A fire hydrant barrel includes a body having at least one wall and an anti-rotation pin opening through the at least one wall. The at least one wall defines an internal cavity. The fire hydrant barrel also includes a stem extending through the cavity of the body. The stem has an anti-rotation element, and the anti-rotation pin opening and the anti-rotation element are configured to receive an anti-rotation pin to lock the stem from rotating with respect to the body.

A fire hydrant includes an upper barrel, which further includes a body and at least one outlet. The body has a longitude, a longitudinal axis, a first portion, and a second portion, the first portion forming a first length of the longitude, the second portion forming a second length of the longitude, the first portion coupled to the second portion, the body having at least one wall defining an internal cavity. The first portion has a first dimension spanning the cavity perpendicular to the longitudinal axis between opposing points on the at least one wall. The second portion has a second dimension spanning the cavity perpendicular to the longitudinal axis between opposing points on the at least one wall. The first dimension is greater than the second dimension.

An automatic fire hydrant water supplying system provides hydrant supply water to a fire truck having a water pump; a water pump master intake valve; a water-supply fire hose, a pressure sensor upstream of the master-intake-valve, and a water-pump control system. The automatic fire hydrant water supplying system has a remotely-controllable hydrant discharge valve connectable to the hydrant and to the fire-hose. A remotely-controllable air bleed valve is in fluid communication with the master-intake-valve and the fire-hose. The water-pump control system determines whether a pressurized volume in the fire hose upstream of the master-intake-valve input port is air or water based on a difference in density between air and water as sensed by the pressure sensor and if the pressurized volume is air causes the air to be vented to atmosphere through the air-bleed-valve before opening the master-intake-valve to provide hydrant supply water to the water pump.

Disclosed is a valve including: a body; a closure member; and a closure member control rod, the control rod extending inside the body at least partially within a fluid flow area. The control rod includes, in the fluid flow area, at least one flowmeter including: a tubular body having two axial ends; a flow measuring device supported by the tubular body and associated with the tubular body so as to enable a flow of fluid flowing outside the tubular body to be measured, and the electrical connection; and an electrical connection extending outside of the tubular body and passing through the tubular body by at least one fluid-tight passage.

A nozzle cap assembly includes a nozzle cap configured to mount on a fire hydrant, the nozzle cap housing defining an inner surface and an outer surface, the inner surface defining a nozzle cap cavity within the nozzle cap; an antenna enclosure mounted to the nozzle cap, a portion of the antenna enclosure disposed external to the nozzle cap; and an antenna positioned within the antenna enclosure.

A hose coupling for a hydrant has a ventilation device. The ventilation device has a non-return valve that is received in a receptacle incorporated into an outer flange of the hose coupling.
