover, and wherein the sensor is isolated from the fluid.
4. The infrastructure monitoring assembly of claim 2 , wherein at least a portion of the enclosure is positioned between the first nozzle cap end and the bore shoulder.
5. The infrastructure monitoring assembly of claim 1 , further comprising a transmitter disposed within an enclosure, the antenna connected to the transmitter, wherein the enclosure is disposed within the nozzle cap, wherein the nozzle cap defines a hole extending through the nozzle cap, and wherein the antenna is connected to the transmitter through the hole.
6. The infrastructure monitoring assembly of claim 5 , wherein the antenna cover comprises a plastic material.
7. The infrastructure monitoring assembly of claim 1 , wherein at least a portion of the antenna is positioned external to the nozzle cap, and wherein the portion of the antenna is at least partially covered by the antenna cover.
8. The infrastructure monitoring assembly of claim 1 , wherein the nozzle cap defines a nozzle cap shoulder, and wherein the antenna cover engages the nozzle cap shoulder.
