A sensing device for a hydrant, the sensing device including a housing defining a portion of an operating stem of the hydrant; a sensor located entirely within the interior cavity of the hydrant body and configured to measure a property of a fluid of the fluid distribution system; and an antenna in communication with the sensor and positioned within the housing.

A fire hydrant assembly for use with an irrigation riser stub may include a generally cylindrically-shaped main body having an open end and a closed end. The open end of the main body has an inside diameter that is sized to slidably receive an end portion of the irrigation riser stub. A seal disposed within the open end of the main body is sized to sealingly engage the irrigation riser stub. A nipple having a threaded end and a plain end is mounted within an opening provided in a side portion of the main body so that the threaded end may be threaded onto a fire hose assembly. An actuator shaft extends through a shaft opening defined by the closed end of the main body so that a head end of the actuator shaft is disposed outside the main body and so that a distal end of the actuator shaft is disposed within an interior cavity defined by the main body. A yoke mounted to the distal end of the actuator shaft is sized to operatively engage a valve stem associated with the irrigation riser stub.

A method of installing an Emergency Flow Restrictor Device (EFRD) on a pipeline without stopping the flow of fluid through the pipeline includes the steps of: assembling first and second face plates on a pipeline such that the first and second sealing face are in face to face, spaced relation; assembling a cutting device between the first face plate and the second face plate; assembling a valve body that has an access opening on a length of pipeline such that the valve body encloses the first and second face plates and the cutting device; installing an access valve on the access opening; operating the cutting device to sever the pipeline between the first and second sealing faces; retracting the cutting device and severed section of pipeline; and attaching a valve gate member of the EFRD to the access opening.
