A method for manufacturing a nozzle cap, the method including attaching an antenna printed circuit board (PCB) strip to an inner cover surface of an antenna cover; and inserting the antenna cover into a scallop defined by a circumferential wall of a cap body to position the antenna PCB strip between the antenna cover and the circumferential wall, the circumferential wall defining an outer wall surface, the antenna cover covering the scallop, the scallop extending radially inward into the circumferential wall relative to a first portion and a second portion of the outer wall surface, the scallop circumferentially positioned between the first portion and the second portion of the outer wall surface.

A method for installing a sensor assembly in a fire hydrant includes sequentially feeding components of the sensor assembly through an aperture in an upper standpipe of the fire hydrant. The components of the sensor assembly include a sensor unit, a conduit coupled with the sensor unit and extending away therefrom, and a series of rigid tubes surrounding the conduit and arranged in an end-to-end manner. The conduit is fed through the aperture along with the series of rigid tubes, and at least one of the series of rigid tubes has a length greater than a diameter of an interior of the fire hydrant.

A pressure monitoring system for a wet barrel hydrant includes an outer housing comprising a substantially cylindrical sidewall shell and a cap coupled to the substantially cylindrical sidewall shell, a center axis extending centrally through the pressure monitoring system; a pressure sensor configured to measure a pressure of a fluid received in the wet barrel hydrant; and an antenna assembly comprising an antenna, the antenna configured to send signals representative of pressure data measured by the pressure sensor, wherein the antenna assembly is circumferentially surrounded by the cap and is axially spaced from the substantially cylindrical sidewall shell.

A suction inlet valve for a fire truck pumper includes an adjustable design to permit connection at either 0 degrees or 30 degrees to a pumper so as to save space and increase utility. The suction inlet valve also includes a wider body portion that allows a size of the valve opening to be increased so as to increase throughput by approximately 80% to meet the higher capacity of newer pumpers. The suction inlet valve may include a visual indicator that indicates the position of the float of the valve, which may be representative of the flow.

A fire hydrant security system includes a fire hydrant cap and a specialized wrench for the fire hydrant cap. The cap includes: a body having an open end and a closed end; internal threads disposed within the open end and configured for engagement with a fire hydrant outlet; a first circular depression centrally disposed on an exterior of the closed end; and a second circular depression disposed within the first circular depression and positioned between a center of the first circular depression and a periphery of the first circular depression. The specialized wrench includes: an elongated handle; a first circular protuberance disposed on the elongated handle and configured to fill the first circular depression; and a second circular protuberance disposed on the first circular protuberance, positioned between a center of the first circular protuberance and a periphery of the first circular protuberance, and configured to fill the second circular depression.

An infrastructure monitoring assembly includes a nozzle cap defining an internal cavity; an antenna positioned at least partially external to the internal cavity; and the antenna covered with a non-metallic material. An infrastructure monitoring assembly includes a nozzle cap defining a first end and a second end, the first end defining a threaded bore configured to mount on a nozzle of a fire hydrant; a cover coupled to the nozzle cap opposite from the first end; an enclosure positioned at least partially between the cover and the first end, the enclosure at least partially defining a cavity; a monitoring device positioned within the cavity; and an antenna positioned between the cover and the first end of the nozzle cap, the antenna connected in electrical communication with the monitoring device, the antenna covered by a non-metallic material.

A freeze resistant wall hydrant including an outdoor housing joined to the outer end of an outlet tube for securing to a building and a fitting joined to the inner end of the outlet tube for coupling to a water supply. The fitting includes a fluid closure valve having a valve part movable between first and second positions for closing and opening the valve. A stem extends through the outlet tube and has an outer end coupled to a handle of the outdoor housing and an inner end coupled to the valve part. The handle moves the valve part to close and open the valve. The outlet tube and the stem can each be made from a cross-linked polyethylene or flexible plastic to facilitate installation of the wall hydrant. Methods for using or resizing the wall hydrant are provided.
